PORTLAND, Ore.--(BUSINESS WIRE)--HemCon Medical Technologies, Inc., announced today that the U.S. Court of Appeals for the Federal Circuit granted HemCon's motion to stay the injunction and final judgment (including the damages award) obtained against it in a patent infringement case brought by Marine Polymer Technologies, Inc. The stay halts any enforcement of the lower court’s injunction and damages award while HemCon attempts to have both overturned on appeal, a process expected to take on the order of 12 to 18 months to complete. As a result, HemCon can continue selling its chitosan-based wound care products and will not be required to pay financial damages during this appeal process.
"HemCon is extremely pleased that the appellate court agreed that HemCon could continue selling its product line during the pendency of the appeal. We will urge on appeal that the lower court decision finding infringement was incorrect, in part because the Marine Polymer patent is invalid when properly interpreted," said John W. Morgan, HemCon's President and Chief Executive Officer. "The stay is a victory for HemCon's customers, including military personnel whose lives are being saved by HemCon products, and hospital patients who benefit from reduced infection risk and better hemostasis."
The stay is the most recent decision in the patent infringement action instituted by Marine Polymer Technologies, Inc. "In imposing the stay, the Court of Appeals concluded that HemCon had shown a strong likelihood of succeeding on appeal, or at least a substantial case on the merits and that any potential harm weighed in HemCon’s favor," Morgan explained. "We believe the appeals court will ultimately agree with our conclusion that our products do not infringe the Marine Polymer patent. We look forward to further presenting our case to the Court.”
HemCon Medical Technologies, Inc. (www.hemcon.com) founded in 2001, develops, manufactures, and markets innovative technologies to control bleeding and infection resulting from trauma or surgery. HemCon products are designed for use by military and civilian first responders as well as medical professionals in hospital, dental and clinical settings where rapid control of bleeding is of critical importance. HemCon is headquartered in Portland, Ore., with additional commercial operations in Ireland and the Czech Republic.

Ethicon Inc announces submission of BLA for Fibrin Pad
Ethicon Inc, a Johnson & Johnson (NYSE: JNJ) company, reported on Thursday the submission of a Biologic License Application (BLA) to the US Food and Drug Administration (FDA) for the Fibrin Pad to aid in stopping soft tissue bleeding during surgery.
The company's BLA submission includes efficacy and safety data from a randomised, controlled clinical study in which the Fibrin Pad was used as an adjunct to hemostasis in soft tissue bleeding. According to Ethicon the Fibrin Pad is a novel product candidate that combines two methods of action: biomaterials and plasma-derived biologics (Human Fibrinogen and Human Thrombin).The Fibrin Pad is intended for use by surgeons as an adjunct to hemostasis when surgical methods are ineffective or impractical to control bleeding.
ArterX™ Clinical Trial Results Announced at Veith Meeting
MOUNTAIN VIEW, Calif., Nov. 18, 2010 /PRNewswire/ -- US clinical trial results for Tenaxis' investigational vascular surgical sealant, ArterX, were presented today at the Veith Meeting in New York. William M. Stone, MD of the Mayo Clinic, Scottsdale AZ reported a more than 20% margin of improvement for ArterX Surgical Sealant in the sealing of vascular suture lines compared with a control group featuring a commercially available gelatin foam/thrombin combination.
In a presentation titled "A Novel More Effective Glue-Sealant (ArterX) for Hemostasis at Vascular Suture Lines and Other Sites," Dr. Stone reported that ArterX Surgical Sealant achieved immediate hemostasis more than 60% of the time in a 217 patient clinical trial conducted at 11 different hospitals in the US.
President and CEO, David Smith, commented, "We are delighted with the preliminary results of our US clinical trial. We were also able to show a statistically significant reduction in operating time of 36 minutes in the ArterX group, and ArterX patients were discharged from hospital after 4.1 days, an improvement of 1.3 days over the control group. If approved, we believe that ArterX Surgical Sealant will yield economic benefits for surgeons and hospitals that adopt it."
ArterX Surgical Sealant is currently under review by the FDA and is not available for sale in the USA.
ArterX is CE marked for the EU.

Blood-clotting drug given to wounded soldiers can cause heart attacks
A drug given to wounded soldiers in Iraq and Afghanistan may be putting their lives in further danger by causing heart attacks and strokes.
