Though we did not create the Stretch graft with improving patency in mind, some surgeons have reported greatly improved patency rates. We do not have an explanation for this occurrence. Dr. Tordoir of the Netherlands reports in his publication that perhaps the reason for less thrombosis and stenosis with the Stretch graft is the "lengthwise compliance of the prosthesis that may offer a better matching of the mechanical properties between the graft and native vessels."
Yes. The graft may be sterilized (if necessary) up to three times using methods and parameters described in the Instructions for Use.
We have never had a confirmed allergic response to ePTFE. PTFE is the most inert substance known and is very biocompatible.
