Patent number: 7213601Abstract: A method of treatment of congestive heart failure comprises the steps of introducing an aortic occlusion catheter through a patient's peripheral artery, the aortic occlusion catheter having an occluding member movable from a collapsed position to an expanded position; positioning the occluding member in the patient's ascending aorta; moving the occluding member from the collapsed shape to the expanded shape after the positioning step; introducing cardioplegic fluid into the patient's coronary blood vessels to arrest the patient's heart; maintaining circulation of oxygenated blood through the patient's arterial system; and reshaping an outer wall of the patient's heart while the heart is arrested so as to reduce the transverse dimension of the left ventricle.Type: GrantFiled: September 17, 2003Date of Patent: May 8, 2007Assignee: Heartport, IncInventors: John H. Stevens, Lee R. Bolduc, Stephen W. Boyd, Brian S. Donlon, Hanson S. Gifford, III, Philip R. Houle, Daniel C. Rosenman

Patent number: 7017581Abstract: Surgical methods and instruments are disclosed for performing port-access or closed-chest coronary artery bypass (CABG) surgery in multivessel coronary artery disease. In contrast to standard open-chest CABG surgery, which requires a median sternotomy or other gross thoracotomy to expose the patient's heart, port-access CABG surgery is performed through small incisions or access ports made through the intercostal spaces between the patient's ribs, resulting in greatly reduced pain and morbidity to the patient. In situ arterial bypass grafts, such as the internal mammary arteries and/or the right gastroepiploic artery, are prepared for grafting by thoracoscopic or laparoscopic takedown techniques. Free grafts, such as a saphenous vein graft or a free arterial graft, can be used to augment the in situ arterial grafts. The graft vessels are anastomosed to the coronary arteries under direct visualization through a cardioscopic microscope inserted through an intercostal access port.Type: GrantFiled: October 19, 2001Date of Patent: March 28, 2006Inventors: Stephen W. Boyd, Alan R. Rapacki, Matthias Vaska, Brian S. Donlon, William S. Peters

Patent number: 6913600Abstract: Devices and methods are provided for temporarily inducing cardioplegic arrest in the heart of a patient and for establishing cardiopulmonary bypass in order to facilitate surgical procedures on the heart and its related blood vessels. Specifically, a catheter based system is provided for isolating the heart and coronary blood vessels of a patient from the remainder of the arterial system and for infusing a cardioplegic agent into the patient's coronary arteries to induce cardioplegic arrest in the heart. The system includes an endoaortic partitioning catheter having an expandable balloon at its distal end which is expanded within the ascending aorta to occlude the aortic lumen between the coronary ostia and the brachiocephalic artery. Means for centering the catheter tip within the ascending aorta include specially curved shaft configurations, eccentric or shaped occlusion balloons and a steerable catheter tip, which may be used separately or in combination.Type: GrantFiled: September 25, 1998Date of Patent: July 5, 2005Assignee: Heartport, Inc.Inventors: Kirsten L. Valley, David W. Snow, Timothy C. Corvi, Brian S. Donlon, Stephen W. Boyd, Sylvia W. Fan, Alex T. Roth, William S. Peters, Richard J. Mueller, Jr., Hanson S. Gifford, III

Publication number: 20040073301Abstract: Systems and methods are disclosed for performing less-invasive surgical procedures within the heart. A method for less-invasive repair or replacement of a cardiac valve comprises placing an instrument through an intercostal access port and through a penetration in a wall of a vessel in communication with the heart, advancing the instrument into the heart, and using the instrument to perform a surgical intervention on a cardiac valve in the heart under visualization through an intercostal access port The surgeons hands are kept outside of the chest during each step.Type: ApplicationFiled: September 15, 2003Publication date: April 15, 2004Inventors: Brian S.

Patent number: 6645197Abstract: An apparatus for minimizing the risk of air embolism includes an instrument delivery member 2 having a gas outlet 38 for delivering gas into a patient's thoracic cavity. The gas is directed across an opening 48 in the instrument delivery member 2 to help retain the gas in the patient's thoracic cavity. The gas is preferably carbon dioxide which is more soluble in blood than air which will thereby decrease the likelihood of the patient receiving an embolism due to trapped air in the patient's heart and great vessels after surgery.Type: GrantFiled: June 1, 2001Date of Patent: November 11, 2003Assignee: Heartport, Inc.Inventors: Michi E.

Patent number: 6564805Abstract: Devices and methods are provided for less-invasive surgical treatment of cardiac valves whereby the need for a gross thoracotomy or median sternotomy is eliminated. In one aspect of the invention, a delivery system for a cardiac valve prosthesis such as an annuloplasty ring or prosthetic valve includes an elongated handle configured to extend into the heart through an intercostal space from outside of the chest cavity, and a prosthesis holder attached to the handle for releasably holding a prosthesis. The prosthesis holder is attached to the handle in such a way that the holder, prosthesis and handle have a profile with a height smaller than the width of an intercostal space when the adjacent ribs are unretracted, preferably less than about 30 mm.Type: GrantFiled: July 18, 2002Date of Patent: May 20, 2003Assignee: Heartport, Inc.Inventors: Michi E.
