Patent number: 9937043Abstract: Embodiments described herein provide devices, systems, and methods that reduce the distance between two locations in tissue, often for treatment of congestive heart failure. For example, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. The anchor may be deployed into the heart through a working lumen of a minimally invasive access tool. The minimally invasive access tool may have a plurality of grippers near a distal end of the working lumen. The grippers may engage epicardial tissue of the heart and may be moved radially inwardly relative so as to provide stabilization of the epicardial tissue and/or hemostasis near an access site where the anchor is inserted through the epicardium. The minimally invasive access tool may minimize blood loss from the access site and improve anchor implant processes.Type: GrantFiled: July 31, 2015Date of Patent: April 10, 2018Assignee: BioVentrix, Inc.Inventors: Kevin Van Bladel, Lon Annest, John Stiggelbout, Rovil Arcia
