Publication number: 20240261100Abstract: A method of repairing a heart valve provides intravascular access for repair of a heart valve through a ventricular trans-septal approach. An external guide catheter can be inserted through a vein of a patient into the right ventricle via the right atrium. An internal guide catheter can be inserted through the external guide and can provide access to the septum for a puncture tool to create an opening through the septum to the left ventricle. The internal guide can then be advanced into the left ventricle and used to guide a deployment catheter that deploys a repair device onto the heart valve.Type: ApplicationFiled: April 19, 2024Publication date: August 8, 2024Inventors: John Zentgraf, David J. Parins, Arun Saini

Publication number: 20190133766Abstract: Improved methods and apparatuses for heart valve repair in a beating heart of a patient utilize an exchangeable heart valve repair system. Heart valve repair system can include a port adapted to be seated in the heart wall and an imaging catheter slidable within the port. The imaging catheter can be selectively locked relative to the port for insertion into the heart and unlocked once the port is seated to allow the imaging catheter to move distally towards target tissue. A deployment catheter slidably disposed in the imaging catheter and a repair cartridge slidably disposed in the deployment catheter can be used to capture the target tissue and deploy a repair device into the tissue after proper capture is confirmed. System elements can be selectively removed from and replaced within port to deploy additional repair devices while port maintains a seal while elements are and are not inserted.Type: ApplicationFiled: November 15, 2018Publication date: May 9, 2019Inventors: John Zentgraf, David Joseph Parins, Arun Saini

Publication number: 20190053902Abstract: Methods and apparatus for heart valve repair utilize a heart valve repair device including a generally annular ring-like structure and a net structure. The ring-like structure is seated in the valve annulus with the net structure extending from the ring-like structure through the coaptation zone between leaflets. The net structure can then be anchored to a heart structure with a suture. Net structure extending between leaflets helps prevent prolapse of leaflets and can aid in coaptation.Type: ApplicationFiled: September 21, 2018Publication date: February 21, 2019Inventors: John Zentgraf, David Joseph Parins, Arun Saini, Giovanni Speziali

Patent number: 7842010Abstract: A pneumatically-operated thrombectomy catheter deployment system having a plurality of components collectively acting as a drive unit, including a double-acting air cylinder, a reciprocating assembly including a positionable four-way valve, a high pressure pump, an effluent pump, a compressed air tank, and other closely related components. The double-acting air cylinder is reciprocatingly driven by the complement of the drive unit components to provide high pressure saline for use in the thrombectomy catheter and to exhaust effluent from the system. A plurality of preconnected components are connected to the drive unit including a thrombectomy catheter, a saline supply bag, an effluent collection bag, connection tubes, and other closely related components.Type: GrantFiled: December 5, 2005Date of Patent: November 30, 2010Assignee: MEDRAD, Inc.Inventors: Michael John Bonnette, Arun Saini, Ernest Ralph Scherger, III, Eric Joel Thor, Stephen Earl Weisel
