Publication number: 20220000622Abstract: Embodiments described herein include devices, systems, and methods for reducing the distance between two locations in tissue. In one embodiment, an anchor may reside within the right ventricle in engagement with the septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along a surface of the heart. Perforating the exterior wall and the septum from an epicardial approach can provide control over the reshaping of the ventricular chamber. Guiding deployment of the implant from along the epicardial access path and another access path into and through the right ventricle provides control over the movement of the anchor within the ventricle. The joined epicardial pathway and right atrial pathway allows the tension member to be advanced into the heart through the right atrium and pulled into engagement along the epicardial access path.Type: ApplicationFiled: June 17, 2021Publication date: January 6, 2022Applicant: BioVentrix, Inc.Inventors: Kevin Van Bladel, Lon Annest, Murray Sheldon, Ernie Heflin, Andrew Wechsler, John Stiggelbout, Rovil Arcia, John Bower

Patent number: 10252027Abstract: Transvascular access devices and methods for transvascular access are provided. The transvascular access devices can include a guidewire lumen and a guide tube and stylet disposed in a second lumen. The guide tube can be used to control the orientation of the stylet and provide additional support for the stylet. The methods include providing a second entry point in a vessel of a patient remote from a first entry point. A vascular catheter can enter the vascular system of a patient at a first entry point and be advanced to a second entry point. A guide tube can be advanced out the second lumen of the vascular catheter with a stylet advanced out of the guide tube to pierce the vessel wall and skin of the patient at the second entry point. A catheter can be introduced to the vascular system at the second entry point.Type: GrantFiled: November 23, 2015Date of Patent: April 9, 2019Assignee: Vascular Access Technologies, Inc.Inventors: Lakshmikumar Pillai, Patrick Burt, John Lunsford, John Stiggelbout

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
