ABSTRACT:
A delivery system is provided for releasing a medical device within a body cavity. The delivery system may be used in an intravascular procedure to implant a self-expandable stent. A helical structure on the shaft of the delivery system engages the inner surface of the stent. As a result, the stent may be released by rotating the shaft relative to the stent which pushes the stent forward from the distal end of the shaft.
