Publication number: 20120065464Abstract: 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: September 14, 2010Publication date: March 15, 2012Applicant: Evalve, Inc.Inventors: Kristin Ellis, Kent D. Dell

Publication number: 20110307055Abstract: 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: August 24, 2011Publication date: December 15, 2011Applicant: ABBOTT VASCULARInventors: Eric A. GOLDFARB, Kent D. DELL, Sylvia Wen-Chin FAN, Brian B. MARTIN, Ferolyn T. POWELL, Alfred H. RASCHDORF, Troy L. THORNTON

Publication number: 20110066233Abstract: Disclosed are devices and methods for treating regurgitation through a valve in the heart. The devices can include an expandable, fluid-tight bladder configured to be deployed between valve leaflets of the heart valve. The bladder can include an upper portion that extends into the atrium of the heart; a lower portion that extends into the ventricle of the heart; and a middle portion positionable within the line of valve leaflet coaptation that provides a sealing surface for one or more of the leaflets.Type: ApplicationFiled: January 19, 2010Publication date: March 17, 2011Inventors: Troy L. Thornton, Eric A. Goldfarb, Kent D. Dell, Jaime E. Sarabia, Steven A. Tyler, Kristin E. Ellis, Jayanth Chakravarthy

Publication number: 20110004227Abstract: Devices, systems and methods are provided for tissue approximation and repair at treatment sites, particularly in those procedures requiring minimally-invasive or endovascular access to remote tissue locations. Fixation devices are provided to fix tissue in approximation with the use of distal elements. In some embodiments, the fixation devices have at least two distal elements and an actuatable feature wherein actuation of the feature varies a dimension of the at least two distal elements. In other embodiments, the fixation devices have at least two pairs of distal elements wherein the pairs of distal elements are moveable to engage tissue between opposed pairs of distal elements. Systems are also provided having fixation devices and accessories.Type: ApplicationFiled: September 15, 2010Publication date: January 6, 2011Applicant: Evalve, Inc.Inventors: Eric A.

Publication number: 20100298929Abstract: Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.Type: ApplicationFiled: January 19, 2010Publication date: November 25, 2010Inventors: Troy L. Thornton, Ferolyn T. Powell, Eric A. Goldfarb, Jan Komtebedde, Kent D. Dell, Pedro B. Lucatero, Francisco J. Valencia, Murli Srinivasan, Roger A. Goodgion, Sandra Saenz, Sylvia Erickson, Sylvester B.

Publication number: 20100217283Abstract: 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. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.Type: ApplicationFiled: May 4, 2010Publication date: August 26, 2010Applicant: 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 Wen-Chin Fan, Eric A. Goldfarb, Kent D. Dell, Ferolyn T. Powell
