Abstract:
1. A device for releasing a self-expanding stent in a vessel of the body, comprising: a tubular sheath which, in a distal section, keeps the stent radially compressed, a pusher element which is guided in the tubular sheath, in order to stabilize the stent when the tubular sheath is pulled back, a handle, with a passage via which the pusher element is secured on a grip, 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; a movable element which is arranged movably over the rod, distally from the handle, and whose movement in a proximal direction allows the tubular sheath to be pulled back, wherein the movable element has an actuating means by which the movable element can be moved step by step in relation to the rod, and wherein the actuating means comprises a lever grip and at least one thrust element which is connected via a first end to the lever grip and which at its second end is designed to engage in the depressions between the elevations of the rod in such a way that a movement of the movable element in the distal direction is blocked; and a carrier coupled to the movable element, said carrier being mounted axially movably within the tubular rod and connected to the movable element in the axial direction with a force fit, wherein the tubular sheath is coupled to the movable element via said carrier.
