Abstract
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.
