Abstract
A delivery system for a self-expandable prosthesis includes a catheter having a distal portion and a proximal portion, a balloon portion positioned on the distal portion, and a self expanding medical device positioned about the balloon portion. The medical device has a compressed state and an expanded state. A sheath couples the medical device in its compressed state about the balloon portion and has only a single opening in a wall of the sheath. When the balloon is expanded, the sheath is configured to (i) first rupture at the single opening, thereby allowing the medical device to self-expand and engage an inner wall of a vessel, and (ii) controllably continue the rupturing from the single opening to the proximal end of sheath, thereby allowing the medical device to expand to its expanded state and a portion of the medical device to engage an inner wall of the vessel.
