Abstract:
1. A method for deployment of an endoluminal device in a distal location in a body lumen from a proximal location, the method comprising the steps of: (a) inserting an introducer into the body lumen having a lumen wall, the introducer comprising a retrograde portion, an anterograde portion comprising a distal tip and an anterograde sheath attached proximally to the distal tip, a shaft attached to the distal tip and extending concentrically through a central lumen defined by the anterograde portion and retrograde portion, an endoluminal device mounted concentrically over the shaft in the central lumen and having a distal end contained by the anterograde portion and a proximal end contained by the retrograde portion, and an inflatable balloon mounted radially outside the retrograde portion for anchoring the endoluminal device during deployment of the device; (b) aligning the proximal end of the device in a deployment location; (c) retracting the retrograde portion to allow a proximal portion including the proximal end of the endoluminal device to deploy; (d) advancing the retrograde portion so that the balloon is aligned axially within the proximal portion of the device; (e) inflating the balloon to compress the proximal portion of the endoluminal device against the lumen wall; and (f) extending the shaft to distally advance the anterograde sheath to deploy a remaining portion of the endoluminal device.
