Claims
- 1. A trigger wire guide for a prosthesis deployment device, the prosthesis deployment device being of a type having a guide wire catheter extending to a proximal nose cone dilator and having a trigger wire and trigger wire release mechanism adapted to retain the proximal end of a prosthesis distally of the nose cone dilator, wherein the trigger wire guide comprises a duct along at least part of the length of the guide wire catheter, the duct having at least one lumen for a trigger wire and an aperture in the duct adjacent the nose cone dilator for the trigger wire to exit the duct to engage the prosthesis, a stent of the prosthesis or a suture retaining the prosthesis to thereby retain the prosthesis.
- 2. A trigger wire guide as in claim 1 wherein the duct is coaxial with and surrounding the guide wire catheter.
- 3. A trigger wire guide as in claim 1 wherein the duct has three lumens for trigger wires.
- 4. A trigger wire guide as in claim 1 wherein the duct is formed by a concentric tube around the guide wire catheter and crimped thereto.
- 5. A trigger wire guide as in claim 1 wherein the duct is formed by a V shape cross section component retained to the guide wire catheter.
- 6. A trigger wire guide for a prosthesis deployment device, the prosthesis deployment device being of a type having a proximal end extending to a proximal nose cone dilator and having a trigger wire or wires and trigger wire release mechanism adapted to retain the proximal end of a prosthesis adjacent the nose cone dilator, comprising a trigger wire guide disposed on the deployment device to retain the trigger wire or wires to prevent fouling of the trigger wire with a prosthesis when the prosthesis is carried on the deployment device.
- 7. A prosthesis deployment device having a guide wire catheter extending to a proximal end and a trigger wire and trigger wire release mechanism adapted to retain the proximal end of a prosthesis distally of the proximal end, the trigger wire release mechanism comprising a duct along at least part of the length of the guide wire catheter, the duct having at least one lumen for a trigger wire and an aperture in the duct adjacent the proximal end for the trigger wire to exit the duct to engage the prosthesis, a stent of the prosthesis or a suture retaining the prosthesis to thereby retain the prosthesis.
- 8. A prosthesis deployment device as in claim 7 wherein the device includes a region in which the prosthesis is retained and the duct extends along at least part of the region.
- 9. A prosthesis deployment device as in claim 7 wherein the duct is coaxial with and surrounding the guide wire catheter.
- 10. A prosthesis deployment device as in claim 7 wherein the duct has three lumens for trigger wires.
- 11. A prosthesis deployment device as in claim 7 wherein the duct is formed by a concentric tube around the guide wire catheter and crimped thereto.
- 12. A prosthesis deployment device as in claim 7 wherein the duct is formed by a V shape cross section component retained to the guide wire catheter.
- 13. A prosthesis deployment device having a deployment catheter extending to a proximal end with an elongate region of the catheter in which a prosthesis is retained and a trigger wire and trigger wire release mechanism adapted to retain the proximal end of the prosthesis distally of the proximal end, the trigger wire release mechanism comprising a trigger wire guide along at least part of the length of the region, the duct having at least one lumen for a trigger wire and an aperture in the duct adjacent the proximal end to enable the trigger wire to exit the duct.
- 14. A prosthesis deployment device as in claim 13 wherein the trigger wire guide has three lumens for trigger wires.
- 15. A prosthesis deployment device as in claim 13 wherein region includes a guide wire catheter and the trigger wire guide is coaxial with and surrounding the guide wire catheter.
- 16. A prosthesis deployment device as in claim 15 wherein the trigger wire guide is formed by a concentric tube around the guide wire catheter and crimped thereto.
