Title
(EN) MEDICAL DEVICE INSERTED IN BODY CAVITY
(FR) DISPOSITIF MÉDICAL INSÉRÉ DANS UNE CAVITÉ CORPORELLE
(JA) 体腔内挿入医療機器
Abstract
(EN)
A medical device inserted in body cavity consisting essentially of an elastic linear material and adapted to have its distal end to reach a determined target site of biological organ, characterized in that plural curved portions lie between the hand side and distal end side of the elastic linear material, and that at least one pair of adjacent curved portions are present in different planes intersecting with each other. The medical device has self-direction controlling capability and has such a feature that through driving thereof into a body cavity, the distal end can be allowed to accurately and easily reach any determined target site of biological organ.
(FR)
La présente invention concerne un dispositif médical inséré dans une cavité corporelle consistant sensiblement en un matériau linéaire élastique et conçu pour que son extrémité distale atteigne un site cible déterminé d’un organe biologique. Le dispositif est caractérisé en ce que plusieurs parties courbées se trouvent entre le côté main et le côté d’extrémité distale du matériau linéaire élastique, et en ce qu’au moins une paire de parties courbées adjacentes se trouve dans différents plans se coupant. Le dispositif médical présente une aptitude d’auto-commande directionnelle et présente une caractéristique telle que lorsqu’on le dirige dans une cavité corporelle, l’extrémité distale peut atteindre de manière précise et aisée un quelconque site cible déterminé d’un organe biologique.
