In surgery, a percutaneous procedure is any medical procedure or method where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an "open" approach where inner organs or tissue are exposed (typically with the use of a scalpel).
Percutaneous Heart Valve Prosthesis
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).

Method and apparatus for percutaneous reduction of anterior-posterior diameter of mitral valve
A method and apparatus for treating mitral regurgitation by approximating the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve. The distal end of the device is inserted into the coronary sinus of the heart and the proximal end of the device rests within the right atrium along the tendon of Todaro and extends to at least the membranous septum of the tricuspid valve. Because the coronary sinus approximates the lateral (posterior) annulus of the mitral valve and the tendon of Todaro approximates the septal (anterior) annulus of the mitral valve, the device encircles approximately one half of the mitral valve annulus. The apparatus is then adapted to deform the underlying structures i.e. the septal annulus and lateral annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation.
