Patent number: 9861475Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets during systole, which, in turn, reduces regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.Type: GrantFiled: August 12, 2009Date of Patent: January 9, 2018Assignee: MVRX INC.Inventors: Timothy R. Machold, David A. Rahdert, John A. Macoviak, Robert T. Chang, Rick A. Soss

Devices, systems, and methods for supplementing, repairing or replacing a native heart valve leaflet
Patent number: 9610161Abstract: An implant for supplementing, repairing, or replacing a native heart valve leaflet or leaflets provides a scaffold, which defines a pseudo-annulus. The implant further has at least two struts in generally oppositely spaced apart positions on the scaffold. The scaffold can be placed in an elastically loaded condition in a heart with the struts engaging tissue at or near the leaflet commissures of a heart valve annulus, to reshape the annulus for leaflet coaptation. The implant further provides a neoleaflet element coupled to the scaffold within pseudo-annulus, to provide a one-way valve function.Type: GrantFiled: September 8, 2011Date of Patent: April 4, 2017Assignee: MVRX, INC.Inventors: John A. Macoviak, Robert T. Chang, David A. Rahdert, Timothy R. Machold, Rick A. Soss -
Publication number: 20120185040Abstract: Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.Type: ApplicationFiled: March 27, 2012Publication date: July 19, 2012Applicant: MVRx, iNC.Inventors: DAVID A. RAHDERT, John A. Macoviak, Timothy R. Machold, Robert T. Chang, Rick A. Soss

Publication number: 20080140190Abstract: An implant is sized and configured to be positioned in a left atrium above the plane of a native mitral heart valve annulus having leaflets. The implant, when deployed, engages a wall of the left atrium above the plane of the native mitral valve annulus to interact with movement of the leaflets of the mitral heart valve to affect mitral heart valve function. The implant is deployed into the left atrium through an intravascular access path that extends from a right atrium through a septum and into a left atrium.Type: ApplicationFiled: October 25, 2007Publication date: June 12, 2008Inventors: John A.
