  • Publication number: 20240180697
    Abstract: Aspects of the disclosure relate to devices and methods for preparing an existing, implanted prosthetic aortic valve for subsequent prosthetic aortic valve implantation. To prepare the existing valve, a valve preparation device is delivered to the valve and valve leaflets are severed either via mechanical cutting or electrodes so that the leaflets cannot obstruct a blood flow path once a prosthetic valve is subsequently implanted within the valve. Similarly, in alternate embodiments, devices and methods of the disclosure can be used for preparing a native aortic valve for delivery and implantation of a prosthetic valve.

  • Patent number: 11957581
    Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.

  • Patent number: 11903828
    Abstract: Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a lateral control feature. The cord is tensioned to crimp the prosthesis to a compressed condition for delivery to a target site. Tension is lessened to allow the prosthesis to self-expand. In a tethered and expanded state in which the prosthesis has self-expanded and is connected to the spindle by the cord, the lateral control feature directs the spindle to a prescribed location relative to the prosthesis appropriate for a functional evaluation of the prosthesis. In some embodiments, the spindle is directed to a center of the prosthesis; in other embodiments, the spindle is held at a commissure of the prosthesis. The lateral control features of the present disclosure assume numerous forms.

  • Patent number: 11737898
    Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.
