Publication number: 20130338764Abstract: 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: May 28, 2013Publication date: December 19, 2013Inventors: Troy L. THORNTON, Eric A. GOLDFARB, Kent D. DELL, Jaime E. SARABIA, Steven A. TYLER, Kristin ELLIS, Jayanth CHAKRAVARTHY

Publication number: 20130282059Abstract: 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: March 28, 2013Publication date: October 24, 2013Applicant: EVALVE, INC.Inventors: Ted KETAI, Chris BENDER, Steven A. TYLER, Troy L. THORNTON, Eric A. GOLDFARB

Patent number: 8409273Abstract: Devices, systems, methods and kits are provided for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by a multi-catheter guiding system which is positioned in a desired configuration, generally directed toward the target tissue. Interventional devices may then be passed through the guiding system to the target tissue. Depending on the location of the target tissue and the desired angle of approach, the guiding system may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. The multi-catheter guiding system of the present invention comprises an outer guiding catheter and a coaxially positioned inner guiding catheter, each of which independently form curvatures so that together the curves properly direct the interventional device.Type: GrantFiled: October 30, 2007Date of Patent: April 2, 2013Assignee: Abbott Vascular IncInventors: Troy L. Thornton, Brian B. Martin, Amy R. Raatikka, Yen C. Liao, William D. Kolosi, Pedro Lucatero

Patent number: 8216256Abstract: 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: GrantFiled: February 26, 2009Date of Patent: July 10, 2012Assignee: Evalve, Inc.Inventors: Alfred H. Raschdorf, Jr., Troy L. Thornton, Theodore W. Ketai

Patent number: 8123703Abstract: The present invention provides devices, systems, methods and kits for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by an access sheath which is positioned in a desired configuration, generally directed toward the target tissue. Depending on the location of the target tissue and the desired angle of approach, the access sheath may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. In addition, the access sheath has a locking feature to hold the sheath in place and maintain the desired configuration. Interventional devices may then be passed through the sheath to the target tissue.Type: GrantFiled: February 3, 2010Date of Patent: February 28, 2012Assignee: Evalve, Inc.Inventors: Brian B. Martin, Amy R. Raatikka, Troy L. Thornton, Ferolyn T. Powell

Publication number: 20120010461Abstract: Devices, systems and methods are provided for stabilizing and grasping tissues such as valve leaflets, assessing the grasp of these tissues, approximating and fixating the tissues, and assessing the fixation of the tissues to treat cardiac valve regurgitation, particularly mitral valve regurgitation.Type: ApplicationFiled: September 22, 2011Publication date: January 12, 2012Applicant: ABBOTT VASCULAR INC.Inventors: Eric A. GOLDFARB, Troy L. THORNTON, Alfred H. RASCHDORF, Jaime E. SARABIA, John P. MADDEN, Ferolyn T. POWELL, Brian B. MARTIN, Sylvia WEN-CHIN FAN, Jan KOMTEBEDDE, Yen C. LIAO

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

Patent number: 7981139Abstract: The present invention provides apparatuses, systems, methods and kits for fastening sutures or similar devices used in medical surgical procedures. In particular, the present invention is suitable for use with percutaneous or minimally invasive procedures in which sutures are placed with catheter-based devices wherein the tying of knots is particularly challenging. Suture fasteners of the present invention provide for fastening the sutures together in a fixed position at any location along the suture strands. In addition, the fasteners are adjustable to allow repositioning of the fastener after placement to a new desired location along the suture strands. Similarly, such fasteners may be used to hold a single suture strand for various applications.Type: GrantFiled: April 11, 2006Date of Patent: July 19, 2011Assignee: Evalve, IncInventors: Brian B.
