Percutaneous heart valve

ActiveUS20070016286A1Avoid flowStability and functioning of the heart valve are satisfactoryHeart valvesBlood flowValvular prosthesis

A percutaneously inserted bistable heart valve prosthesis is folded inside a catheter for transseptal delivery to the patient's heart for implantation. The heart valve has an annular ring, a body member having a plurality of legs, each leg connecting at one end to the annular ring, claws that are adjustable from a first position to a second position by application of external force so as to allow ingress of surrounding heart tissue into the claws in the second position, and leaflet membranes connected to the annular ring, the body member and / or the legs, the leaflet membranes having a first position for blocking blood flow therethrough and a second position for allowing blood flow therethrough. The heart valve is designed such that upon removal of the external force the claws elastically revert to the first position so as to grip the heart tissue positioned within the claws, thereby holding the heart valve in place. The body member and claws may be integrated into a one-piece design. The heart valve may be used as a prosthesis for the mitral valve, aortic valve, pulmonary valve, or tricuspid valve by adapting the annular ring to fit in a respective mitral, aortic, pulmonary, or tricuspid valve opening of the heart.

ActiveUS20080243245A1Avoid flowStentsHeart valvesProsthesisRight atrium

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).

Heart valve leaflet selection methods and apparatuses which subject individual leaflets to loads and measure the resulting deflection to more reliably group leaflets of similar physical characteristics for later assembly in prosthetic heart valves. The deflection testing may be accomplished using a variety of test set ups which are designed to impart a load on the leaflet which simulates the actual loading within a heart valve. The results from a number of deflection tests are used to categorize individual leaflets, which data can be combined with other data regarding the characteristics of the leaflet to better select leaflets for assembly into a multi-leaflet heart valve. In one embodiment, the deflection test is combined with an intrinsic load test, and leaflets having similar deflection and intrinsic load values used in the same heart valve. One apparatus for testing the leaflets includes a frame for securing the arcuate cusp of the leaflet while the straight coapting edge remains free, to simulate the actual leaflet mounting configuration within the heart valve prosthesis. The frame may include a lower portion having a recess for the leaflet and plurality of receptor holes around the peripheral edge of the recess, and an upper portion having a plurality of needles which extend downward through the leaflet and into the receptor holes and secure the edges of the leaflet.

An instrument for implanting an expandable cylindrical vascular prosthesis includes an outer tube and an inner tube which can be displaced relative to one another. The inner tube is longitudinally slotted on the distal end, at least in an area thereof, and ensheathes the stent with this area which includes the longitudinal slot. In order to implant the stent, the outer tube is retracted. The stent then expands with continuous retracting movement of the outer tube and the inner tube is pressed open along the longitudinal slot. Implantation is terminated, when the outer tube is retracted along the entire length of the stent. The implantation is reversible by pushing the outer tube forward, as long as the stent has not yet fully exited the instrument. In this way, the inner tube is constricted together with the stent, and compressed to an initial position.

The present invention provides devices and methods for the treatment of cardiovascular valve diseases such as aortic stenosis. A vascular valve assembly is formed from two or more valve devices, each of which contains a valve mounted in a stent. The individual valve devices are brought to the site of the defective valve by standard percutaneous catheterization methods. Lateral expansion of the stents at the site of valve replacement produces a functioning valve assembly. Appropriate sizing and number of valve devices prevents regurgitation and migration. The assembly of two or more smaller valve devices at the site of a defective valve prevents complications due to the large size of single valve prostheses.
