Abstract
An instrument for implanting an expandable cylindrical vascular prosthesis includes an outer tube and an inner tube which can be displaced relative to one another. The inner tube is longitudinally slotted on the distal end, at least in an area thereof, and ensheathes the stent with this area which includes the longitudinal slot. In order to implant the stent, the outer tube is retracted. The stent then expands with continuous retracting movement of the outer tube and the inner tube is pressed open along the longitudinal slot. Implantation is terminated, when the outer tube is retracted along the entire length of the stent. The implantation is reversible by pushing the outer tube forward, as long as the stent has not yet fully exited the instrument. In this way, the inner tube is constricted together with the stent, and compressed to an initial position.
