Title
(EN) FLEXIBLE SOURCE WIRE FOR LOCALIZED INTERNAL IRRADIATION OF TISSUE
(FR) CABLE SOUPLE A SOURCE POUR L'IRRADIATION INTERNE LOCALISEE D'UN TISSU
Abstract
(EN)
A flexible source wire (10) is provided containing a radioactive source (160) that is capable of maneuvering through a tortuous narrow passage to a treatment site within the body. This source wire (10) includes a thin flexible housing tube (120), housing therein a flexible backbone wire (130), wherein both the tube (120) and the wire (10) are constructed from a material exhibiting little or no memory retention when bent. A radioactive core (160) is provided in the proximal end of the flexible housing tube (120) and abuts the proximal end of the backbone wire (130). Both ends of the source wire (10) are sealed and the proximal end of the source wire (10) is rounded to allow ease of movement as it travels through the bends and turns in the body.
(FR)
L'invention porte sur un câble (10) souple à source, contenant une source radioactive (160), susceptible d'être manoeuvré à travers un passage étroit et sinueux vers un endroit à traiter dans le corps. Ce câble (10) à source comporte un tube enveloppe mince et souple (120) renfermant un câble (130) à structure centrale souple, le tube (120) et le câble (10) étant constitués d'un matériau à mémorisation faible ou nulle lorsqu'il est courbé. Un c÷ur radioactif (160), placé dans l'extrémité proximale du tube enveloppe mince et souple (120), bute contre l'extrémité proximale du câble (130) à structure centrale souple. Les deux extrémités du câble (10) à source sont hermétiquement scellées et l'extrémité proximale du câble (10) à source est arrondie afin de faciliter ses mouvements lorsqu'il se déplace et tourne dans des zones courbes du corps.
