Prosthesis deployment system
First Claim
1. A trigger wire release mechanism for releasing a retained end of a prosthesis, the trigger wire release mechanism comprising:
- a prosthesis retaining device arranged to engage an end of the prosthesis;
a trigger wire having a distal end and a proximal end, the distal end being arranged to selectively couple the prosthesis retaining device to the prosthesis;
a control mechanism comprising an elongate body member and a guide member including a securing member, the elongate body member having a proximal end and a distal end, an exterior surface, and an interior surface, the interior surface defining a chamber extending longitudinally with the elongate body member, wherein the securing member is disposed within the chamber;
wherein the trigger wire proximal end is operably coupled to the securing member in the chamber and the guide member is slidably disposed between a generally distal position and a generally proximal position along the elongate body member and the securing member is slidably disposed between a generally distal position and a generally proximal position within the chamber and with the guide member to selectively disengage the distal end of the trigger wire from the prosthesis retaining device and to selectively disengage the prosthesis retaining device from the prosthesis.

Abstract
A trigger wire release mechanism is disclosed that includes a control member for selectively releasing a trigger wire (22, 44) from a prosthesis retaining device. The control member includes an elongate body member (36) and a guide member (24, 25, 93, 94) slidably disposed on the elongate body member. The trigger wire 1 (22, 44) includes a distal end coupled to the prosthesis retaining device and a proximal end coupled to the guide member. The guide member (24, 25, 93, 94) can be moved from a distal end of the elongate body (36) to a proximal end of the elongate body, thereby disengaging the trigger wire (22, 44) from the retaining device. The control member may include a locking mechanism (120) for limiting the axial position of the guide member (24, 25, 93, 94) along the elongate body member (36). A prosthesis control member (81) is also disclosed. The prosthesis control member (81) is adapted to control the position of the prosthesis during deployment.
