Patent number: 11247076Abstract: Apparatus and methods for creating tissue necrosis include an energy delivery apparatus that can be positioned adjacent a target treatment site such as a vessel without direct contact with the treatment site tissue. Collimated energy is then directed to the vessel to create necrotic regions in the tissue. Exemplary use in renal vessels creates necrotic regions in adjacent nerves which can alleviate hypertension in a patient.Type: GrantFiled: March 28, 2019Date of Patent: February 15, 2022Assignee: Auris Health, Inc.Inventors: Michael J. Pederson, Patrick J. Phillips, John P. Madden, Michael J. Horzewski

Publication number: 20160331434Abstract: Tissue ablation systems and methods for creating ablation zones in tissue comprises locating a target tissue and positioning an interventional catheter adjacent the target tissue. The interventional catheter has an energy source. Collateral tissue adjacent the target tissue is located. The target tissue is ablated with energy from the energy source so as to form a continuous lesion or region of ablation in the target tissue. The ablating is conducted so as to minimize ablating or otherwise damaging the collateral tissue and to increase the likelihood of procedure success.Type: ApplicationFiled: May 11, 2016Publication date: November 17, 2016Inventors: Patrick Phillips, John P. Madden, Nicholas Patronik, Michael J. Horzewski

Publication number: 20160317843Abstract: A system for ablating and mapping tissue comprises a stand alone tissue ablation system adapted to ablate the tissue, and a stand alone cardiac mapping system adapted to map the tissue. The ablation system is operably coupled with the cardiac mapping system such that mapping data from the cardiac mapping system is provided to the ablation system to create a graphical display of the tissue and the ablation system position relative to the tissue. Motion of the ablation system may be monitored and adjusted based on feedback provided by ablation system actuators as well as position sensors.Type: ApplicationFiled: April 13, 2012Publication date: November 3, 2016Applicant: VytronUS, Inc.Inventors: James W.

Patent number: 8343174Abstract: Devices and methods are provided for tissue approximation and repair. Fixation devices comprise a pair of elements each having a first end, a free end opposite the first end, and an engagement surface therebetween for engaging the tissue, the first ends being moveable between an open position wherein the free ends are spaced apart and a closed position wherein the free ends are closer together with the engagement surfaces generally facing each other. The fixation devices include a locking mechanism coupled to the elements for locking the elements in place. The devices and methods find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions. The invention is particularly useful in 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.Type: GrantFiled: September 4, 2009Date of Patent: January 1, 2013Assignee: Evalve, Inc.Inventors: Eric A. Goldfarb, Jaime E. Sarabia, Alfred H. Raschdorf, John P. Madden

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.
