Cardiopulmonary catheter system
First Claim
Patent Images
1. A system for employing blood management during cardiac surgical procedures comprising at least:
- a. an aortic occlusion catheter designed for percutaneous introduction into a peripheral vessel and for antegrade introduction of cardioplegia solution into the coronary arteries, said aortic occlusion catheter being advantageously positioned in the ascending aorta, and further providing a balloon positioned at the base of the ascending aorta just cephalid to the junction of the coronary arteries, said balloon providing for occlusion of the ascending aorta upon inflation;
b. a femoral access arterial return catheter designed for percutaneous introduction into a femoral artery, said femoral access arterial return catheter positioned within a femoral artery and extended slightly therein to facilitate perfusion of the body with oxygenated blood, and terminating in a flexible tip comprising at least one exit hole designed to deter expulsive oxygenated blood flow therefrom; and
c. a femoral access venous return catheter designed for percutaneous introduction into a femoral vein, said femoral access venous return catheter terminating in a flexible tip comprising a plurality of inlet openings to accommodate venous blood drainage from a right atrium.

Abstract
A catheter system for use in minimally invasive cardiac surgical procedures. The catheter system diminishes certain trauma generally associated with invasive cardiac procedures while providing aortic occlusion, extracorporeal circulation, cardiac arrest, and cardiac venting. The catheter system provides a minimally invasive and simplified system that performs total cardiopulmonary bypass with ease of insertion, improved whole body profusion, and shortened recovery periods. The catheters are refined, with reduced diameters and specialized functions for maximum control of each aspect of cardiopulmonary bypass.

14. A method for employing blood management during cardiac surgical procedures comprising the steps of:
-
a. inserting an aortic occlusion catheter comprising a flexible tip, an inflatable balloon positioned at the base of the ascending aorta just cephalid to the junction of the coronary arteries, and at least one infusion outlet positioned proximal to said balloon, into a peripheral vessel; i. advancing the aortic occlusion catheter until the tip abuts the aortic semilunar valve, ii. pulling back on the aortic occlusion catheter such that the tip is just proximal to the coronary arteries and said inflatable balloon is positioned in the ascending aorta, iii. inflating said inflatable balloon to occlude the ascending aorta, iv. arresting the heart utilizing antegrade infusion of cardioplegia solution, and v. venting the left heart; b. inserting a femoral access arterial return catheter comprising a flexible tip including at least one exit hole designed to deter expulsive oxygenated blood flow therefrom into a femoral artery; c. inserting a femoral access venous return catheter comprising a flexible tip including a plurality of inlet openings for accommodating venous blood drainage from the right atrium into a femoral vein; and d. initiating cardiopulmonary bypass. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
