(JA) 医療デバイス
Abstract:
(EN) Provided is a medical device that is capable of not only preventing contact between a guide wire and a rotating body during a procedure but also cutting an object with the rotating body with an improved cutting efficiency. A medical device (1) has: a sheath (10) insertable into a living body lumen; a rotatable hollow rotating body (110) disposed in such a manner as to protrude from a tip of the sheath; and a guide wire lumen (181a, 182a) through which a guide wire (w) can be inserted in parallel with the sheath, wherein an edge (113a) of the rotating body has a corrugated portion (113, 119).
(FR) L'invention concerne un dispositif médical permettant non seulement d'empêcher un contact entre un fil de guidage et un corps rotatif pendant une intervention, mais également de couper un objet avec le corps rotatif avec une efficacité de coupe améliorée. Un dispositif médical (1) comprend : une gaine (10) pouvant être insérée dans une lumière de corps vivant ; un corps rotatif creux (110) pouvant effectuer des rotations disposé de manière à faire saillie à partir d'une pointe de la gaine ; et une lumière de fil de guidage (181a, 182a) à travers lequel un fil de guidage (w) peut être inséré en parallèle avec la gaine, un bord (113a) du corps rotatif ayant une partie ondulée (113, 119).
(JA) 処置を行っている最中にガイドワイヤと回転体とが接触するのを防止でき、かつ、回転体による物体の切削効率の向上が図られた医療デバイスを提供する。 医療デバイス(1)は、生体管腔に挿入可能なシース(10)と、シースの先端側へ突出するように配置された回転可能な中空形状の回転体(110)と、シースと並行してガイドワイヤ(w)が挿通可能なガイドワイヤルーメン(181a、182a)と、を有し、回転体の先端面(113a)は、凹凸部(113、119)を有する。
