A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.

Systems, devices and methods for transcatheter valve delivery

Valve retainers and delivery systems with valve retainers are disclosed. In certain embodiments, a portion of the valve retainer can rotate about a central axis of the delivery system relative to a different portion of the valve retainer. In certain embodiments, a first portion of the valve retainer can include a plurality of first orientation markings. In certain embodiments, a second portion of the valve retainer can include a second orientation marking, which can be aligned with a first orientation marking on the first portion of the valve retainer.

Clocking valve retainer

A machined or molded hinge design, for use with a delivery device, which allows for controlled deflection of a large diameter catheter. With embodiments in which the delivery device is employed to implant a prosthetic heart valve, deflection of the catheter allows for central alignment of the delivery system in the native annulus during deployment of the bioprosthesis.

Hinged transcatheter prosthetic heart valve delivery system

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 invention features modular implantable ventricular assist devices configured to be, at least in part, assembled within a patient. The devices generally include a pump assembly and an expandable frame. The frame is configured to engage tissue of a patient when implanted. The pump assembly is configured to be operably coupled to the frame when the frame is implanted and in the expanded configuration.

Modular implantable ventricular assist device

A crimping tool includes a housing portion defining a funnel segment and a suture locking mechanism positioned to lock sutures therein. One or more sutures can be coupled with a prosthesis and secured to the suture locking mechanism. The suture locking mechanism can be operated to draw the prosthesis through the funnel segment.
