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, the introducer comprising a retrograde portion; an anterograde portion; a shaft having a distal tip; an inner sheath mounted concentrically over the shaft with the endoluminal device mounted concentrically over the inner sheath; an anterograde sheath proximally attached to the shaft distal tip, mounted over the endoluminal device in the anterograde portion of the introducer, and axially moveable relative to the inner sheath; and a balloon in the retrograde portion for anchoring the endoluminal device during deployment of the device from a proximal end to a distal end of the device, wherein the introducer includes only one balloon; (b) aligning the introducer in a deployment location, aligning the proximal end of the device with the deployment location, and inflating the balloon to anchor the proximal end of the endoluminal device against the retrograde sheath so that the retrograde sheath can not move relative to the proximal end of the endoluminal device; (c) distally advancing the anterograde sheath by extending the shaft to deploy at least a proximal portion of the endoluminal device; and (d) deflating the balloon, retracting the retrograde sheath, and removing the introducer from the body lumen.
