First Claim
Patent Images
1. A catheter system for facilitating epicardial surgery and intracardiac surgery on a beating heart, comprising:
- a first catheter having a shape and structure adapted to draw blood from a left ventricle of the beating heart;
a pump coupled to said first catheter; and
an aortic catheter coupled to said pump having a lumen and structure adapted to return said drawn blood to an aorta of the beating heart at a sufficient rate and pressure to perfuse the heart.

Abstract
A catheter system and method of performing posterior epicardial revascularization and intracardiac surgery on a beating heart. Several catheter systems are provided to achieve a left ventricular isolation and a right ventricular isolation as required to facilitate surgery according to the methods of the present invention. Myocardial infusion is provided in either antegrade or retrograde flow to insure the myocardium meets its oxygen demand.

15. A method of performing epicardial revascularization and intracardiac surgery on a beating heart, the heart having an aorta, an aortic base, aortic valve, left ventricle, right pulmonary vein, left atrial apendage, inferior vena cava, superior vena cava, main pulmonary artery, mitrial valve, and coronary sinus, comprising the steps of:
-
a) drawing blood from the left ventricle using a pump and a first catheter while said heart is beating to obtain a left ventricular isolation; and
b) returning a majority of said drawn blood via said pump to the ascending aorta using an aortic catheter. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
