Problems solved by technology

The aortic valve can also suffer from prolapse, and the valves of the venous circulation can suffer from a similar condition, which can lead to chronic venous closure caused by damaged or "incompetent" valves characterized by malcoaptation incomplete

Embodiment Construction

[0079] figure 1 Depicted is a surgically and / or percutaneously deliverable artificial leaflet assist device 100. The artificial leaflet assist device 100 has a device ring 101 and a device body or artificial leaflet 102. The device ring 101 serves as a device for attaching to An anchor for the tissue at or near the cusp or other valve annulus, the device body or the artificial leaflet 102 is used to improve the function of the autogenous (eg, mitral valve) leaflet. The leaflet material can be selected from any of the following: synthetic biocompatible polymers such as polyester or polyurethane, or materials such as pericardium and / or other materials known in the art for implantable valves, etc. Treated natural fixing material. The device ring is usually made of metal (for example, Nitinol) or a polymer such as polyurethane. In some embodiments, such as when the leaflets are composed of natural fixing materials, the leaflets are sutured to the loop. When the leaflet is compos...

Abstract

A prosthetic valve coaptation assist device (100) includes an anchor (101) and a single valve assist leaflet (102). The anchor may be a supporting ring frame, brace or arc structure and will usually be radially self-expandable so that it can expand against surrounding tissue. The valve assist leaflet may be made of pericardium or other biological or artificial material and is shaped like the native target valve leaflet. The valve assist leaflet is typically sized larger than the target leaflet so that after implantation a significant overlap of the device body occurs.
