Aortic Occlusion Catheter
First Claim
1. A device for occluding a patient'"'"'s ascending aorta, comprising:
- a hub having one or more ports;
an elongated body having opposing proximal and distal ends, the elongated body defining one or more lumens extending at least partially between the proximal and distal ends of the elongated body, and each of the one or more lumens being in fluid communication with at least one of the one or more ports of the hub, wherein the elongated body has a pre-configured, selectively actuated curve profile at least proximate the distal end of the elongated body; and
an expandable member at the distal end of the elongated body, the expandable member being selectively changeable between expanded and contracted states.

Abstract
An cardioplegic fluid delivery catheter includes an expandable member for occluding the ascending aorta of a patient. A length of the catheter allows the distal end to be within the ascending aorta while the proximal end extends from a peripheral artery. The delivery catheter has a multi-lumen construction with a primary lumen extending configured to allow a cardioplegic fluid to be delivered to the aorta. Secondary lumens provide for balloon inflation and aortic root pressure monitoring. The delivery catheter includes a shaft having a pre-determined curve profile at a distal end of the delivery catheter. The pre-determined curve profile generally corresponds to the curve of the bottom surface of the aortic arch. The shaft may be eccentric to the expandable member such that retraction of the shaft causes a distal tip to be parallel within the ascending aorta.

28. A method of delivering antegrade cardioplegic fluid to a heart of a patient, the method comprising:
-
introducing at least a distal end of an antegrade cardioplegic delivery catheter into a peripheral artery of the patient; advancing the distal end of the antegrade cardioplegic delivery catheter from the peripheral artery into an ascending aorta of the heart of the patient, wherein advancing the distal end of the antegrade cardioplegic delivery catheter changing a curve profile of the delivery catheter to a predetermined curve profile configured to generally correspond to a bottom surface of an aortic arch of the patient; occluding the ascending aorta with an occlusion device of the antegrade cardioplegic delivery catheter; positioning a distal tip of the antegrade cardioplegic delivery catheter in a generally parallel alignment within the ascending aorta; and delivering a fluid to the heart through a lumen of the antegrade cardioplegic delivery catheter. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
