An artificial valve for repairing a damaged heart valve having a plurality of cusps separating upstream and downstream regions. The artificial valve includes a flexibly resilient frame with a plurality of peripheral anchors for anchoring the frame in position between the regions. The frame includes a central portion located between the anchors. The valve includes a flexible valve element attached to the central portion of the frame having an upstream side and a downstream side opposite the upstream side. The valve element moves to an open position when fluid pressure in the upstream region is greater than fluid pressure in the downstream region to permit downstream flow. The valve element moves to a closed position when fluid pressure in the downstream region is greater than fluid pressure in the upstream region to prevent flow reversal. The valve may be used in beating heart procedures, avoiding cardiopulmonary bypass and cardioplegia.

An artificial valve for repairing a damaged heart valve having a plurality of cusps separating an upstream region from a downstream region. The artificial valve includes a flexibly resilient frame sized and shaped for insertion in a position between the upstream region and the downstream region. The frame has a plurality of peripheral anchors for anchoring the frame in the position between the upstream region and the downstream region and a central portion located between the plurality of peripheral anchors. The valve also includes a flexible valve element attached to the frame and to the central portion of the frame having an upstream side facing the upstream region when the frame is anchored in the position between the upstream region and the downstream region and a downstream side opposite the upstream side facing the downstream region when the frame is anchored in the position between the upstream region and the downstream region. The valve element moves to an open position when fluid pressure in the upstream region is greater than fluid pressure in the downstream region to permit downstream flow from the upstream region to the downstream region. The valve element moves to a closed position when fluid pressure in the downstream region is greater than fluid pressure in the upstream region to prevent flow reversal from the downstream region to the upstream region.

A heart assist device intended for the long term support of certain late-stage cardiac failure states, particularly those known in the practice of cardiology to be called a dilated cardiomyopathy. A method is described wherein a "viscous cardioplasty jacket" is fashioned to provide a buttressing effect to the ventricular heart walls to thus render a more efficient cardiac contractile mechanism whereby the patient is afforded improved heart function to allow increased physical activities. Such a viscous compliant enclosure of the ventricular heart masses can be utilized concurrently with recognized drug therapy which is sometime lacking in beneficial effect for these patients and is far less traumatic than the currently practiced surgical cardiomyoplasty (CMP) procedure. Application of this device may be accomplished through a relatively non-invasive endoscopic procedure in a more refined methodology of anatomical implantation of the device.
