Assignee:

Edwards Lifesciences CardiAQ LLC - Irvine CA

International Classification:

A61F 2/24

Abstract:

Devices, systems and methods are described for implantation of a prosthesis within a lumen or body cavity and delivery systems for delivering the prosthesis to a location for implantation. A delivery system can include a tether connected to a single directional handle knob for release of the prosthesis within the lumen or body cavity and retraction of the tether towards the handle.

International Classification:

A61F 2/24
A61L 27/36
A61L 27/04

Abstract:

A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

G16H 10/60
A61B 90/00
G16H 40/63

Abstract:

Systems, apparatuses, and methods disclosed herein are provided for a motorized implant delivery system. The delivery system may utilize a processor for control of at least one motor for actuating a delivery apparatus. The delivery system may include sensors configured sense one or more of a condition of the patient's body or a condition of the delivery apparatus. The processor may process the signals provided by the sensors, which may comprise feedback signals to the processor.
