Catheter system for catheter-assisted pancreato-gastrostomy after pancreatic head resection

摘要

Catheter system for pancreato-gastrostomy after a pancreatic head resection on a human or animal body having an abdomen (84) bounded by an abdominal wall (82), comprising a first catheter in the form of a tubular pancreatic duct catheter (10) with a tube wall (12) forming a first channel (14) for establishing a fluid conducting connection from a pancreatic duct (88) through the abdominal wall (82), the pancreatic duct catheter (10) being spaced from a first opening (18) at a first end (20 ) to a second opening (22) at a second end (24) has a first predetermined length, wherein in functional position of the pancreatic duct catheter (10) the first end (20) with the first opening (18) extraabdominal and the second end ( 24) with the second opening (22) is arranged intraabdominally in the pancreatic duct (88), characterized in that the catheter system additionally comprises a second catheter (16), which in a Kath eter housing (30) forms a second channel (32) extending a second predetermined length in the catheter housing (30) from a first catheter eye (34) at a first end (36) of the catheter housing (FIG. 30) of the second catheter (16) to a second catheter eye (38) at a second end (40) of the catheter housing (30) of the second catheter (16), wherein in functional position of the second catheter (16) on the human or animal body, the first end (36) of the catheter housing (30) of the second catheter (16) extraabdominal and the second end (40) of the catheter housing (30) of the second catheter (16) is intraabdominally arranged and the Catheter housing (30) extends through the abdominal wall (82), wherein the second channel (32) in the catheter housing (30) of the second catheter (16) for receiving the pancreatic duct catheter (10) is formed such that the pancreatic duct catheter (10) in the second channel (32) relative to the catheter-G housing (30) of the second catheter (16) is displaceable, wherein the second predetermined length of the second channel (32) in the second catheter (16) is shorter than the first predetermined length of the pancreatic duct catheter (10), wherein a third opening (42) at or spaced from the first end (36) of the catheter housing (30) of the second catheter (16) is formed such that this third opening (42) in the functional position of the second catheter (16) is arranged extraabdominal, wherein a fourth aperture (44) is disposed at or spaced from the second end (40) of the catheter housing (30) of the second catheter (16) such that said fourth aperture (44) is intraabdominally disposed in the operative position of the second catheter (16) wherein a third channel (46) is disposed and formed in the catheter housing (30) of the second catheter (16) such that said third channel (46) fluidly connects the third port (42) and the fourth port (44) , where the Catheter housing (30) of the second catheter (16) in the region of the fourth opening (44) comprises a magnetic material (58), wherein a further separate component (96) is provided of a magnetic material, which in functional position within a gastric lumen ( 94) of a stomach (90) in the abdomen (84) can be arranged, wherein the separate component (96) of the magnetic material and the magnetic material (58) in the region of the fourth opening (44) are formed such that between them forms a magnetic attraction, if they are below a predetermined distance from each other, such that the distance from each other automatically decreases.
