Abstract: An elongate member (207) is coated with a coating (209), preferably by co-extrusion, and the coated elongate member (207) is wound in a helical manner around a mandrel (213). The coated elongate member (207) preferably has a square cross-sectional shape so that adjacent portions of the coated elongate member (207) engage one another when the coated elongate member (207) is wound around the mandrel (213). The coated elongate member (207) is then heated so that the coating (209) on adjacent portions of the coated elongate member (207) fuse together to form an integral structure. Another layer (225) of material may be provided on the radially inner or outer wall of the coated elongate member (207).

Abstract: A device (876A) for anchoring a catheter (960) to a cannula (850) is configured to displace the catheter (960) a predetermined amount relative to the cannula (850), and lock the catheter (960) to the cannula (850). The device (876A) may be used with any catheter and a specific application is for the endo-aortic occlusion catheter (960). Another device for anchoring an aortic occlusion balloon includes a clamp (503) positionable around a portion of the ascending aorta. The balloon (401) may also have surface features (407) which help prevent migration of the balloon (401).

Abstract: Devices and methods are provided for temporarily inducing cardio-plegia arrest in the heart of a patient, and for establishing cardiopulmonary bypass in order to facilitate surgical procedures onthe heart and its related blood vessels. Specifically, a catheterbased system is provided for isolating the heart and coronary blood vessels of a patient from the remainder of the arterial system(850), and for infusing a cardio-plegia agent into the patient's coronary arteries to induce cardio-plegia arrest in the heart. The system includes an endo-aortic partitioning catheter (10) having an expandable balloon (11, 161) at its distal end, which is expanded within the ascending aorta (12, 157) to occlude the aortic lumen between the coronary ostia and the brachio-cephalic artery. Means for centering the catheter tip (330) within the ascending aorta include specially curved shaft configurations (1600), eccentric (710) or shaped (792) occlusion balloons (161, 350), and a steerable catheter tip (145) which may be used separately or in combination. The shaft of the catheter may have a coaxial (106) or multilumen (602) construction.

Abstract: This invention is a coronary shunt (800B) for occluding both sides of an anastomosis site, and providing a blood flow path across the anastomosis site. The shunt includes two occluding members (802B) sized and configured to occlude the coronary artery. A tether (808) is attached to the coronary shunt, and is used to remove the coronary shunt from the coronary artery before completing the anastomosis.
