PROBLEM TO BE SOLVED: To further simply communicate two luminal organs.SOLUTION: A communication member 100 for communicating two luminal organs (for example, a lymph vessel L1 and a vein L2), the communication member is so placed as to penetrate through respective tube walls of the two luminal organs that are so arranged as to face the side parts thereof each other, and includes a tubular body part 1. In a state where outer surfaces of the body part 1 are inserted in through holes L1a and L2a of the tube walls respectively, with the outer surfaces brought into contact with the inner surfaces of the trough-holes L1a and L2a, the body part 1 is positioned in an axial direction of the body part 1 and in a radial direction intersecting with the axial direction, and is configured to be able to be placed.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】２つの管腔臓器の連通をより簡便に行う。【解決手段】２つの管腔臓器（例えば、リンパ管Ｌ１及び静脈Ｌ２）を連通させる連通部材１００であって、側部どうしを対向させるように配置された２つの管腔臓器の各管壁を貫通するように留置され、筒状の本体部１を有し、本体部１の外面を管壁の貫通孔Ｌ１ａ、Ｌ２ａの各々の内面に当接させるようにして貫通孔Ｌ１ａ、Ｌ２ａの各々に挿通された状態で、本体部１の軸方向及び軸方向と交わる径方向に当該本体部１が位置決めされて留置可能に構成されている。【選択図】図３
