Abstract
Purpose:
To describe an in vitro feasibility trial of a new percutaneous endograft delivery technique.
Methods and Results:
A water flow model of 9-mm (inner diameter) transparent plastic tubing was used to test the feasibility of sequentially delivering the components of an endograft through a 7-F sheath for assembly in situ. The tubular endovascular graft was fabricated from a 10-mm × 68-mm Wallstent and 50-μm-thick Dacron graft. The graft material was formed into a tube, attached with a suture to a guidewire, and delivered into the plastic tubing. The Wallstent was then delivered through the tubular graft and deployed, affixing the graft to the plastic tube wall. In 4 trials, only 1 attempt was not successful.
Conclusions:
These concepts and techniques may have implications in the development of percutaneously deliverable endovascular grafts.
