All VCDs have demonstrated rapid hemostasis and a decreased time to ambulation when compared to manual compression(1-4). Vasoseal™ has been associated with the highest risk of infection, while Angiolink™ and Starclose™ are felt to have the lowest risk (1-4). Angioseal™ theoretically has a higher risk of thromboembolic events due to the intravascular collagen anchor. The suture-mediated devices utilize primary healing (end to end anastomosis at the arteriotomy site), but are the most complex technically and have the highest rate of device and operator failure. Collagen and ProcoagulantsThe Vasoseal™ closure device (Datascope Corp., Montvale, NJ) was introduced in 1995 (revised in 1999and 2002) and utilizes an extravascular Type-1 collagen produced from bovine tendons. When deployed at the arteriotomy site the collagen initiates coagulation by activating platelets (secondary healing). Vasoseal™ isFDA approved for both diagnostic and interventional procedures, with a single device used for 5-8 French sheath sizes. The Angio-Seal™ device (St. Jude Medical, St. Paul, MN) achieves hemostasis by sandwiching the puncture site between an intravascular bio-absorbable (over 8-12 weeks) anchor and an extravascular bovine.......................Read more HERE (its a verified safe download from Adrive)