The treatment is used to stop serious bleeding in injured troops, but trials show the drug increases the risk of blood clots forming in arteries, which can kill or cause complications that result in amputation.
The dangerous side effects are all the more concerning because years of trials have yet to prove the drug is any better at saving the lives of injured soldiers than a placebo.
The drug, called NovoSeven, was licensed more than a decade ago to stop bleeding in haemophiliacs, but is used by military doctors and in civilian hospitals on an "off-label" basis to treat patients suffering from major blood loss due to trauma or surgery. The drug, also known as recombinant factor seven, costs several thousand pounds per patient but an effective alternative called tranexamic acid costs just £5 per patient.
A spokesman for the Ministry of Defence confirmed that NovoSeven was used by UK forces as "a medicine of last resort", when all other attempts to stem bleeding had failed. The US military also uses the drug.
Prof Ian Roberts, an expert in trauma care at the London School of Hygiene and Tropical Medicine, warned in 2006 that NovoSeven was being used off-label before trials had clarified whether or not it helped save lives.
"There are both civilian patients and wounded soldiers who will have been given this drug and the best evidence shows they would not have benefited, but would have experienced heart attacks, strokes and possible amputations," Roberts said.
By continuing to use the drug, the military and hospital surgeons were leaving themselves vulnerable to legal action, he added. "You cannot defend giving this treatment outside of a randomised controlled trial," he said.
He added that the US military, which has used NovoSeven for years, should explain why it embraced the drug. "What advice were they acting on? Was the advice they received truly independent, or were people compromised in any way? It is important to know," he said.
Dr Mads Krogsgaard Thomsen, chief science officer at Novo Nordisk, the Danish company that makes NovoSeven, said the drug posed very low risk when used under licence to stop bleeding in haemophiliacs and for certain rare blood clotting disorders. "We cannot encourage as a company, by any means, the off-label use of NovoSeven. This is not something we are promoting and it is not something we are responsible for."
Thomsen estimates that between 10% and 20% of NovoSeven is used off-label. "Every now and then, physicians do use it as a last resort in patients that are otherwise likely to die," he said.
Roberts believes the case for using NovoSeven is weakened further by the availability of a much cheaper alternative drug, tranexamic acid, which is known to save lives in bleeding patients without dangerous side effects. A trial of tranexamic acid, called Crash-2, was published in the Lancet in June.
Marcel Levi, professor of internal medicine at Amsterdam Medical Centre, published a review of NovoSeven trials in the New England Journal of Medicine last week that was funded by NovoNordisk. "If you look at whether the drug stops bleeding, or whether fewer transfusions are needed, then many studies are positive. If the only thing that matters is mortality, then it is much harder to prove that this is a useful drug," he said.
Beverley Hunt, a consultant haematologist who worked on the Crash 2 trial at Guy's and St Thomas's Hospital in London, said: "The issue around the use of factor seven in patients with massive blood loss is that there is a lack of evidence to show us how clinically efficacious it really is, what dose to use and when to use it. The problem with using an agent that alters blood clotting is that it is a tightrope walk in reducing the risk of bleeding without increasing the risk of blood clots.
"The recent data showing that its use is associated with a 5% risk of arterial thrombosis means we should not be using it early in the management of massive blood loss. If however despite normal good practice, somebody is bleeding to death and you have nothing left, are you willing to take a 5% risk of arterial thrombosis, and the answer is yes you are."

X-ray crystallography reveals structure of precursor to blood-clotting protein
ST. LOUIS — Using state-of-the-art robotic and x-ray crystallographic equipment, researchers at Saint Louis University have revealed for the first time the molecular structure of the zymogen, or inactive, form of a blood-clotting enzyme.
In an article published in Proceedings of the National Academy of Sciences, Enrico Di Cera, M.D., chair of the department of biochemistry and molecular biology at Saint Louis University School of Medicine and lead researcher of the study, said the NIH-funded research offers important information about the protein.
“This research is very basic and very important,” said Di Cera. “It provides a missing link between the inactive zymogen form of thrombin and the mature enzyme generated upon vascular injury.”
Before thrombin becomes active, it circulates throughout the blood in the inactive zymogen form. When the active enzyme is needed, for example after a vascular injury, the coagulation cascade is initiated and the zymogen is converted into an active enzyme that causes blood to clot.
