PERCUTANEOUS HEART VALVE PROSTHESIS
First Claim
1. A percutaneous heart valve prosthesis comprising:
- a valve body having a valve body first end, a valve body second end and a passage extending along a longitudinal axis between said valve body first end and said valve body second end, said valve body being collapsible about said longitudinal axis for delivery via catheter; and
one or more flexible valve elements secured to said valve body and extending across said passage for blocking bloodflow in one direction through said passage from said valve body second end to said valve body first end;
a flexible skirt extending about a periphery of said valve body for blocking bloodflow in said one direction between said valve body and the native wall of a valve orifice in use;
wherein said valve body tapers toward said valve body first end, said valve body first end being sized to pass through a valve orifice associated with a heart valve to be replaced, said valve body second end being sized so as not to pass through the valve orifice.

Abstract
A percutaneous heart valve prosthesis (1) has a valve body (2) with a passage (9) extending between the first and second ends (7, 8) of the valve body (2). The valve body (2) is collapsible about a longitudinal axis (10) of the passage (9) for delivery of the valve body (2) via a catheter (18). One or more flexible valve leaflets (3, 4) are secured to the valve body (2) and extend across the passage (9) for blocking bloodflow in one direction through the passage (9). An anchor device (5), which is also collapsible for delivery via catheter (18), is secured to the valve body (2) by way of an anchor line (6). A failed or failing mitral heart valve (101) is treated by percutaneously locating the valve body (2) in the mitral valve orifice (102) with the anchor device (5) located in the right atrium (107) and engaging the inter-atrial septum (103), such that the taught anchor line (6) acts to secure the valve body (2) within the mitral valve orifice (102).
