    摘要: An apparatus for treating cardiovascular diseases includes an expandable support member having oppositely disposed proximal and distal end portions and a main body portion between the end portions for positioning in a blood vessel. The proximal end portion of the expandable support member includes a plurality of wing members that extend from the main body portion. Each of the wing members is for engaging at least a portion of an antrum of a cardiac chamber surrounding the blood vessel. At least a portion of the expandable support member is treated with at least one therapeutic agent for eluting into the blood vessel, the cardiac chamber, and/or cardiac tissue. The expandable support member is made of wire-mesh, and at least a portion of the expandable support member may be made of a bioabsorbable material.

    摘要: An erodible prosthesis comprising alternate rates of erosion is disclosed, wherein said alternate rates of erosion can be selectively initiated. Some embodiments according to the invention may comprise an agent for initiating an alternative rate of erosion, such as, for example, a sensitizer, dissolution inhibitor, photo-acid generator, biochemically active additive, thermally activated catalyst, light activated catalyst, electromagnetic radiation activated catalyst, hydration activated catalyst, pH activated catalyst, low melting agent, and/or enzyme activated catalyst. One or more of the foregoing agents may be dispersed within one or more layers.
