A method of making a self-expanding stent entails applying a bend stress sufficient to over-bend a portion of a wire by an amount in a range from about 85% to about 105%, where the wire comprises a Ni&#x2014;Ti alloy and includes from about 40% to about 46% cold work. The bend stress is then released, thereby forming a bend having a predetermined bend angle in the wire. The application and release of the bend stress are repeated on successive portions of the wire in order to create a series of bends along a length of the wire in a predetermined bend pattern. The wire comprising the predetermined bend pattern is then positioned about a mandrel in an expanded stent geometry and heat set. Thus, a self-expanding stent is formed.

Method of forming a bend of a predetermined bend angle in a shape memory alloy wire and method of making a self-expanding stent

A prosthesis deployment device having a elongate catheter body and a trigger wire guide concentric about the elongate catheter body where the trigger wire guide comprises three trigger wire lumens separate and apart from a guide wire lumen, with three trigger wires being at least partially disposed in the three trigger wire lumens and configured to engage a portion of a prosthesis to retain the prosthesis adjacent to the trigger wire guide.

Trigger wire system

A trigger wire guide for a prosthesis deployment device. The prosthesis deployment device has a proximal end extending to a proximal nose cone dilator and having a trigger wire or wires and trigger wire release mechanism to retain the proximal end of a prosthesis adjacent the nose cone dilator. The trigger wire guide retains the trigger wire or wires to prevent fouling of the trigger wire with a prosthesis when the prosthesis is carried on the deployment device. The guide can be crimped or soldered to a guide wire catheter or concentric with it.

An introducer for an expandable endovascular prosthesis having a self a self-expanding stent includes a proximal prosthesis positioning mechanism that has a retention device to retain the self-expanding stent and a control member to selectively release the retention device from the prosthesis. The retention device includes an opening forming a tapered cavity. The control member includes a plurality of loops coupled to the prosthesis and a trigger wire. The trigger wire passes through a first aperture of the retention device, through the plurality of loops, and through and a second aperture of the retention device to retain the loops.
