  • Patent number: 11974919
    Abstract: Delivery devices for delivery of a stented prosthetic heart valve. Various delivery devices include an outer sheath assembly including an outer sheath connected to a capsule that is advanced proximally to retain the prosthetic valve, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper to provide a smooth transition of the capsule over the prosthetic valve during loading and recapture procedures. The bumper is expandable from a first position to a second position in which a distal end of the bumper is expanded to increase its diameter. The bumper can be biased in the second, expanded position so that the bumper automatically transitions to the expanded position upon retraction of the outer sheath.

  • Patent number: 11963872
    Abstract: Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a covering feature associated with the spindle for selectively covering at least a portion of a stented prosthetic heart valve tethered to the spindle in a delivery state. In some embodiments, the covering feature includes a tip mounted to the spindle. The tip can include an overhang region for selectively covering a portion of the stented prosthetic heart valve. In other embodiments, the tip can include a tip body and a compressible foam bumper. In yet other embodiments, the covering feature includes an outer sheath arranged to selectively cover the stented prosthetic heart valve. The outer sheath can be elastic and stretchable for recapturing a partially expanded prosthesis, for example by including one or more windows covered by a stretchable covering layer.

  • Publication number: 20240016605
    Abstract: 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.

  • Patent number: 11622857
    Abstract: A catheter based balloon enabled prosthetic heart valve delivery device is provided. The balloon enabled delivery device is configured to deploy a prosthetic heart valve through inflation. The balloon enabled delivery device is further configured to reduce or prevent migration of the prosthetic heart valve during deployment. Migration is prevented through a combination of balanced inflation of the balloon, inflation fluid flow balancing structures, retention rings, retention covers, and balloon surface treatments.
