Methods and devices for delivery of prosthetic heart valves and other prosthetics
First Claim
1. An apparatus for delivering a prosthetic device to a treatment location within a patient, comprising:
- a delivery device comprising proximal and distal ends, the distal end of the delivery device being adapted to carry a prosthetic device and comprising a nose member, the delivery device also comprising an inner shaft and an outer sheath, the inner shaft being coupled to a first deployment member located at or near the distal end of the delivery device, and the outer sheath being coupled to a second deployment member located at or near the distal end of said delivery device,wherein the first deployment member comprises a plurality of elongate structures each having a free end portion engaged with one of a plurality of sockets located within the nose member, the plurality of elongate structures each being slidable out of engagement with the respective one of the plurality of sockets;
wherein the outer sheath and the inner shaft are configured to cause the first deployment member to rotate relative to the second deployment member.

Abstract
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 minimally invasive surgical procedures. The preferred delivery device includes a catheter having a deployment mechanism attached to its distal end, and a handle mechanism attached to its proximal end. A plurality of tethers are provided to selectively restrain the valve during deployment. A number of mechanisms for active deployment of partially expanded prosthetic valves are also described.
