This invention is directed to implantable coils and, more particularly, to a coil (10) implant having a stretch-resistant (40) member internal to the coil. The implant of the invention is able to freely articulate and torque prior to delivery. Once delivered, the implant is no longer stretch resistant and is therefore able to substantially conform to the vascular site.Linvention concerne des bobines implantables et, plus particulièrement, un implant de bobine muni dun élément résistant à létirement interne de la bobine. Limplant de linvention peut sarticuler librement et se tordre avant distribution. Une fois distribué, limplant nest plus résistant à létirement et peut donc sensiblement se conformer au site vasculaire.
