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 x 68-mm Wallstent and 50-microm-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.
