Patent number: 9144663Abstract: Devices and methods for delivering a sealing element post-implantation of valve prosthesis that functions to occlude or fill gaps present between the valve prosthesis and the native valve tissue, thereby reducing, minimizing, or eliminating leaks there through. In a first method, an injectable material is placed within a native valve sinus to form a sealing element that presses native valve leaflets against an outer surface of a heart valve prosthesis. In a second method, an injectable sealing material or a preformed annular sealing component is positioned between the outer surface or perimeter of a heart valve prosthesis and native heart valve tissue. In a third method, a preformed sealing element or component is placed within a heart valve prosthesis to press the prosthesis against native valve tissue.Type: GrantFiled: October 24, 2012Date of Patent: September 29, 2015Assignee: Medtronic, Inc.Inventors: Sarah Ahlberg, Cynthia Clague, Susan Peterson, Scott Mosher, Karan Punga

Patent number: 8821488Abstract: Device, system and method for ablating tissue of a heart of a patient. The tissue is clamped between a pair of opposing jaws. A portion of the tissue is ablated at a first generally linear position on the tissue by applying ablative energy to two of a plurality of elongate electrodes, each of the two of the plurality of elongate electrodes being coupled in opposing relationship to each other and the pair of opposing jaws, respectively. An effectiveness of the ablation is sensed at a second generally linear position on the tissue with at least one of the plurality of elongate electrodes positioned on one of the pair of opposing jaws. The second linear position on the tissue is laterally distal to the first linear position on the tissue with respect to the atrium of the heart.Type: GrantFiled: May 13, 2009Date of Patent: September 2, 2014Assignee: Medtronic, Inc.Inventors: Mark Stewart, David Francischelli, Jinback Hong, Sarah Ahlberg

Patent number: 8734484Abstract: A method for closing an opening at a target site including bodily tissue including embedding a plurality of self-closing clips into the target site in a spaced apart manner about a perimeter of the opening. Each of the clips has opposing clip ends and an intermediate segment. A flexible tether is coupled to the embedded clips to form a loop about the opening perimeter. A pulling force is applied onto at least one of the loop ends, thereby drawing the perimeter of the opening onto itself to completely close the opening. The loop ends are secured to maintain the target site in a closed state. In some embodiments, the target site is apical cardiac tissue, and the method is performed as part of a trans-apical access procedure.Type: GrantFiled: April 21, 2009Date of Patent: May 27, 2014Assignee: Medtronic, Inc.Inventors: Sarah Ahlberg, Sara Simma, Paul T.

Publication number: 20090299364Abstract: An ablation device for ablating tissue having an outer wall and an inner wall, approximately parallel and concentric with said outer wall, defining an inner fluid chamber and an outer low pressure chamber. Each of the outer wall and the inner wall have an edge defining an open face of the fluid chamber and the low pressure chamber. An ablative element is contained within the fluid chamber. A source of low pressure is coupled to the low pressure chamber. When the edge of the outer wall and the edge of the inner wall contact a surface, the ablation device is at least partially secured to the surface by low pressure created in the low pressure chamber by the source of low pressure. The fluid chamber is at least partially fluidly isolated from the low pressure chamber when the ablation device is at least partially secured to the surface.Type: ApplicationFiled: April 21, 2009Publication date: December 3, 2009Applicant: Medtronic, Inc.Inventors: Kester Batchelor, David Francischelli, Tom Daigle, Dan Haeg, Paul Rothstein, Adam Podbelski, Sarah Ahlberg, Steve Ramberg, Tom Conway
