First Claim
Patent Images
1. A trigger wire release mechanism for releasing one or more retained ends of a prosthesis, the trigger wire release mechanism comprising:
- a prosthesis retaining device having proximal and distal ends and which is arranged to engage at least one end of the prosthesis;
one or more trigger wires each having a distal end and a proximal end, the proximal end being arranged to selectively couple the prosthesis retaining device to the prosthesis;
a control mechanism comprising an elongate body member and a lever, wherein the elongate body member has an exterior surface and an interior surface, the interior surface defining a chamber extending longitudinally with the elongate body member, and wherein the lever is connected to the elongate body member on the exterior surface with a pivot configured to be disengaged by an operator to remove the lever from the control mechanism;
wherein each of the one or more trigger wire distal ends are operably connected to the lever to selectively disengage the prosthesis retaining device from the prosthesis and wherein when the operator removes the lever, the one or more trigger wires are withdrawn from the prosthesis.

10. A prosthesis deployment device, comprising:
-
a prosthesis having proximal and distal ends, further comprising at least one self-expanding stent; a prosthesis retaining device having proximal and distal ends and which is attachable to at least one of the proximal and distal ends of the prosthesis; one or more trigger wires each having a distal end and a proximal end, the proximal ends of the trigger wires being arranged to selectively couple the prosthesis retaining device to at least one of the proximal or distal ends of the prosthesis; a control mechanism comprising an elongate body member and a lever, wherein the elongate body member has an exterior surface and an interior surface, the interior surface defining a chamber extending longitudinally with the elongate body member, and wherein the lever is connected to the elongate body member on the exterior surface with a releasable pivot connection configured to be disengaged by an operator to remove the lever from the control mechanism; wherein at least one of the one or more trigger wire distal ends is operably connected to the lever to selectively disengage the prosthesis retaining device from the prosthesis wherein when the operator removes the lever, the one or more trigger wires are withdrawn from the prosthesis. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An intraluminal deployment device, comprising:
-
a prosthesis having proximal and distal ends, further comprising at least one self-expanding stent; a prosthesis retaining device having proximal and distal ends and which is attachable to at least one of the proximal and distal ends of the prosthesis; a plurality of trigger wires each having a distal end and a proximal end, the proximal ends of the trigger wires being arranged to selectively couple the prosthesis retaining device to at least one of the proximal or distal ends of the prosthesis; a control mechanism comprising an elongate body member and a lever, wherein the elongate body member has an exterior surface and an interior surface, the interior surface defining a chamber extending longitudinally with the elongate body member, and wherein the lever is releasably and pivotally connected to and configured with the elongate body member on the exterior surface so that an operator can remove the lever; wherein the distal ends of the plurality of trigger wires are operably connected to the lever to selectively disengage the prosthesis retaining device from the prosthesis and wherein when the operator removes the lever, the plurality of trigger wires are withdrawn from the prosthesis.