Blood clotting performs the important function of stopping blood loss after an injury. However, when triggered in the wrong conditions, clotting can lead to debilitating or fatal conditions like heart attack, stroke and deep vein thrombosis.
In previous laboratory research, Di Cera re-engineered thrombin to act as an anticoagulant, stopping blood from clotting and opening the door to the development of new therapeutic strategies for the treatment of thrombosis, the presence of blood clots in blood vessels, which is responsible for nearly a third of all deaths in the U.S.
While researchers have an understanding of the structure of active thrombin, very little was known about its zymogen form. In order to learn more, researchers used x-ray crystallography to gather data about the molecular structure of the protein.
The process involves growing a crystal of the protein, shooting x-ray beams through the crystal and analyzing the diffraction patterngenerated on a detector plate in order to detail the three-dimensional structure of the protein.
The structure of the zymogen form of thrombin provides crucial details about the activation mechanism that sheds light on the way the mature enzyme works. Future research can capitalize on these new findings to define better strategies for therapeutic intervention.
“Until now, we’ve known nothing about the zymogen form of thrombin or any blood-clotting enzyme,” said Di Cera. “All the structural information has been limited to the active form.
“We now know that the zymogen form of thrombin is very different from the mature enzyme, in ways that open new opportunities for therapeutic intervention.”
Established in 1836, Saint Louis University School of Medicine has the distinction of awarding the first medical degree west of the Mississippi River. The school educates physicians and biomedical scientists, conducts medical research, and provides health care on a local, national and international level. Research at the school seeks new cures and treatments in five key areas: cancer, liver disease, heart/lung disease, aging and brain disease, and infectious disease.

Baxter International raises outlook after third-quarter earnings beat expectations
Baxter International Inc.’s third-quarter earnings beat Wall Street expectations Thursday, propelled by a jump in sales in the company’s IV solutions business. After the company’s earnings release, Baxter’s stock price rose by more than 3 percent.
The Deerfield-based medical supply and pharmaceutical company posted earnings of $594 million, or $1.01 per diluted share, in the quarter ended Sept. 30, besting Wall Street’s consensus projections of 97 cents. Net income rose 12 percent from the same quarter in 2009, when the company earned $532 million, or 87 cents per diluted share.
In the 2009 quarter, the company incurred a one-time charge of $27 million for the retirement of a syringe pump. Without that cost, 2010 third-quarter earnings would have been 1 percent lower than 2009.
Still, the company raised the floor of its 2010 annual forecast from $3.93 to $3.96 per diluted share, and now expects 2 percent to 3 percent annual sales growth. Its previous forecast called for growth in the range of 1 percent to 3 percent. The top forecast figure remained at $3.98.
“We continue to aggressively manage general administrative and discretionary spending across the company,” Robert Parkinson, Baxter’s chairman and chief financial officer, said in a Thursday morning conference call. “We’re selectively investing in several key promotional activities aimed at demand creation, new product launches and driving future growth of our higher margin products.”
Baxter’s third-quarter revenue grew by 3 percent to $3.2 billion from last year’s $3.1 billion. The medical delivery sector, which manufactures intravenous solutions and sets, intravenous nutritional products, medical pumps and drug manufacturing products, spurred much of the company’s third-quarter momentum by racking up $1.2 billion dollars in sales, up 2 percent globally and 12 percent domestically.
The company’s bioscience division also is outperforming analysts’ expectations, led by developments in critical-care blood plasma replacement therapeutics. Sales at the division did not grow significantly during the quarter but have grown 3 percent so far this year, totaling $3.4 billion.
“We view this commentary, quarterly results, and outlook as all positives for the company and encourage investors to revisit what should be a core holding in the healthcare space,” said Daniel Owczarski, a financial analyst with Avondale Partners LLC.
In the first nine months, Baxter has earned $1.1 billion, or $1.79 per diluted share, down 35 percent from the same period last year, when the company earned $1.7 billion, or $2.66 per diluted share. Revenue, rose 3 percent to $9.3 billion, compared with last year’s $9.1 billion.

