Endoprosthesis to be implanted with a duodenoscope, especially as transpapillary bile duct drain, in the form of a drainage tube provided with drainage holes in the wall

摘要

The invention relates to an endoprosthesis to be implanted with a duodenoscope, especially as transpapillary bile duct drain, in the form of a drainage tube provided with drainage holes in the wall and, in particular, for improved handling it proposes that the drainage tube (22) which is open at both ends be pushed onto a pilot probe tube (5) having a tensile core (7), the distal end (5') of which tube can be bent into a hooked shape (hook H) by tension on the proximal end of the core (7) and the length of which is greater than twice the length of the duodenoscope, an end piece (10) intended for attachment to a tension operating handle (12) being withdrawable from the proximal end (5") of the pilot probe tube (5) in order to reduce the terminal cross-section to the internal dimensions of a push-on tube (23) which can be pushed onto the pilot probe tube (5) and the front end of which abuts against the rear end of the drainage tube (22).
