1. A method of clamping an aorta of a patient for performing a medical procedure, comprising the steps of:
- introducing a clamp positioner having a clamp located at a distal end into a patient;
clamping the clamp around the patient'"'"'s ascending aorta so that a blood flow through the ascending aorta is at least substantially restricted;
disengaging at least the distal end of the clamp positioner from the clamp after the clamping step;
performing a medical procedure on the patient'"'"'s cardiopulmonary system;
releasing the clamp from the patient'"'"'s ascending aorta; and
removing the clamp from the patient.

Abstract
A deployable clamp for clamping a patient'"'"'s ascending aorta between the coronary arteries and the brachiocephalic artery. The clamp is detachably mounted to the distal end of an elongated clamp positioner and is manipulated and actuated from the proximal end of the clamp positioner at a location outside of the patient'"'"'s thoracic cavity. When actuated, the clamp blocks blood flow through the ascending aorta.

8. A method of constricting a hollow body structure in a thoracic cavity of a patient, the method comprising:
-
introducing a clamp into a patient'"'"'s thoracic cavity using a clamp positioner having a proximal end positioned outside of the patient'"'"'s thoracic cavity and a distal end within the patient'"'"'s thoracic cavity; positioning the clamp at a hollow body structure using the clamp positioner; securing the clamp onto the hollow body structure using the proximal end of the clamp positioner to at least partially seal said hollow body structure; disengaging at least a part of the clamp positioner from the clamp; detaching the clamp from the hollow body structure; and removing the clamp from the patient'"'"'s thoracic cavity. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A clamping assembly for constricting an ascending aorta in a thoracic cavity of a patient, the assembly comprising:
-
a clamp having first and second jaws configured to clamp a patient'"'"'s ascending aorta, the first and second jaws having jaw surfaces being movable between open and closed positions, the clamp having a locking mechanism configured to the first and second jaws in the closed position; and a clamp positioner having a distal end releasably coupled to the clamp, the clamp positioner having a clamp actuator configured to move the clamp from the open position to the closed position; the distal end of the clamp positioner and the clamp coupled thereto being configured for introduction into a thoracic cavity of the patient through a percutaneous intercostal penetration in the patient'"'"'s chest. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
