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: The embodiments presented herein relate to concepts designed to eliminate the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature. In an example embodiment, a microcatheter with an enlarged distal section is described. The enlarged portion of the microcatheter may be located close to the inner diameter of the guide catheter in order to reduce any open space between the microcatheter and the guide catheter, and the guidewire can be placed through the microcatheter and used to guide the system. The microcatheter can include one or more marker bands to aid in aligning the microcatheter correctly relative to the guide catheter. After the guide catheter and microcatheter are tracked to the appropriate treatment site, the microcatheter can then be used to deploy various medical devices to treat a patient.

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.
