Apparatus and method for treating cardiovascular diseases
First Claim
1. A method for treating a cardiovascular disease, said method comprising the steps of:
- providing an apparatus comprising an expandable support member having oppositely disposed proximal and distal end portions and a main body portion extending between the end portions, the proximal end portion comprising a plurality of wing members extending from the main body portion, at least a portion of the expandable support member being treated with at least one therapeutic agent for eluting into a blood vessel;
inserting the expandable support member into the pulmonary vasculature;
advancing the expandable support member to a bifurcation in the pulmonary vasculature, the bifurcation comprising the intersection of a first pulmonary blood vessel, a second pulmonary blood vessel, and third pulmonary blood vessel; and
securing the expandable support member within the bifurcation so that the wing members engage a portion of the vessel wall in both the second and third pulmonary blood vessels;
wherein the at least one therapeutic agent elutes into the pulmonary vasculature to treat the cardiovascular disease;
wherein the cardiovascular disease is selected from the group consisting of arrhythmias, heart failure, acute and chronic heart transplant rejection, and pulmonary arterial hypertension.

Abstract
A method is provided for treating a cardiovascular disease, such as pulmonary arterial hypertension, an arrhythmia, or heart failure. One step of the method includes providing an apparatus. The apparatus includes an expandable support member having oppositely disposed proximal and distal end portions and a main body portion extending between the end portions. The proximal end portion includes a plurality of wing members extending from the main body portion. At least a portion of the expandable support member is treated with at least one therapeutic agent for eluting into a blood vessel. The expandable support member is inserted into the pulmonary vasculature and then advanced to a bifurcation in the pulmonary vasculature. The bifurcation includes the intersection of a first pulmonary vessel, a second pulmonary vessel, and a third pulmonary vessel. The expandable support member is secured at the bifurcation to treat pulmonary arterial hypertension, for example.

13. A method for treating a cardiovascular disease, said method comprising the steps of:
-
providing an apparatus comprising an expandable support member having oppositely disposed proximal and distal end portions and a main body portion extending between the end portions, the proximal end portion comprising a plurality of wing members extending from the main body portion, at least a portion of the expandable support member being treated with at least one therapeutic agent for eluting into an atrial chamber and/or cardiac tissue; inserting the expandable support member into an atrial appendage, the atrial appendage having an ostium surrounded by an antrum of the atrial chamber, the atrial appendage being structurally and physiologically distinct from the atrial chamber; and securing the expandable support member in the atrial appendage. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for treating a cardiovascular disease, said method comprising the steps of:
-
providing an apparatus comprising an expandable support member and an electrical mechanism coupled to the expandable support member, the expandable support member having oppositely disposed proximal and distal end portions and a main body portion extending between the end portions, the proximal end portion comprising a plurality of wing members extending from the main body portion, at least a portion of the expandable support member being treated with at least one therapeutic agent for eluting into a blood vessel, the electrical mechanism for delivering electrical energy to at least a portion of the ostium of a pulmonary blood vessel to ablate tissue; inserting the expandable support member into the pulmonary vasculature; advancing the expandable support member to a bifurcation in the pulmonary vasculature, the bifurcation comprising the intersection of a first pulmonary blood vessel, a second pulmonary blood vessel, and third pulmonary blood vessel; and securing the expandable support member within the bifurcation so that the wing members engage a portion of the vessel wall in both the second and third pulmonary blood vessels; wherein the at least one therapeutic agent elutes into the pulmonary vasculature to treat the cardiovascular disease; wherein the cardiovascular disease is selected from the group consisting of arrhythmias, heart failure, acute and chronic heart transplant rejection, and pulmonary arterial hypertension. - View Dependent Claims (22)
