Releasable Delivery System

摘要

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.

主权项

1. A delivery pusher to deliver a stent within a delivery sheath for an endovascular procedure comprising:
an elongated member; a stent engagement mechanism located on a distal portion of the elongated member; wherein the stent engagement mechanism engages with the proximal portion of the stent when the stent is in a compressed configuration within the delivery sheath and disengages with the proximal portion of the stent as the stent exits the delivery sheath and expands to a full-sized configuration.
