Patent number: 11096782Abstract: Prosthetic heart valves are described herein that can provide clearance to the left ventricle outflow tract (LVOT), reduce the possibility of undesirable outflow gradients, and/or limit or prevent LVOT obstructions when implanted in the heart. In some embodiments, a prosthetic heart valve can include an outer frame having a cuff portion that is disposed at an angle (e.g., 80 degrees) relative to the vertical axis of a body portion of the outer frame, so that the prosthetic valve can seat securely in the annulus while not obstructing the ventricular outflow tract of the heart. In some embodiments, a prosthetic heart valve can alternatively, or additionally, include subvalvular components having a short profile, such that the prosthetic valve can seat securely in the annulus while not obstructing the ventricular outflow tract of the heart.Type: GrantFiled: May 29, 2018Date of Patent: August 24, 2021Assignee: Tendyne Holdings, Inc.Inventors: Mark Christianson, Michael Evans, Robert M.

Publication number: 20210244536Abstract: A side-deliverable prosthetic heart valve includes an outer frame and a flow control component. The outer frame defines a central channel that extends along a central axis. The flow control component is disposed within the central channel and coupled to the outer frame. The flow control component has a set of leaflets mounted within an inner frame. The prosthetic valve is configured to be folded along a longitudinal axis and compressed along the central axis to place the prosthetic valve in a compressed configuration for delivery via a delivery catheter. The longitudinal axis is substantially parallel to a lengthwise axis of the delivery catheter when disposed therein. The prosthetic valve transitions to an expanded configuration when released from the delivery catheter. The flow control component elastically deforms from a substantially cylindrical configuration to a substantially flattened configuration when the prosthetic valve is placed in the compressed configuration.Type: ApplicationFiled: April 5, 2021Publication date: August 12, 2021Applicant: VDyne, Inc.Inventors: Mark Christianson, Robert Vidlund, Neelakantan Saikrishnan, Chad Perrin

Publication number: 20200345487Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.Type: ApplicationFiled: July 20, 2020Publication date: November 5, 2020Applicant: Tendyne Holdings, Inc.Inventors: Mark Christianson, Zachary R.
