Problems solved by technology

Mitral valve regurgitation can cause dilation of the left heart chambers, which, if not treated, can eventually lead to potentially fatal heart rhythm disturbances and heart failure
Existing methods do not correctly model mitral valve function and do not address underlying issues such as tissue damage, cardiac remodeling, and paravalvular leaks
Furthermore, currently developed technologies do not provide an adequate means for replacing heart valve implants after they have been deployed.

Abstract

Systems (100) and methods are provided for repairing a heart valve, such as a mitral, tricuspid or aortic valve, using an adjustable and removable implant (102) that can be delivered to the heart through the apex in a simplified and non-invasive manner. The implant can include a prosthetic valve portion (106) coupled to a proximal end of a shaft, and an anchor portion (110) coupled to a distal endof the shaft. The prosthetic valve can be suspended within an opening of the heart valve while the anchor portion is affixed to the apex of the heart. When the implant is deployed, a distance betweenthe prosthetic valve portion and the anchor portion can be adjusted, and / or the implant or a portion thereof can be rotated to thereby change the position of the prosthetic valve within the heart valve. This can allow correcting for post-implantation movements of the implant to mitigate potential complications.

Description

[0001] Case Description [0002] This application is a divisional application of the Chinese invention patent application CN201480063220.7 filed on November 20, 2014, entitled "Adjustable Heart Valve Implant". technical field [0003] Systems and methods are provided for repairing a heart valve using an adjustable heart valve implant. Background technique [0004] The human heart is an important part of the body with four chambers, left and right atria and left and right ventricles. Each chamber can alternately expand and contract to pump blood through the body. Each chamber of the heart includes a heart valve, which controls blood flow through the heart in only one direction during normal operation. However, the heart valve can become diseased or have other defects that prevent it from closing properly when the lower chambers contract. [0005] Mitral regurgitation is a type of mitral valve failure in which the mitral valve, which separates the left atrium from the left...
