AI Technical Summary

Problems solved by technology

Movement places a rhythmic load on the appendages, and with about 100,000 heartbeats per day, the risk of valve rupture, tissue tearing and leakage is magnified

Embodiment Construction

[0140] Throughout the various embodiments shown and described herein, like reference numerals will be used in the drawings to refer to like structures. Accordingly, a corresponding description of these same elements is not required and is generally not included in this written description.

[0141] figure 1 One method of mitral valve surgery is shown that may be used in connection with the various devices, systems and methods disclosed herein. Catheter 10 having a lumen and a distal opening is advanced in a peripheral vein, such as the femoral vein. Here, catheter 10 is advanced up the inferior vena cava and across the interatrial septum into left atrium 12 of heart 14 . The distal tip of the catheter 10 passes through the native mitral valve 16 . The heart 14 also includes a left ventricle 17 having a chordae 18 coupling the mitral valve leaflets 16a, 16b with the papillary muscle 19 . Leaflets 16a, 16b extend from the mitral annulus 16c. Inside the catheter 10, which ma...

Abstract

Methods, devices and systems for anchoring and / or sealing a heart valve prosthesis and, in particular, a mitral valve prosthesis (202). Inflatable elements (204, 206) are used to seal and anchor the mitral valve prosthesis (202) and / or other elements associated with repairing a native mitral valve.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 301,924 (pending) filed March 1, 2016 and U.S. Provisional Patent Application Serial No. 62 / 349,830 (pending) filed June 14, 2016 , the disclosure of which is hereby incorporated by reference. Background technique [0003] Despite considerable efforts, catheter-based repair and replacement of the mitral valve remains a challenge. Aortic valve replacement through catheters has advanced very rapidly. The aortic valve has an annulus that can serve as an anchor for a prosthetic valve positioned inside the native valve. The mitral valve has no natural anchors that can be used to support the valve. Therefore, devices that replace the mitral valve require anchoring or fastening systems to hold the prosthesis in place. This procedure requires delivery of a valve prosthesis and anchoring system. Not surprisingly, the stability of the implan...
