Abstract: Disclosed is a system for delivering self-expanding stents to stenting sites within the body, which minimizes trauma to the affected tissue of the patient yet, at the same time, offers the medical practitioner a robust and simple system for stent placement. These technical effects are achieved by providing a catheter which receives the stent at its proximal end and guides it to the stenting site. The catheter serves as a guide catheter and has a tapered distal tip from which the stent emerges at the site of stenting. A stent pusher can be used which abuts the proximal end of the stent inside the guide catheter. The tapered tip can be molded and can be integral with the catheter shaft or bonded to it. The guide catheter can include a figurated portion towards its distal tip. The system has particular application to stenting the carotid artery.

Abstract: A stent delivery catheter for rapid exchange carries at its distal end a sleeve (12) to surround a self-expanding stent (10) and a tension wire (30) running the length of the catheter to release the stent by proximal withdrawal of the sleeve. A tubular catheter shaft (62) surrounds the tension wire. An inner catheter (44) defines a guidewire lumen (48) with a proximal guidewire exit part (58) at the distal end of the catheter shaft. The inner catheter carries an abutment (32) to restrain the stent from moving proximally when the sleeve is pulled proximally. There is a gap (74) between the abluminal surface of the inner catheter and the luminal surface of the catheter shaft, in which the tension wire is accommodated.

Abstract: A catheter system (1) which is useable as a part of a delivery kit for introducing objects (8) into the living body is provided which has a very high flexibility with simultaneous kink resistance and via which compressive as well as tensile forces are reliably transmittable. It comprises at least one longitudinally extended inner catheter (4) and at least one accessory component (6, 10) which is arranged in the distal end region of the inner catheter (4), wherein the end-face is abutted on at least a portion of the accessory component (10) such that movement of the accessory component (10) relative to the longitudinal extent of the inner catheter (4) is prevented.
