Prosthetic valves and their component parts are described, as are prosthetic valve delivery devices and methods for their use. The prosthetic valves are particularly adapted for use in percutaneous aortic valve replacement procedures. The delivery devices are particularly adapted for use in minimall

대표청구항 ▼

1. An apparatus for delivering a prosthetic heart valve to a body lumen, comprising: a delivery catheter comprising a tube and a gripper, the tube having a plurality of slots and the gripper having a plurality of fingers;a prosthetic heart valve having a support structure comprising a plurality of folded panels and being coupled, in a contracted state, with the gripper;wherein relative rotation between the tube and the gripper causes the plurality of folded panels to move through and radially extend outward from the plurality of slots of the tube,wherein longitudinal movement of the gripper relative to the tube causes the folded panels to slide out of the slots, andwherein relative motion between the gripper and the prosthetic heart valve causes the prosthetic heart valve to be released from the fingers of the gripper. 2. The apparatus of claim 1, wherein the prosthetic heart valve is biased to revert to the expanded state after release from the gripper. 3. The apparatus of claim 1, further comprising an expansion member for expansion of the prosthetic heart valve after release from the gripper. 4. The apparatus of claim 3, wherein the expansion member is a mesh member. 5. The apparatus of claim 3, wherein the expansion member comprises a balloon. 6. The apparatus of claim 1, further comprising a sheath slidable over the slots of the tube. 7. The apparatus of claim 1, wherein the gripper is an elongate member defining a longitudinal axis, and each of the plurality of fingers extends from a first end of the gripper generally parallel to the longitudinal axis. 8. The apparatus of claim 1, further comprising a handle located at a proximal end of the delivery catheter, the handle adapted to control the relative rotation and the longitudinal motion of the tube and the gripper. 9. The apparatus of claim 1, wherein the gripper is slidably and rotatable received within the tube. 10. The apparatus of claim 1, wherein the delivery catheter comprises an atraumatic nosecone configured to enhance the ability of the delivery catheter to pass through vasculature of the patient. 11. An apparatus for delivering a prosthetic heart valve to a body lumen, comprising: a delivery catheter comprising a tube and gripper, the tube having a plurality of slots and the gripper having a plurality of fingers;a prosthetic heart valve having a support structure comprising a plurality of folded panels and being coupled, in a contracted state, with the gripper;wherein relative rotation between the tube and the gripper causes the plurality of folded panels to move through and radially extend outward from the plurality of slots of the tube,wherein longitudinal movement of the gripper relative to the tube causes the folded panels to slide out of the slots,wherein relative motion between the gripper and the prosthetic heart valve causes the prosthetic heart valve to be released from the fingers of the gripper, andwherein the tube comprises only three slots, the gripper comprises only three fingers, and the prosthetic heart valve comprises only three panels, each panel being metallic.
