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.

Method for delivering a prosthetic heart valve with an expansion member

Prosthetic heart valves, scaffolding structures, and systems and methods for implantation of same

Devices and methods for assessing the size, shape, and topography of vessel lumens and hollow portions of organs are described. The devices and methods are particularly adapted for determining the size, shape, topography, and compliance of the native heart valves to facilitate the later implantation of a prosthetic heart valve. The devices are typically catheter-based having an assessment mechanism fixed to a distal end of the catheter. The assessment mechanism generally includes an expandable member, such as a balloon. The assessment mechanism may also include an imaging member, a physical assessment member, an electronic mapping construction, an alignment mechanism, a valvuloplasty balloon, or any combinations thereof. The methods typically comprise deploying the balloon percutaneously to a target location, expanding the balloon, and determining one or more physical parameters associated with the target location.

Methods of assessing inner surfaces of body lumens or organs

Described herein are systems and methods for operation of a prosthetic valve support structure () having additional reinforcement coupled with panels (). Multiple support members () are distributed across the inner surface of the valve support structure () at regular intervals. Each support member () can include a looped portion () to act as a hinge (). Each looped portion () is in a location coincidental with the interlace between adjacent panels ().

Prosthetic heart valves, support structures and systems and methods for implanting same

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.

Methods and devices for delivery of prosthetic heart valves and other prosthetics

Torque shafts and other related systems and methods are described herein. The torque shafts are both flexible and capable of transmitting torque. The torque shafts are useful for procedures that require torque and pushability to drive or deploy a device. The flexibility and pushability of the torque shafts enable them to curve along a tortuous path, and the torque transferring capability of the shafts enable them to transmit torque along the shaft.

Torque shaft and torque shaft drive

Prosthetic valves implantation methods and systems, especially as related to fitting a prosthetic valve at the site of a native stenotic or incompetent valve are described. The subject devices, systems and associated dock deployment and implant docking techniques may be employed in percutaneous valve replacement procedures.
