Abstract:
1. A method for deployment of a multi-part endoluminal device in a distal location in a body lumen from a proximal location, the device having at least a first portion and a second portion, each portion having a distal end and a proximal end, the method comprising the steps of: (a) deploying the first portion in a body lumen by aligning the first portion distal end in a desired location and then deploying a remainder of the first portion including the first portion proximal end; and (b) deploying the second portion in the body lumen by aligning and anchoring the second portion proximal end in a desired location and then deploying a remainder of the second portion including the second portion distal end in overlapping engagement with the first portion proximal end, the step of deploying the second portion comprising: (b1) inserting an introducer into the body lumen, the introducer comprising an anterograde sheath mounted over the second portion and attached distally to a distal tip attached to a distally movable shaft extending axially through the second portion; (b2) aligning the introducer in a deployment location; (b3) extending the shaft to distally advance the anterograde sheath to deploy at least a distal section of the second portion; and (b4) removing the introducer from the body lumen, wherein the introducer further comprises anchoring means for anchoring a proximal section of the second portion during deployment of the second portion from a proximal end to a distal end of the second portion, the method further comprising aligning the proximal end of the second portion with the deployment location in step (b2), anchoring the proximal end prior to or during step (b3), and releasing the proximal end prior to or concurrently with step (b4).
