Methods and devices for deploying an implant in curved anatomy
First Claim
1. A method for deploying an implant in a curved vessel, comprising the steps of:
- providing a steerable catheter having a proximal end, a distal end, and an endoluminal implant carried in a distal region of the catheter, the catheter having a longitudinal axis at the distal end of the catheter, the endoluminal implant having a leading edge and a trailing edge;
advancing the catheter into a curved region of a vessel having a centerline;
steering the catheter to substantially align the longitudinal axis with the centerline of the vessel at the region where the implant lies within the vessel; and
deploying the implant to achieve substantially uniform wall contact with the endoluminal surface of the vessel.

Abstract
Methods and devices for deploying an endoluminal implant in a curved vessel. The devices include steerable catheters having a control member that extends to the distal end and operates to bend the catheter. In other cases, the stent includes a longitudinal adjustment member attached near the leading edge of the stent and operates to shorten or lengthen the stent and thereby induce a curvature. The stent is carried in a distal region of the catheter that is advanced into a curved region of a vessel. The catheter is bent and/or the stent is curved using the longitudinal adjustment member, and the stent is deployed to achieve uniform wall contact with the endoluminal surface of the vessel at the lesser curvature.

16. A medical device for deploying an implant in a curved vessel, comprising:
-
an elongate member having a proximal end and a distal end; an endoluminal implant releasably carried near the distal end of the elongate member; and a control member having a distal end attached at a point near the distal end of the elongate member and extending proximal from the point of attachment, wherein the control member causes a distal region of the catheter to bend when an axial displacement is applied to the control member.
