Abstract
A medical device for releasing expandable prostheses in a proximal to distal direction includes an elongate catheter, a flexible sleeve, and an expandable prosthesis. In one embodiment, the distal end of the flexible sleeve is disposed about the distal end of the elongate catheter. In order to deploy the expandable prosthesis, the flexible sleeve is pulled proximally through the lumen of the elongate catheter to expose the expandable prosthesis. An outer sheath and prosthesis retaining line may also be provided to allow the device to release an expandable prosthesis in the distal to proximal direction, or to allow the recapture of the expandable prosthesis after the flexible sleeve is fully withdrawn into the lumen of the elongate catheter.
