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.
