Abstract:
1. A delivery system having a release mechanism for releasing an object which is carried by a catheter having a proximal and a distal end, the object at the distal end of the catheter, the release mechanism comprising: at least one outer shaft retractable toward the proximal end of the catheter to release the object, a stationary cutting device which can cut a proximal section of the outer shaft that is moved toward the proximal end of the catheter into at least two pieces, and a winding device comprising a pair of rollers associated with the proximal end of the catheter which winds up the proximal sections of the outer shaft after the proximal sections are cut to retract the outer shaft toward the proximal end of the catheter, at least one of the rollers having an operating element, a spring connecting the operating element with a brake, wherein when the operating element is in a first position, the brake holds an axel of the at least one roller preventing rotation, and wherein when the operating element is in a second position, the brake releases the axel permitting rotation.
