Summary:The endocardial heart stimulator tube has a positive fixture using an extendable and retractable screw thread in combination with a very flexible heart stimulator tube. It has a stress release element near the joint of the electrode and the conductor of the endocardial heart stimulator tube. The screw thread fixing element rotates to secure the electrode to the endocardial tissue. The fixing element contains a screw thread shaped coil with enclosed end and a sharp point. A flush sliding element (32) is attached to the tip of the coil (34). There is a rectangular hole at the end of a tunnel used to turn the coil. CE CONDUCTEUR POUR STIMULATION ENDOCARDIAQUE COMPREND UN ORGANE HELICOIDAL DE FIXATION 34 S'ETENDANT VERS L'EXTERIEUR A TRAVERS UNE LUMIERE HELICOIDALE MENAGEE DANS UN ORGANE 36 D'ETANCHEITE ET DE GUIDAGE DISPOSE DANS UNE EXTREMITE DISTALE D'UNE ELECTRODE 12 POUR FIXER CELUI-CI DANS LES TISSUS DU COEUR. UN MANDRIN CONSTITUE PAR UN FIL, OU STYLET, 20A AYANT UNE EXTREMITE 20B EN FORME DE COIN ENTRAINE EN ROTATION UN ELEMENT COULISSANT 32 CONVERGENT PORTANT L'EXTREMITE FERMEE 34A DE L'ORGANE HELICOIDAL 34, A L'INTERIEUR DE L'ELECTRODE 12, TANDIS QUE SON EXTREMITE OPPOSEE EFFILEE 34B SORT A TRAVERS UNE MINCE MEMBRANE D'EXTREMITE ET DE GUIDAGE. UN ENROULEMENT 30 DE SUPPRESSION DES CONTRAINTES EST PREVU A LA JONCTION DU CONDUCTEUR ET DE L'ELECTRODE.
