Abstract
An artificial mitral valve is anchored in the left atrium by placing the valve between the annulus of the natural mitral valve and an artificial annulus. The artificial annulus is formed by inserting a tool into the coronary sinus, and adjusting the tool to force the wall of the left atrium to form an annulus above the artificial valve, this locking it in place and forming a hemostatic seal.
Claims16
A device to replicate a function of a natural mitral valve in a left atrium of a heart, at least partially about which natural mitral valve a coronary sinus of said heart extends, the device comprising:
- an artificial mitral valve insertable inside an opening formed by the natural mitral valve in the left atrium of said heart;
- and
- an elongate member having a flexible state and a more rigid state, said elongated member being at least partially insertable into the coronary sinus in the flexible state such that the elongate member at least partially encircles a portion of the artificial mitral valve, and which elongate member forms an artificial annulus in the more rigid state to physically secure the artificial mitral valve in the opening.
A device to replicate a function of a natural mitral valve in a left atrium of a heart, a coronary sinus of the heart forming a path extending at least partially about the natural mitral valve, the device comprising:
- an artificial mitral valve percutaneously insertable inside an opening formed by the natural mitral valve of the heart;
- and
- an elongate member having a flexible state and a more rigid state, the elongated member sized in the flexible state to be received by a catheter for percutaneous insertion in the coronary sinus, which elongate member forms an artificial annulus in the coronary sinus with a dimension that is percutaneously adjustable to physically secure the artificial mitral valve in the opening without any sutures between the artificial mitral valve and the heart.
A device to replicate a function of a natural valve in a heart, the device comprising:
- an artificial valve percutaneously insertable inside an opening formed by the natural valve of the heart;
- an elongate member having a flexible state and a more rigid state, the elongated member sized in the flexible state to be received by a catheter for percutaneous insertion in a blood vessel, which elongate member is percutaneously adjustable to physically secure the artificial valve in the opening without any sutures between the artificial valve and the heart;
- and
- a tool which can be manipulated to adjust the elongate member percutaneously and which is selectively detachable from a portion of the elongate member.
