Implant delivery device

Abstract

A delivery device may include a support structure for imparting a desired stiffness, springiness, and kink-resistance. The delivery device may include a core wire and/or one or more electrical wires which are electrically connected to a detachment mechanism. A medical device such as an implant may be attached to the delivery device by a detachment mechanism. A support structure may extend alongside or around the core wire to provide support for the delivery device, particularly when pushing a larger implant through a smaller catheter. The support structure may include a support wire alongside the core wire, a hypotube surrounding the core wire, a braid braided around the core wire, and/or a coil coiled around the core wire. The core wire may be formed from a non-memory-shape material such as stainless steel and the support structure may be formed from a memory-shape material such as Nitinol.
