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.
