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.

Patent number: 10624744Abstract: Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.Type: GrantFiled: February 12, 2018Date of Patent: April 21, 2020Assignee: BioVentrix, Inc.Inventors: Lon S. Annest, Claudio Argento, William Butler, Ernest Heflin

Patent number: 10617525Abstract: Devices, systems, and methods for treating a heart of a patient may make use of structures which limit a size of a chamber of the heart, such as by deploying one or more tensile member to bring a wall of the heart and a septum of the heart into contact. A plurality of tension members may help exclude scar tissue and provide a more effective remaining ventricle chamber. The implant may be deployed during beating of the heart, often in a minimally invasive or less-invasive manner. Trauma to the tissues of the heart may be inhibited by selectively approximating tissues while a pressure within the heart is temporarily reduced. Three-dimensional implant locating devices and systems facilitate beneficial heart chamber volumetric shape remodeling.Type: GrantFiled: March 9, 2018Date of Patent: April 14, 2020Assignee: BioVentrix, Inc.Inventors: Lon S. Annest, Arthur A. Bertolero, David K. Swanson

Patent number: 10617524Abstract: 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: GrantFiled: August 25, 2015Date of Patent: April 14, 2020Assignee: BioVentrix, Inc.Inventors: Kevin Van Bladel, Aaron Weiss, Lon Annest, Gilbert Mata, Jr.

Patent number: 10575953Abstract: According to one embodiment, a heart anchor tensioning device includes a main body and an elongate shaft. A tension member or tether may be inserted through a lumen of the elongate shaft to allow the shaft to be advanced over the tension member and within a body while the main body is positioned outside of the body. The device also includes an anchor coupling mechanism that is configured to engage a heart anchor and move the heart anchor into engagement with a first wall of the heart. The anchor coupling mechanism is able to lock the heart anchor to inhibit proximal movement of the heart anchor along the tension member. The device further includes a tension indicating mechanism that provides an indication of a force being applied to the heart anchor by the device.Type: GrantFiled: August 29, 2014Date of Patent: March 3, 2020Assignee: BioVentrix, Inc.Inventors: Kevin Van Bladel, Lon Annest, Ernest Heflin, Gilbert Mata, Lawrence Crainich, Brian LaRose

Publication number: 20190307564Abstract: A heart implant alignment and delivery device includes an elongate body having an opening that is disposed near a distal end of the elongate body. The opening is configured so that a heart implant is positionable within the opening with the heart implant exposed to a surrounding environment and so that the heart implant is substantially aligned with the distal end of the elongate body. The device also includes an implant reposition member, such as a cable, that is releasably coupleable with the heart implant and that is operationally coupled with the elongate body so that a first operation of the implant reposition member causes the heart implant to be retractably deployed from the opening of the elongate body.

Publication number: 20190274833Abstract: 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: January 8, 2019Publication date: September 12, 2019Applicant: BioVentrix, Inc.Inventors: Kevin Van Bladel, Lon Annest, Murray Sheldon, Ernie Heflin, Andrew Wechsler, John Stiggelbout, Rovil Arcia, John Bower

Patent number: 10219904Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue, often for treatment of congestive heart failure. In one embodiment an anchor of an implant system may reside within the right ventricle in engagement with the ventricular 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 an epicardial surface. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a catheter. An anchor force may be applied within a desired range to secure the anchors about the septum and epicardial surface. The anchor force may inhibit migration of the anchors relative to the septum and epicardial surface.Type: GrantFiled: November 2, 2015Date of Patent: March 5, 2019Assignee: BioVentrix, Inc.Inventors: William Butler, Kevin Van Bladel, Ernie Heflin, Lon Annest, Rovil Arcia, John Bower
