Abstract: A stent with varying porosity is described. The stent can be comprised of multiple stents attached together. A braided stent may have selected regions of increased thickness. The stent may be comprised of wires that are welded together at their ends in order to minimize vessel trauma. The stent may comprise a helically wound radiopaque wire wound through the stent.

Abstract: Implant engagement mechanisms are disclosed for maintaining engagement with a stent until it has been fully deployed and expanded from a catheter or sheath. The apparatus, method and system involving these engagement mechanisms allow a physician to withdraw or retract a sheath prior to full deployment, thereby allowing for redeployment of the stent at a more desirable position.

Abstract: Disclosed is a method, apparatus, and kit for assisting the expansion of a self-expanding stent, especially within highly curved or tortuous blood vessels. An elongated pusher having an expandable distal mesh portion can be positioned within a self-expanding stent, expanding during delivery to provide extra expansion force to the stent to ensure the stent properly expands.

Abstract: In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.
