Publication number: 20210236112Abstract: Apparatus and methods are described herein for repositioning a tether attached to a prosthetic heart valve. In some embodiments, a method includes inserting a distal end portion of a snare device through an incision at a first location in a ventricular wall of a heart and within the left ventricle of the heart. A tether extending from a prosthetic mitral valve, through the left ventricle and out an incision at a second location on the ventricular wall of the heart is snared with the snare device. The tether is pulled with the snare device such that a proximal end of the tether is moved back through the incision at the second location on the ventricular wall and into the left ventricle. The snare device is pulled proximally such that the tether is pulled proximally through the incision at the first location in the ventricular wall of the heart.Type: ApplicationFiled: April 20, 2021Publication date: August 5, 2021Applicant: Tendyne Holdings, Inc.Inventors: Robert M.

Publication number: 20210186693Abstract: A delivery system for side-delivery of a prosthetic valve includes a compression device defining a lumen having a first perimeter at a proximal end that is larger than a second perimeter of the lumen at a distal end. A loading device is coupleable to the compression device and defines a lumen having substantially the second perimeter. A distal end of the loading device includes a first gate that is movable between an open state and a closed state to at least partially occlude the lumen of the loading device. A delivery device defines a lumen having substantially the second perimeter. A proximal end of the delivery device is coupleable to the distal end of the loading device and includes a second gate movable between an open state and a closed state to at least partially occlude the lumen of the delivery device.Type: ApplicationFiled: March 5, 2021Publication date: June 24, 2021Applicant: VDyne, Inc.Inventors: Robert VIDLUND, I, Mark Christianson, Neelakantan Saikrishnan, Scott Kramer, Chad Perrin, Lucas Harder, David Holtan, Craig Ekvall, Cameron Vidlund

Publication number: 20200246143Abstract: Apparatus and methods are described herein for use in the delivery and deployment of a prosthetic mitral valve into a heart. In some embodiments, an apparatus includes a catheter assembly, a valve holding tube and a handle assembly. The valve holding tube is releasably couplable to a proximal end portion of the catheter assembly and to a distal end portion of the handle assembly. The handle assembly includes a housing and a delivery rod. The delivery rod is configured to be actuated to move distally relative to the housing to move a prosthetic heart valve disposed within the valve holding tube out of the valve holding tube and distally within a lumen of the elongate sheath of the catheter assembly. The catheter assembly is configured to be actuated to move proximally relative to the housing such that the prosthetic valve is disposed outside of the lumen of the elongate sheath.Type: ApplicationFiled: April 23, 2020Publication date: August 6, 2020Applicant: Tendyne Holdings, Inc.Inventors: Craig A.

Publication number: 20200163765Abstract: A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.Type: ApplicationFiled: January 30, 2020Publication date: May 28, 2020Applicant: Tendyne Holdings, Inc.Inventors: Mark Christianson, Chad Perrin, Zachary Tegels, Craig Ekvall, Robert Vidlund, Son Mai, Michael Evans

Publication number: 20200113696Abstract: Apparatus and methods are described herein for positioning an epicardial anchor device and measuring the load of a tether extending from a prosthetic heart valve and coupled to the epicardial anchor device. In some embodiments, an apparatus includes a handle assembly coupled to an elongate member and a docking member coupled to a distal end of the elongate member. The docking member can be releasably coupled to an epicardial anchor device configured to secure a tether extending from a prosthetic heart valve implanted with a heart at a location on an exterior of a ventricular wall of the heart. A force sensor device is coupled to the handle assembly and can measure a force exerted on the force sensor device. The force is associated with a tension of the tether extending through the elongate member and handle assembly.Type: ApplicationFiled: November 12, 2019Publication date: April 16, 2020Inventors: Craig A.
