Percutaneous Large Arteriotomy Site Closure

Stanford University, 2005 - $16,675

Arteriotomies (the surgical incision of an artery) are required for all catheter-based procedures. Current medical practice requires a large, open incision, an invasive procedure which increases recovery time, hospital and procedure costs, and patient discomfort. To combat these problems, this E-Team developed a device that closes large arteriotomies percutaneously--that is, closes them through the skin in a minimally invasive procedure. The device consists of two components: a vessel-cutting tool, which creates an incision in the vessel of the specific size and shape of the catheter to be used, and a closure mechanism, made of a pre-placed nitinol structure, that provides complete hemostasis to the arteriotomy when the catheter is removed.
