INTRACORPOREAL INDWELLING EQUIPMENT
First Claim
1. Apparatus for intracorporeal indwelling, in which the intracorporeal indwelling equipment has a cylindrical member to be set in the fistula formed between the skin side wall portion on the body of the patient and the wall portion of the prescribed portion in the body of the patient, and an internal holding member that is connected to the tip of said cylindrical member and is set on the inner side of said prescribed portion, and it is for the fluid flow between the exterior of said patient and the interior of said prescribed portion;
- said internal holding member being composed of multiple flexible ribbon-shaped members, each bending from the opening edge at the tip of said cylindrical member towards the outer side and bonded to each other at their tips, and flexible membrane-like members set on the portions of said multiple ribbon-shaped members on said cylindrical member side and forming a dome-like portion together with said multiple ribbon-shaped members; and
wherein a notch is formed on the outer periphery of the membrane-like members of said dome-like portion;
when said multiple ribbon-shaped members are stretched so that the tip bonding portions of said ribbon-shaped members separate from said cylindrical member, said membrane-like members are folded, with said notch taken as the base of the crease.

Abstract
The present invention provides an intracorporeal indwelling equipment having an internal holding member to be set in the stomach. Said internal holding member is composed of flexible ribbon-shaped members and flexible membrane-like members that are set on the portions of ribbon-shaped member, forming a dome-shaped portion. In the center of the outer periphery of membrane-like member, a notch and folding creases are formed to assist in deployment and help prevent the generation of ulcers and buried bumper syndrome.

- 8. Intracorporeal indwelling equipment comprising a tube member for insertion into a patient and an interior fixing member attached to a distal end of the tube member at a connection region, the interior fixing member comprising a plurality of resilient support members connecting a coupling member to said connection region characterized in that said interior fixing member further comprises a plurality of foldable membrane-like members attached to and between said support members.
- 21. An intracorporeal indwelling equipment comprising an extension tube and an internal holding member attached to a peripheral end of said extension tube by a connection region, wherein said internal holding member comprises a coupling member and a plurality of support members connecting said coupling member to said connection region and a plurality of skirt members extending between said support members and wherein each said skirt member includes a notch region at a peripheral edge thereof and wherein a fold region extends from an apex of said notch region towards said connection region.
