Beschreibung
Zusammenfassung:	Provided is a biodegradable or bioabsorbable tubular body in which the opening of a slit during water absorption is suppressed. A tubular body including a plurality of layers formed of a biodegradable or bioabsorbable material is provided with a slit along the longitudinal direction over the entire length of the longitudinal direction, and a tension in the circumferential direction in the inner layer is larger than that in the outer layer of the plurality of layers. L'invention concerne un corps tubulaire biodégradable ou bioabsorbable dans lequel l'ouverture d'une fente pendant l'absorption d'eau est supprimée. L'invention concerne un corps tubulaire comprenant une pluralité de couches formées d'un matériau biodégradable ou bioabsorbable avec une fente le long de la direction longitudinale sur toute la longueur de la direction longitudinale, et une tension dans la direction circonférentielle dans la couche interne est plus grande que celle dans la couche externe de la pluralité de couches. 吸水時におけるスリットの開きを抑制する生分解性又は生体吸収性の筒状体を提供する。生分解性又は生体吸収性の材料で形成された複数の層を含む筒状体であって、長手方向に沿って、該長手方向の全長にわたるスリットが設けられ、前記複数の層のうち外側の層に比して内側の層における周方向の張力が大きい。
