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: 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: A vascular implant may comprise at least a first layer having one or more drawn fill tube wires (DFT wires) and at least a second layer having one or more non-DFT wires. The first layer may be braided from only a single DFT wire, and the second layer may be braided from a plurality of non-DFT wire. A vascular implant may also include a connecting wire composed of a shape memory alloy and that is shape set prior to connection to one or more implant layers composed of DFT wires.

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.
