US Patent:

7749266, Jul 6, 2010

Filed:

Feb 27, 2006

Appl. No.:

11/364715

Inventors:

David C. Forster - Los Altos Hills CA, US
Scott Heneveld - Whitmore CA, US
Brandon Walsh - Syracuse UT, US
Brian Beckey - Woodside CA, US

Assignee:

AorTx, Inc. - Los Altos Hills CA

International Classification:

A61F 2/24

US Classification:

623 211

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.

International Classification:

A61B 8/14

US Classification:

600466, 600437, 600467, 623 11, 623 13, 623 124, 623 21, 623900, 623901, 623902, 623903, 623904, 623910, 623913

Abstract:

Devices for assessing the size, shape, and topography of vessel lumens and hollow portions of organs are described. The devices 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 combination thereof.

International Classification:

A61F 2/24

US Classification:

623 218, 623 238

Abstract:

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.

International Classification:

F16D 3/50

US Classification:

464 78, 464149

Abstract:

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.
