(JA) 医療デバイス
Abstract
(EN)
Provided is a medical device having an expansive body formed of wire rods wherein twisting of the wire rods in the circumferential direction can be inhibited. This medical device (10) is for expanding a living tissue and is provided with: an elongated shaft part (20); and an expansive body (21) provided at the leading end of the shaft part (20). The expansive body (21) has: wire rod parts (50) capable of radially expanding and contracting; and torsion restriction parts (54) for restricting the movement of the wire rod parts (50) in the circumferential direction of the expansive body (21).
(FR)
L'invention concerne un dispositif médical ayant un corps expansif formé de tiges de fil, la torsion des tiges de fil dans la direction circonférentielle pouvant être inhibée. Ce dispositif médical (10) est destiné à dilater un tissu vivant et comporte : une partie tige (20) allongée; et un corps expansif (21) disposé au niveau de l'extrémité avant de la partie tige (20). Le corps expansif (21) comprend : des parties de tige de fil (50) capables de se dilater et de se contracter radialement; et des parties de restriction de torsion (54) pour restreindre le mouvement des parties de tige de fil (50) dans la direction circonférentielle du corps expansif (21).
