Abstract
The invention relates to a papillotome for percutaneous endoscopic gastrostomy comprising a front opening (), which is located in a free end region of a catheter () and at the outlet of a first lumen (), a rear opening (), which is further from a free end () than the front opening () is and which connects the first lumen () to the outside, and a cutting wire (), which is located in the first lumen () in an axially displaceable manner and extends through the front opening () and the rear opening () and is located on the outside between the front opening () and the rear opening (). When the cutting wire () is tensioned, the free end region is deformed in a arc shape and the cutting wire () forms a transversely extending cutting edge () between the front opening () and the rear opening (). The front opening () is arranged at a distance of at least 3 mm from the free end (). A projection () is formed between the free end () and the front opening (). A cutting tip () is formed at the free end () of the catheter (). The cutting tip is connected to the cutting wire () and forms the foremost end of the papillotome.
