Publication number: 20230149161Abstract: Apparatus and methods are described herein for anchoring a prosthetic heart valve. In some embodiments, an apparatus includes a tether attachment member that includes a base member that defines at least a portion of a tether passageway through which a portion of a tether extending from a prosthetic heart valve can be received therethrough. The base member defines a locking pin channel that intersects the tether passageway. A locking pin is disposable within the locking pin channel and movable between a first position in which the locking pin is at a spaced distance from the tether passageway, and a second position in which the locking pin intersects the tether passageway and can engage the portion of a tether disposed therein to secure the tether to the tether attachment member.Type: ApplicationFiled: January 19, 2023Publication date: May 18, 2023Applicant: Tendyne Holdings, Inc.Inventors: Robert M.

Patent number: 11589985Abstract: Apparatus and methods are described herein for use in the transfemoral delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when 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 delivery sheath is inserted into a femoral vein and moved through the femoral vein and a septum of a heart until a distal end of the delivery sheath is disposed in the left atrium of the 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. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.Type: GrantFiled: December 27, 2018Date of Patent: February 28, 2023Assignee: Tendyne Holdings, Inc.Inventors: Robert M. Vidlund, Mark Christianson, Igor Kovalsky

Publication number: 20230000626Abstract: 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: September 13, 2022Publication date: January 5, 2023Applicant: Tendyne Holdings, Inc.Inventors: Mark Christianson, Chad Perrin, Zachary Tegels, Craig Ekvall, Robert Vidlund, Son Mai, Michael Evans

Publication number: 20220409369Abstract: A prosthetic valve includes a frame and a flow control component. The frame has an aperture extending through the frame about a central axis. The flow control component is mounted within the aperture and is configured to permit blood flow in a first direction approximately parallel to the vertical axis from an inflow end to an outflow end of the flow control component and to block blood flow in a second direction, opposite the first direction. The frame has an expanded configuration with a first height along the central axis, a first lateral width along a lateral axis perpendicular to the central axis, and a first longitudinal length along a longitudinal axis perpendicular to the central axis and the lateral axis. The frame has a compressed configuration with a second height less than the first height and a second lateral width less than the first lateral width.Type: ApplicationFiled: February 28, 2022Publication date: December 29, 2022Applicant: VDyne, Inc.Inventors: Mark CHRISTIANSON, Robert VIDLUND, Neelakantan SAIKRISHNAN

Publication number: 20220395370Abstract: 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: March 7, 2022Publication date: December 15, 2022Applicant: VDyne, Inc.Inventors: Robert VIDLUND, Chad PERRIN, Neelakantan SAIKRISHNAN, Mark CHRISTIANSON

Publication number: 20220323212Abstract: A side-deliverable prosthetic valve includes an outer frame, a flow control component mounted within the outer frame, and an anchoring element coupled to a distal side of the outer frame. The prosthetic valve is foldable along a longitudinal axis and compressible along a central axis to a compressed configuration for side delivery via a delivery catheter and is expandable to an expanded configuration when released from the delivery catheter. An end portion of the anchoring element is configured to engage a guide wire. The anchoring element is extended during deployment to allow the anchoring element to capture at least one of native leaflet or chordae and, in response to the guide wire being disengaged from the end portion, transitions to a folded configuration to secure at least one of the native leaflet or the chordae between the anchoring element and the distal side of the outer frame.Type: ApplicationFiled: November 15, 2021Publication date: October 13, 2022Applicant: VDyne, Inc.Inventors: Robert VIDLUND, Mark CHRISTIANSON, Scott KRAMER

Publication number: 20220280296Abstract: A side-deliverable prosthetic heart valve includes an outer frame and a flow control component. The outer frame has a supra-annular region, a subannular region, and a transannular region therebetween. The flow control component is mounted to the outer frame such that at least a portion of the flow control component is disposed in the transannular region. The prosthetic valve has a delivery configuration for side-delivery via a delivery catheter and is expandable when the prosthetic valve is released from the delivery catheter. The subannular region of the outer frame is disposable in a first configuration as the prosthetic valve is seated in an annulus of a native heart valve and is transitionable to a second configuration after the prosthetic valve is seated in the annulus of the native heart valve.Type: ApplicationFiled: May 23, 2022Publication date: September 8, 2022Applicant: VDyne, Inc.Inventors: Mark CHRISTIANSON, Robert VIDLUND, Neelakantan SAIKRISHNAN, Scott KRAMER, Chad PERRIN, Lucas HARDER
