DEVICE AND METHOD FOR TREATMENT OF HEART VALVE REGURGITATION

摘要

A method of treating a mitral valve without open-heart surgery is disclosed. An expandable prosthesis comprises an anchoring portion and an occluding member coupled to the anchoring portion. The prosthesis is loaded into a distal end of a delivery catheter and advanced through a femoral vein and through a pre-made puncture in an atrial septum. The occluding member is then positioned in the mitral valve and the anchoring portion is positioned in the left atrium for maintaining the occluding member between the leaflets of the mitral valve. After deployment, the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole.

1. A method of treating a mitral valve without open-heart surgery, comprising:
loading a prosthesis within a delivery catheter, the prosthesis including an anchoring portion and an occluding member for preventing blood flow in one direction; advancing the delivery catheter through a femoral vein and into a right atrium; passing the delivery catheter through a pre-made puncture in an atrial septum and into the left atrium; advancing the delivery catheter toward a mitral valve; positioning the occluding member between leaflets of the mitral valve; and deploying a portion of the anchoring portion in a left atrium for maintaining the position of the occluding member between the leaflets of the mitral valve, the anchoring portion contacting a mitral annulus; wherein the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole.
