COATED PROSTHETIC CARDIAC DEVICE

摘要

The device (10) comprises an orifice ring (12) having an outer periphery and an inner periphery. The ring defines an annulus (13). The annulus defines a passage for the flow of blood. A fabric member is coupled to at least the outer periphery of the orifice ring. The fabric member carrying silver. The fabric is coated with silver in an ion beam-assisted, high-vacuum environment, such that the silver atoms are inserted into the surface of the fabric. The fabric is coated with silver in a high-vacuum environment, such that the silver atoms are coated on the surface of the fabric.
