Abstract
The stent delivery device has an elongated sheath with a self-expandable stent placed in contracted condition within the distal area of the sheath. An elongated core is arranged in the sheath for relative longitudinal motion between core and sheath, and drive means are arranged between the core and the stent. Scratch protection tubular means comprise a reinforcement ring secured in the sheath and surrounding the distal end portion of the stent when the stent is in contracted condition in the sheath and a tube of thermoformable material heat shrunk over the proximal end portion of the stent and over the core.
