The stent comprises a cylindrical wall formed by meshed wires and a covering layer of elastic material extending on a portion of its length, with an outer surface, and totally embracing the wire mesh.

Methods for applying a covering layer to a stent

When installed in the device, the endoprosthesis is compressed radially and located in a cylindrical chamber (14), one proximal area (A) of this endoprosthesis lies within a first outer catheter (3) and a second distal area (B) is in a second outer catheter (30). In order to release the endoprosthesis (1) in a vessel (11), for example, the second outer catheter (30) is first retracted. The endoprosthesis (1) is then held in the first outer catheter (3) by friction and can be re-folded and thus repositioned by advancing the second outer catheter (30). Finally, the endoprosthesis (1) is released by retracting the first outer catheter (3). Because the friction is distributed over at least two outer catheters (3, 30), even endoprostheses (1) that generate a high level of friction on the outer catheter, for example because of a coating, of greater expansion force, or because of great length, can be released.

Apparatus for releasing a self-expanding endoprosthesis

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.

Stent delivery device and method for manufacturing same

The coated stent comprises a cylindrical wall formed by meshed wires and a covering layer of elastic material extending on a portion of its length, with an outer surface, and totally embracing the wire mesh. Method of coating the stent using a lifting medium and then an elastomeric composition dissolved in solvent are disclosed.
