The present invention relates to apparatus and methods for endovascularly delivering and releasing a prosthesis, e.g., an aortic prosthesis, within and/or across a patient's native heart valve, referred to hereinafter as replacing the patient's heart valve. In some embodiments the delivery system comprises a plurality of first actuatable element adapted to engage a plurality of second elements in a first configuration to capture the implant within the delivery system, and wherein the plurality of first actuatable element are adapted to engage the plurality of second elements in a second configuration and to release the implant from the delivery system.
1. A capturing system adapted to releasably capture a medical implant in a delivery system wherein the delivery system is adapted to deliver the medical implant through a body lumen, the capturing system comprising: a plurality of finger elements; anda plurality of actuatable elements each configure
1. A capturing system adapted to releasably capture a medical implant in a delivery system wherein the delivery system is adapted to deliver the medical implant through a body lumen, the capturing system comprising: a plurality of finger elements; anda plurality of actuatable elements each configured to slidably interface with one of the plurality of finger elements;wherein each of the plurality of actuatable elements is adapted to engage one of the plurality of finger elements in a first position so as to capture a portion of the medical implant, and each of the plurality of actuatable elements is adapted to engage one of the plurality of finger elements in a second position to release the portion of the medical implant from the coupling system;wherein the medical implant comprises an expandable braid. 2. The system of claim 1 wherein the plurality of finger elements and the plurality of actuatable elements are adapted to engage to lock together. 3. The system of claim 2 wherein the plurality of finger elements and the plurality of actuatable elements are adapted to engage to lock in the first position. 4. The system of claim 2 wherein the plurality of finger elements and the plurality of actuatable elements are adapted to engage to lock in the second position. 5. The system of claim 2 wherein the plurality of actuatable elements are adapted to be actuated by a proximally directed force. 6. The system of claim 2 wherein the plurality of actuatable elements are adapted to be actuated to be unlocked from the plurality of finger elements. 7. The system of claim 6 wherein the actuatable element comprises a lock element which is adapted to engage with the finger element to lock them together, the actuatable element further comprising a lock stop element adapted to prevent movement of the lock element after the actuatable element is unlocked from the first position. 8. The system of claim 1 further comprising a plurality of release actuators, wherein the plurality of actuatable elements are adapted to be actuated by the plurality of release actuators. 9. The system of claim 8 wherein the plurality of release actuators comprises a plurality of release actuator arrays. 10. The system of claim 1 wherein the plurality of finger elements comprise an implant interface, and wherein the implant engages with the implant interface in the first position. 11. The system of claim 10, wherein the implant interface is disposed near the distal end of the plurality of finger elements. 12. The system of claim 10 wherein the implant interface comprises a cavity in the finger element adapted to receive the portion of the implant. 13. The system of claim 1 wherein neither the plurality of actuatable elements nor the plurality of finger elements are adapted to be coupled to the portion of the implant. 14. The system of claim 1 wherein the portion of the implant is released from the capturing system as the actuatable element is moved from the first position to the second position. 15. The system of claim 14 wherein the actuatable elements comprise an ejection element adapted to eject the portion of the implant from the finger element while the actuatable element is being moved from the first position to the second position, thus releasing the portion of the implant from the capturing system. 16. The system of claim 15 wherein the ejection element is disposed substantially at the distal end of the actuatable element. 17. The system of claim 1 wherein the capturing system is adapted to assume a first collapsed delivery configuration and a second expanded configuration. 18. The system of claim 17 wherein the plurality of finger elements comprise a restraining device adapted to limit expansion of the capturing system. 19. The system of claim 18 wherein the restraining device passes through each of a set of holes in the plurality of finger elements, thereby coupling the plurality of finger elements and limiting the expansion of the plurality of finger elements.
