Abstract
Cette invention concerne un dispositif médical (10) du type gaine dilatatrice radioélectrique conçue pour séparer une structure oblongue (11) prise dans des tissus, telle qu'un conducteur électrique cardiaque implanté dans un tissu biologique (12) du type vaisseau relié au coeur d'un patient. La gaine dilatatrice radioélectrique est constituée de gaines dilatatrices coaxiales, interne et externe (13 et 28), dotées d'extrémités distales biseautées respectives (18 et 36) conçues pour décoller mécaniquement et séparer un conducteur électrique cardiaque implanté des tissus dans lesquels il est pris. L'extrémité distale biseautée de la gaine interne est coupée de manière à former une face ou surface transversale (89) qui est sensiblement perpendiculaire à l'axe longitudinal de la gaine. Des conducteurs électriques (16 et 17) sont positionnés autour de l'extrémité distale (14) et du passage (15) de la gaine dilatatrice interne. Lorsqu'il est mis sous tension, le conducteur électrique émet un arc électrique qui sépare électriquement les tissus enveloppants de la structure électrique oblongue qui y est implantée et qui est placée dans le passage de la gaine dilatatrice oblongue interne.
