Publication number: 20200205976Abstract: A catheter based medical system and medical procedure for reducing cardiac valve regurgitation are disclosed. The system comprises a resilient curvilinear shaped annuloplasty implant for reducing the size of a dilated annulus of said valve for reducing said regurgitation having resilient anchoring elements, and a delivery device for said annuloplasty implant having a distal curvilinear shaped portion that is hollow to mount said annuloplasty implant and has an annular opening arranged to be in apposition against an annulus of said cardiac valve. A plurality of suction units allows for a atrial approach and symmetric implantation of said implant.Type: ApplicationFiled: March 11, 2020Publication date: July 2, 2020Inventor: Anders Jönsson

Publication number: 20200205977Abstract: Prosthetic mitral valves described herein can be deployed using a transcatheter mitral valve delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native mitral valve. This document describes prosthetic heart valve designs that interface with native mitral valve structures to create a fluid seal, thereby minimizing mitral regurgitation and paravalvular leaks. This document also describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. In addition, this document describes prosthetic heart valve designs and techniques that reduce the risk of interference between the prosthetic valves and chordae tendineae.Type: ApplicationFiled: February 25, 2020Publication date: July 2, 2020Inventors: Kavitha Ganesan, Ramji Venkatasubramanian, Andrew T. Forsberg, Cyril J. Schweich, Todd J. Mortier, Erik O. Martz, Douglas J. Krone

Publication number: 20200205978Abstract: The disclosure relates to a device that is configured to be implanted on the native leaflet of a heart valve to increase its length and/or thickness and thereby to improve the valve function and reduce regurgitation. The device may include a leaflet section. The leaflet section may include a central member. The central member may include a first portion, a second portion that opposes the first portion, and a base portion disposed between the first portion and the second portion. The first section may extend from the first portion and the second section may extend from the second portion. The device may include one or more engaging members extending from the central member at an angle with respect to the first section and the second section. The second section may be larger than the first section. The leaflet section may define a three-dimensional region or a bulge.Type: ApplicationFiled: July 23, 2018Publication date: July 2, 2020Inventors: Sai Muralidhar Padala, Eric Leo Sarin

Publication number: 20200205981Abstract: According to one embodiment, a protective device for use in congestive heart failure treatments, and other treatments, includes a control mechanism, an elongate shaft, and a protective plate. The control mechanism is coupled with a proximal end of the elongate shaft and the protective plate is pivotably coupled with a distal end of the elongate shaft. The elongate shaft enables the protective plate to be inserted within a body and navigated distally of a heart wall. The protective plate has a relatively wide and thin body portion and is pivotable relative to the elongate shaft by operation of the control mechanism. Pivoting and/or navigating of the protective plate within the body allows the protective plate to be positioned adjacent the heart wall to shield body organs or tissue surrounding the heart wall from being damaged by surgical instruments inserted through the heart wall.Type: ApplicationFiled: March 10, 2020Publication date: July 2, 2020Applicant: BioVentrix, Inc.Inventors: Kevin Van Bladel, Aaron Weiss, Lon Annest, Gilbert Mata, JR.

Publication number: 20200205982Abstract: Apparatus and methods to reduce ventricular volume are disclosed. The device takes the form of a transventricular anchor, which presses a portion of the ventricular wall inward, thereby reducing the available volume of the ventricle. The anchor is deployed using a curved introducer that may be inserted into one ventricle, through the septum and into the opposite ventricle. Barbs or protrusions along the anchor body combined with a mechanical stop and a sealing member hold the device in place once deployed.Type: ApplicationFiled: March 12, 2020Publication date: July 2, 2020Applicant: BioVentrix, Inc.Inventors: Sing-Fatt Chin, Lon S.