Seven U.S. Medical Centers Commence Study to Change Femoral Artery Cath Lab Access
REDWOOD CITY, Calif., Nov. 8, 2010 /PRNewswire/ -- Arstasis is pleased to announce that patient enrollment has begun in the RECITAL (A Patient Registry Evaluating Closure Following Access with the Arstasis One Access System) Study. The non-randomized, prospective, post-approval study is anticipated to enroll up to 500 patients in at least seven U.S. hospitals. The goal of the study is to observe the clinical safety and effectiveness of the Arstasis One Access System in patients undergoing diagnostic angiography procedures through the femoral artery.
The first patient was enrolled at La Paz Regional Medical Center inParker, Arizona. "We've begun performing Arstaotomy procedures routinely in our cath lab because they make femoral artery access safer for our patients, easier for me and my staff, and less expensive for our hospital compared with closure devices or manual compression," said Dr. Frank Kresock, chief of interventional cardiology at La Paz Regional Medical Center, the physician who performed the procedure.
Since 1959, physicians have been using the Modified Seldinger Technique (or "Seldinger Technique" for short) to insert flexible catheters into the femoral artery of patients for the purpose of performing procedures in the patient's arterial-vascular system. The most prevalent such procedure, angiography, is thought to be performed more than half a million times per month worldwide. At the end of every such case, each patient is left with a substantial hole in his/her femoral artery (upper inner thigh) which typically takes significant effort and cath lab resources to get to stop bleeding. With the Arstasis One Access System, however, physicians may create a shallow-angle needle pathway through the wall of the femoral artery. At the end of the procedure, when the sheath is withdrawn, the shallow-angle pathway collapses from the normal pressure of the patient's femoral artery blood flow from below and approximately 3-4 minutes of mild, non-occlusive finger-pressure from above, resulting in a quickly sealing access site.
"The Arstasis One femoral artery access system marks the beginning of a new approach to heart catheterization," commented Zoltan G. Turi, MD, the Director of the Vascular Center at Cooper University Hospital and Professor of Medicine at Robert Wood Johnson Medical School in Camden, New Jersey, and the national principal investigator of the RECITAL study. "We hope to show that patients who participate in this study benefit from femoral artery closure that has advantages over regular manual compression", Dr. Turi continued. "We are also interested in this technology because Arstasis facilitated closure, unlike vascular closure devices, does not result in any foreign materials being implanted."
The study will also assess patient satisfaction due to reduction of pain and discomfort as well as early mobility. In non-U.S. clinical trials the resulting closed access site was typically so secure that a patient could get up from his/her bed and begin walking hours sooner than would be the case with a standard femoral arteriotomy, sometimes as soon as those patients receiving Vessel Closure Devices.
"This procedure over the Angioseal, in my opinion, was 100% better because of the recovery time, less swelling and bruising. This is much better, I'm glad I got the Arstaotomy," said Russell McKenzie, Dr. Kresock's 75-year old patient at La Paz Regional Medical Center who was the first to enroll in the RECITAL study.
Detailed information about the Arstasis One, and the Arstaotomy procedure, is available at www.arstasis.com.

Researchers invent inkjet that prints out living skin
This is no horror movie, this is part of a recent presentation at the American College of Surgeons Clinical Congress, where Wake Forest Institute for Regenerative Medicine researchers had a super fun time showing off their results from a printer that uses living cells instead of ink. Fluid based inkjet technology used in the very printers you’ve got in your home or office is used to lay down cells, printing large sections of living tissue down on cut up or damaged areas of the body. These fine folks from the Institute note that “any loss of full-thickness skin of more than 4 cm in diameter will not heal by itself,” and that with this device, (refined and tested extensively, of course,) skin that might have been otherwise damaged horrifically can now be patched up to a much higher level of healthiness. Testing has occurred on mice revealing advanced healing by the second and third week of recovery and complete closure of the skin by the end of week three on wounds that would otherwise still be open to infection.
The printer works with two heads, one that dispenses skin cells mixed with fibrinogen (a blood coagulant) and type I collagen (connective tissue’s main component in scars), the other which sends out thrombin (another coagulant.) Together these create a chemical reaction and form fibrin, another protein that works on the clotting of blood. On top of this is one more layer printed by the printer: keratinocytes – the outer layer of skin we’ve all got right this moment.
Future research will be done on the pigs who, if you know your Gangs of New York lore, are great to practice stabbing on because they’ve got skin that very closely resembles human skin. Will this device ever hit your local wartime hospital or town hospital? Who can tell?
