Methods and devices for delivering a ventricular stent
First Claim
1. A method of treating a heart, the method comprising the steps of:
- placing a guidewire through an anterior wall and a posterior wall of a coronary vessel and through a heart wall between a heart chamber and the coronary vessel;
advancing catheter carrying a stent along the guidewire through the anterior wall and the posterior wall of the coronary vessel and into the heart wall; and
expanding the stent within the heart wall.

Abstract
A method, and related tools for performing the method, of delivering a stent or other like device to the heart to connect the left ventricle to the coronary artery to thereby supply blood directly from the ventricle to the coronary artery may be used to bypass a total or partial occlusion of a coronary artery. The method may include placing a guide device and a dilation device through an anterior wall and a posterior wall of the coronary vessel and through a heart wall between the heart chamber and the coronary vessel. The dilation device may be used to form a passageway in the heart wall at a location defined by the guide device. The method may then include placing a stent within the passageway.

53. A method of treating a heart, the method comprising:
-
inserting a needle through an anterior wall and a posterior wall of a coronary vessel;
after inserting the needle, piecing a guidewire through the needle past the anterior wall and the posterior wall of the coronary vessel and through a heart wall between a heart chamber and the coronary vessel;
inserting an expansion device along the guidewire through the anterior wall and the posterior wall of the coronary vessel and into the heart wall;
expanding the expansion device within the heart wall to form a passageway between the heart chamber and the coronary vessel; and
placing a stent within the passageway. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73)
