Publication number: 20100268020Abstract: 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: July 1, 2010Publication date: October 21, 2010Applicant: BioVentrix (a CHF Technologies, Inc.)Inventors: Sing-Fatt Chin, Lon Annest

Publication number: 20100016655Abstract: 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: ApplicationFiled: July 21, 2009Publication date: January 21, 2010Applicants: Bio Ventrix (a CHF Technologies, Inc.Inventors: Lon S.

Publication number: 20080269551Abstract: Devices, systems, and methods for treating a heart of a patient may make use of one or more implant structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart.Type: ApplicationFiled: February 19, 2008Publication date: October 30, 2008Applicant: BIOVENTRIX (A CHF TECHNOLOGIES, INC. COMPANY)Inventors: Lon S. Annest, Arthur A. Bertolero, Sing-Fatt Chin, David K. Swanson

Patent number: 7441342Abstract: A method for use in reconstructing the left ventricle of the heart of a patient from a diseased state to an appropriate reconstructed state is disclosed. The method includes the steps of determining the body surface area of the patient; determining a characteristic of the left ventricle which is the same in the diseased state as in the reconstructed state; determining an appropriate sizer based on the determined body surface area of the patient and the characteristic of the left ventricle which is the same in the diseased state as in the reconstructed state; identifying akinetic tissue within a heart chamber wall; making an incision through the akinetic tissue in the chamber wall; inserting said appropriate sizer into the chamber through the incision; removing the sizer; and, closing the incision.Type: GrantFiled: April 27, 2005Date of Patent: October 28, 2008Assignee: CHF Technologies, Inc.Inventors: Lon Annest, Rob O'Reilly, Sing-Fatt Chin, Arthur Bertolero

Publication number: 20080097148Abstract: A method for reducing left ventricular volume, which comprises identifying infarcted tissue during open chest surgery; reducing left ventricle volume while preserving the ventricular apex; and realigning the ventricular apex, such that the realigning step comprises closing the lower or apical portion of said ventricle to achieve appropriate functional contractile geometry of said ventricle in a dyskinetic ventricle of a heart.Type: ApplicationFiled: December 20, 2007Publication date: April 24, 2008Applicant: CHF TECHNOLOGIES, INC.Inventors: Sing-Fatt Chin, Arthur Bertolero, Lon Annest

Publication number: 20080082132Abstract: 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 a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart. The implant may include an electrode or other structure for applying pacing signals to one or both ventricles of the heart, for defibrillating the heart, for sensing beating of the heart or the like. A wireless telemetry and control system may allowing the implant to treat congestive heart failure, monitor the results of the treatment, and apply appropriate electrical stimulation.Type: ApplicationFiled: September 28, 2006Publication date: April 3, 2008Applicant: CHF Technologies, Inc., a California corporationInventors: Lon S.
