Abstract: The invention relates to a papillotome for percutaneous endoscopic gastrostomy comprising a front opening (11), which is located in a free end region of a catheter (10) and at the outlet of a first lumen (12), a rear opening (9), which is further from a free end (17) than the front opening (11) is and which connects the first lumen (12) to the outside, and a cutting wire (16), which is located in the first lumen (12) in an axially displaceable manner and extends through the front opening (11) and the rear opening (9) and is located on the outside between the front opening (11) and the rear opening (9). When the cutting wire (16) is tensioned, the free end region is deformed in a arc shape and the cutting wire (16) forms a transversely extending cutting edge (15) between the front opening (11) and the rear opening (9). The front opening (11) is arranged at a distance of at least 3 mm from the free end (17). A projection (20) is formed between the free end (17) and the front opening (11).

Abstract: The invention relates to a PEG probe having a PEG tube, an outer holding plate, through which the PEG tube is fed and in which the PEG tube is fastened, and a funnel adapter, which is associated with an outer end region of the PEG tube. A tightly closing valve is arranged either in the PEG tube between the outer holding plate and the outer end region or on the outer end region of the PEG tube. The valve blocks the flow through the PEG tube in a closed position and allows said flow at least in the full cross-section of the PEG tube in an open position. The valve has a valve body and a valve housing. The valve body is connected to and movable by means of a handle accessible from outside. The valve body is supported in the valve housing.
