Abstract
The present invention relates to a device for delivering a self-expanding stent in a vessel of the body. The device comprises a tubular sheath which, in a distal section, keeps the stent radially compressed, and a pusher element, which is guided in the tubular sheath, in order to stabilize the stent when the sheath is pulled back. A handle is also provided, with a passage via which the pusher element is secured on the handle. The device further comprises a tubular rod which is fixedly connected to the handle and inside which the pusher element is provided, and which is provided at least in part with regularly spaced elevations and with depressions lying between the elevations. In addition, a movable element is provided which is arranged movably over the rod, distally from the handle, and whose movement in the proximal direction allows the sheath to be pulled back.
