Patent number: 11701226Abstract: Apparatus and methods are described herein for various embodiments of a prosthetic heart valve, delivery apparatus and delivery methods for delivering a prosthetic heart valve to a heart of a patient via a transapical or transvascular delivery approach. In some embodiments, a prosthetic heart valve includes an outer frame coupled to an inner frame and the outer frame is movable between a first configuration relative to the inner frame and a second inverted configuration relative to the inner frame. The valve can be delivered to a heart using an apparatus that includes a delivery sheath that defines a lumen that can receive the prosthetic heart valve therein when the outer frame is in the inverted configuration. Actuation wires are releasably coupled to the outer frame and can be used to help revert the outer frame after the valve is deployed outside of the delivery sheath and within the heart.Type: GrantFiled: May 13, 2021Date of Patent: July 18, 2023Assignee: Tendyne Holdings, Inc.Inventors: Zachary J. Tegels, Zachary Vidlund, Robert M. Vidlund

Patent number: 11439507Abstract: Apparatus and methods are described herein for use in the delivery of a prosthetic mitral valve. In some embodiments, an apparatus includes a tether fixer assembly configured to engage an outside surface of a heart to secure a prosthetic heart valve in position within the heart. The fixer assembly defines a lumen configured to receive therethrough a tether extending from the prosthetic valve and a movable portion. The fixer assembly is movable between a first configuration, in which the movable portion is disengaged with the tether, and a second configuration in which the movable portion is engaged with the tether. The fixer assembly can be disposed against an epicardial pad positioned on the outside surface of the heart when in the second configuration to secure the prosthetic valve, the epicardial pad and tether in a desired position within the heart.Type: GrantFiled: May 13, 2019Date of Patent: September 13, 2022Assignee: Tendyne Holdings, Inc.Inventors: Preston James Huddleston, Zachary Vidlund

Patent number: 11191639Abstract: Apparatus and methods are described herein for various embodiments of a prosthetic heart valve that have a tether securement feature that can be used to secure an anchoring tether to the prosthetic heart valve such that the tether can maintain the prosthetic heart valve in a desired position within the heart under high tensile forces applied to the tether during functioning of the heart. In some embodiments the tether securement feature can also include an engagement member that can be used to help position the prosthetic heart valve within a heart. Such an engagement member can be matingly engaged by a positioning device that can be used to help in radial positioning of the prosthetic heart valve during delivery and deployment of the prosthetic heart valve.Type: GrantFiled: August 23, 2018Date of Patent: December 7, 2021Assignee: Tendyne Holdings, Inc.Inventors: Zachary Vidlund, Igor Kovalsky

Patent number: 11006939Abstract: In some embodiments, an apparatus includes an introducer sheath and a dilator. The introducer sheath can include a body portion and a tip portion. The body portion can be coupled to the tip portion via a seal portion. The dilator can be configured to be inserted into a lumen defined by the introducer sheath such that the dilator can engage with the tip portion and translate the tip portion relative to the body portion such that the tip portion moves the seal portion from a biased neutral configuration to an extended configuration for delivery of the apparatus to a location in a patient's body. The seal portion can have a larger outermost diameter in the neutral configuration than in the extended configuration.Type: GrantFiled: December 7, 2018Date of Patent: May 18, 2021Assignee: Tendyne Holdings, Inc.Inventor: Zachary Vidlund

Patent number: 10786351Abstract: 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: GrantFiled: June 19, 2017Date of Patent: September 29, 2020Assignee: Tendyne Holdings, Inc.Inventors: Mark Christianson, Zachary Vidlund, Robert Vidlund, Igor Kovalsky, William Peckels, Michael Evans, Chad Perrin, John F.
