  • Publication number: 20200315787
    Abstract: A method of treating a native mitral valve without open-heart surgery is disclosed. An expandable prosthesis includes an anchoring portion and an occluding member coupled to the anchoring portion. The prosthesis is loaded into a distal end portion of a delivery catheter and is advanced through a femoral vein and through a pre-made puncture in an atrial septum. The anchoring portion self-expands within the left atrium for anchoring the occluding member in a fixed position. The anchoring portion is preferably a laser cut structure that conforms to the left atrium and uniformly distributes anchoring forces within the left atrium. After deployment, the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole. The occluding member is preferably made from a flexible material, such as pericardial tissue.

  • Patent number: 8992605
    Abstract: In one embodiment, the present invention provides a prosthesis that can be implanted within a heart to at least partially block gaps that may be present between the two mitral valve leaflets. In one preferred embodiment, the prosthesis includes an anchoring ring that expands within the left atrium to anchor the prosthesis and a pocket member fixed to the anchoring ring. When the mitral valve is open, blood flows past the pocket member, maintaining the pocket member in a collapsed state. When the mitral valve closes, the backpressure of the blood pushes into the pocket member, expanding the pocket member to an inflated shape. The mitral valve leaflets contact the expanded pocket member, allowing the prosthesis to block at least a portion of the openings between the leaflets, thereby minimizing regurgitated blood flow into the left atrium.

  • Publication number: 20020082684
    Abstract: An intravascular prosthetic graft is provided which includes a flexible tubular body having a first end defining at least one opening and a second end defining at least one opening. The flexible tubular body may be elongated and define a longitudinal axis. A first ring member is connected to the first end adjacent to the at least one opening of the first end. A second ring member is connected to the second end adjacent to the at least one opening of the second end. The flexible tubular body can be fabricated from a flexible material, such as, for example, DACRON®, TEFLON®, or other suitable material. The first and second ring members may be fabricated from a rigid material, such as metals or polymerics. A method of repairing at least a portion of an arterial system, such as, for example, treatment of an aortic aneurysm is disclosed.
