Apparatus and method for treating cardiovascular diseases
First Claim
1. An apparatus for placement in a blood vessel to treat cardiac arrhythmias, said apparatus comprising:
- an expandable support member having a first mesh-like configuration, wherein at least a portion of the expandable support member is treated with a therapeutic agent;
a plurality of wing members that extend from only a proximal end of said expandable support member, each of said plurality of wing members independently having a second mesh-like configuration, each of said plurality of wing members being radially spaced apart from one another, and each of said plurality of wing members having a free end shaped to conform to a portion of an antrum of a cardiac chamber surrounding the blood vessel to engage with the portion of the antrum of the cardiac chamber surrounding the blood vessel; and
an electrical mechanism coupled to said expandable support member for delivering electrical energy to at least a portion of an ostium of the blood vessel to ablate tissue.

Abstract
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.

20. An apparatus configured to be placed in a blood vessel, said apparatus comprising:
-
an expandable support member comprising a first wire-mesh configuration, wherein at least a portion of said expandable support member is treated with a therapeutic agent; a plurality of wing members extending from a proximal end of said expandable support member, each of said plurality of wing members independently comprising a second wire-mesh configuration different from the first wire-mesh configuration, and each of said plurality of wing members having a free end adapted for engaging a portion of an antrum of a cardiac chamber surrounding the blood vessel, wherein each of the plurality of wing members comprises an arch-shaped perimeter that bounds the second wire-mesh configuration; and an electrical mechanism coupled to said expandable support member for delivering electrical energy to at least a portion of an ostium of the blood vessel to ablate tissue. - View Dependent Claims (21)
