ABSTRACT:
An expandable stent and delivery system is provided for treating body vessel defects, such as partially occluded blood vessels and aneurysms. The delivery system includes a core member having a non-cylindrical retraction member with extending portions configured to extend between struts of the stent. The stent includes enlarged anchor members that cooperate with the retraction member to secure the stent to the core member for movement within a delivery catheter and deployment to a body vessel defect. The extending portions provide a greater contact area than would be possible with a cylindrical retraction member, which is especially beneficial when retracting a partially deployed stent into the catheter.
