Advanced endovascular graft delivery system and method of treatment

摘要

This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

主权项

1. A method of delivering an endovascular device into a bodily lumen comprising:
providing a tubular endovascular device comprising biocompatible material, an inflatable channel and an expandable stent, wherein at least a portion of the inflatable channel comprises a biocompatible polyester material; providing an inflation material comprising a multi-component flowable liquid composition and optionally a radiopaque component or a contrast medium, wherein at least one component of said multi-component flowable liquid composition comprises an inert biocompatible material selected from the group consisting of saline, a buffer, and a combination thereof and wherein another component of said multi-component flowable liquid composition comprises a component comprising polyethylene glycol; delivering the tubular endovascular device into a bodily lumen; inflating the inflatable channel with the liquid inflatable material to provide an inflated channel; and curing the inflation material in vivo from about three minutes to about twenty minutes; wherein the inflated channel is securable against the bodily lumen; and wherein the cured inflation material is biocompatible and has long term stability of at least ten years in vivo.
