The present technology is a prosthetic heart valve device, and related systems and methods, for treating a native valve of a human heart having a native annulus and native leaflets. One embodiment comprises a valve support, a prosthetic valve assembly within the valve support, and an anchoring member. The device further includes an extension member coupled to the anchoring member and having an annular first portion coupled to the anchoring member and a second portion coupled to the first portion. The extension member is folded in a delivery configuration such that the first portion overlaps the second portion. When released from the a delivery catheter, the extension member unfolds such that the first portion extends radially outwardly from the anchoring member and the second portion extends radially outwardly from the first portion.

Prosthetic heart valve devices and associated systems and methods

Devices, systems, and methods for crimping a medical device are disclosed. More specifically, the present disclosure relates to devices, systems, and methods for reducing the diameter of a collapsible heart valve prosthesis to be loaded onto a delivery device. The devices, systems, and methods using at least one funnel to crimp the heart valve prosthesis and load it onto the delivery system.

Devices and methods for crimping a medical device

The present technology is a prosthetic heart valve device, and related systems and methods, for treating a native valve of a human heart having a native annulus and native leaflets. One embodiment comprises a valve support, a prosthetic valve assembly within the valve support, and an anchoring member having an upstream portion and a downstream portion. The device further includes an extension member coupled to the fixation frame and extending radially outward therefrom. The extension member includes a plurality of wires, at least a portion of which include an inner core surrounded by an outer material. The wires include a plurality of recesses extending through at least a portion of the thickness of the outer material, and a therapeutic agent in the recesses for delivery to the anatomy when the prosthetic heart valve device is positioned at a native annulus.

A delivery system for percutaneously delivering a heart valve prosthesis to a site of a native heart valve includes a delivery catheter and a heart valve prosthesis. The delivery catheter includes an outer sheath, an inner shaft, and an orifice restriction mechanism. The heart valve prosthesis has a valve member and a docking member. When the orifice restriction mechanism is positioned within the docking member within an annulus of the native heart valve, the orifice restriction mechanism temporarily replicates the operation of the native heart valve until the valve member is positioned within the docking member.

Delivery systems having a temporary valve and methods of use

A delivery device for delivery and deployment of a heart valve prosthesis with a torque anchoring mechanism includes a balloon having a shaped surface configured to engage a corresponding shaped surface of the heart valve prosthesis. The balloon is configured to rotate about a central longitudinal axis of the delivery device to rotate the heart valve prosthesis.

Heart valve prostheses including torque anchoring mechanisms and delivery devices for the heart valve prostheses

Numerous delivery devices for delivery of a stented prosthesis, such as a stented prosthetic heart valve. Various delivery devices include a capsule that is advanced proximally to retain the stented prosthesis, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper or bumper assembly to provide a smooth transition of the capsule over the stented prosthesis. In some alternate disclosed embodiments, the bumper further serves to connect various elements of the inner shaft assembly. Additional embodiments include a bumper assembly arranged and configured to longitudinally expand and contract to substantially fill any open space as the capsule is retracted from the stented prosthesis, which prevents kinking in the capsule. Additional embodiments include proximal and/or distal bumpers for temporarily covering and smoothing the ends of the stented prosthesis as part of a delivery device that does not include a capsule.

Stented prosthesis delivery system having a bumper

Methods of transcatheter delivery of a prosthetic heart valve. A distal region of a guide member assembly is advanced into a heart of a patient. The distal region is docked to native anatomy of the heart. A delivery device, including a collapsed prosthetic heart valve, is advanced over the docked guide member assembly. The collapsed prosthetic heart valve is located at an implantation site. The prosthetic heart valve is deployed from the delivery device, and then the delivery device is removed from the patient. At least a portion of the guide member assembly is removed from the patient. In some embodiments, the docking structure is docked to one or more of native mitral valve leaflets, chordae in the left ventricle, or walls of the left ventricle as part of a transseptal mitral valve delivery procedure.
