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

Publication number: 20190175182Abstract: The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.Type: ApplicationFiled: February 14, 2019Publication date: June 13, 2019Applicant: EVALVE, INC.Inventors: Eric A. Goldfarb, Alfred H. Raschdorf, Jaime E. Sarabia, Sylvia Wen-Chin Erickson, Kent D. Dell, Jan Komtebedde, Ferolyn T. Powell

Publication number: 20150223793Abstract: The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.Type: ApplicationFiled: April 28, 2015Publication date: August 13, 2015Applicant: ABBOTT VASCULAR, INC.Inventors: Eric A. GOLDFARB, Kent D.
