An implant delivery system may have a pusher. The pusher may have an elongated shape. A distal end of the pusher may be configured to connect to an implant. The implant delivery system may have a tether connected to the pusher and to the implant. The implant delivery system may have a heating element mounted over the tether biased to contract a first surface of the heating element towards a second surface of the pusher. The implant delivery system may have an expander disposed between the first surface of the heating element and the second surface of the pusher. The expander may be configured to melt, allowing the first surface to contact the second surface, upon activation of the heating element.

Implant delivery system

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.

Releasable delivery system

A system and method of delivering and detaching an implant within a body of a patient is described. A tether connects an implant with a delivery device. The delivery device includes a heater coil through which the tether passes. The inner diameter of the heater coil is about the same size or slightly larger than the outer diameter of the tether, allowing the tether to more efficiently break the tether during delivery.

The present specification discloses improved liquid embolic compositions, methods of making such liquid embolic compositions, and methods and uses for such liquid embolic compositions.

Liquid embolic compositions

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.

Stent

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.

Stent and stent delivery device

A braided embolization apparatus is disclosed. In at least one embodiment, a plurality of individual strands are braided together as an embolic braid having a proximal end and an opposing distal end, the embolic braid forming an elongated primary shape capable of being inserted into a catheter. During use of the apparatus, upon the distal end of the embolic braid subsequently exiting the catheter, the embolic braid is configured for moving into a shape memorized secondary shape capable of filling a target area of a patient's vascular system.
