Patent number: 10327743Abstract: The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. The tissue structures can be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment. In one aspect, a structure is deployed in a gutter region of the valve annulus to modify the shape of the valve.Type: GrantFiled: April 25, 2006Date of Patent: June 25, 2019Assignee: EVALVE, INC.Inventors: Frederick G. St. Goar, James I-Lin Fann, Mark E. Deem, Hanson S. Gifford, III, Martin S. Dieck, Brian B. Martin, Sylvia Wenchin Fan, Eric A. Goldfarb, Kent D. Dell, Ferolyn T. Powell

Patent number: 6932792Abstract: A cardioplegia catheter is configured to extend into the ascending aorta with a proximal portion of the shaft extending into a left chamber of the heart through a aortic valve and out of the heart through a penetration in a wall thereof. The cardioplegia catheter has an occlusion member configured to occlude the ascending aorta between the brachiocephalic artery and the coronary ostia. An arterial return cannula delivers oxygenated blood to the arterial system downstream of the occlusion member, while cardioplegic fluid is delivered through a lumen in the cardioplegia catheter upstream of the occlusion member to induce cardioplegic arrest.Type: GrantFiled: July 17, 2000Date of Patent: August 23, 2005Inventors: Frederick G. St. Goar, John H. Stevens, Hanson S. Gifford, III, Bartley P. Griffith

Patent number: 6913601Abstract: A catheter system is provided for accessing the coronary ostia transluminally from a peripheral arterial access site, such as the femoral artery, and for inducing cardioplegic arrest by direct infusion of cardioplegic solution into the coronary arteries. In a first embodiment, the catheter system is in the form of a single perfusion catheter with multiple distal branches for engaging the coronary ostia. In a second embodiment, multiple perfusion catheters are delivered to the coronary ostia through a single arterial cannula. In a third embodiment, multiple perfusion catheters are delivered to the coronary ostia through a single guiding catheter. In a fourth embodiment, multiple catheters are delivered to the coronary ostia through a single guiding catheter which has distal exit ports that are arranged to direct the perfusion catheters into the coronary ostia.Type: GrantFiled: May 22, 2001Date of Patent: July 5, 2005Assignee: Heartport, Inc.Inventors: Frederick G.

Publication number: 20020151970Abstract: The valve implantation system has a valve displacer for displacing and holding the native valve leaflets open in a first aspect of the invention. A replacement valve may be attached to the valve displacer before or after introduction and may be positioned independent of the valve displacer. In another aspect of the invention, the valve displacer and valve are in a collapsed condition during introduction and are expanded to deploy the valve displacer and valve. The valve is a tissue valve mounted to an expandable support structure. The support structure may have protrusions for engaging the valve displacer or barbs for anchoring the valve displacer to the heart or blood vessel. A temporary valve mechanism may be used to provide temporary valve functions during and after deployment of the valve displacer.Type: ApplicationFiled: June 3, 2002Publication date: October 17, 2002Inventors: Michi E.
