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.
