PROBLEM TO BE SOLVED: To provide a biological flow channel formation induction material capable of improving flow of tissue liquid such as lymph by inducting artificially formation of a tissue gap lumen serving as a channel penetrating the tissue when being inserted into the inside of a living body.SOLUTION: Provided is a string-like material having a surface having a tissue non-adhesive property, and the string-like material is the biological flow channel formation induction material for forming the channel inside the living body along a longitudinal direction between the surface and the surrounding tissues when being inserted into the inside of the living body. For example, it is used as the formation induction material of an artificial lymph tube, an artificial urine tube, an artificial oviduct, an artificial salivary tube, an artificial sperm tube, an artificial lacrimal tube, an artificial spinal cord liquid tube, or an artificial drainage tube.COPYRIGHT: (C)2015,JPO&INPIT【課題】生体内に挿入した場合に、組織内を貫通する流路として機能する組織間隙腔の形成を人工的に誘発して、リンパ液等の組織液の流れを改善させることが可能な生体内流路形成誘導材を提供する。【解決手段】組織非接着性を持った表面を有する紐状物であり、生体内に挿入した場合に、表面と周囲組織との間に、その長手方向に沿って生体内流路が形成される生体内流路形成誘導材であり、例えば、人工リンパ管、人工尿管、人工卵管、人工唾液管、人工精管、人工涙管、人工脊髄液管、又は人工排液管の形成誘導材として使用される。【選択図】図1
