Publication number: 20230000619Abstract: This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.Type: ApplicationFiled: September 8, 2022Publication date: January 5, 2023Applicant: Tendyne Holdings, Inc.Inventors: Robert Vidlund, Kemal Schankereli, Lucian Lozonschi, Georg Lutter

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
