(FR) Capuchon recouvrant un orifice percé dans un crâne, pour fixer une électrode
요약서: front page image
(EN) A system is provided for anchoring a cranial lead 32 or catheter member within a cranial burr hole in a patient, utilizing a feed-through subassembly which permits a lead to be eccentrically positioned with respect to the centre of the burr hole, enabling fixation of the lead to the skull while the lead is maintained stereotactically rigid. The feed-through, or anchoring assembly comprises a burr hole element 30 which is positioned within the burr hole, having a radial slit 36 which extends axially through the piece and has a groove for receiving and containing an O-ring 37, which O-ring is adjustably positioned radially along the slit in accordance with the target position. The O-ring is made of a compressive material, and has a centre orifice which closely receives the lead. When the lead is inserted through the O-ring and stereotactially positioned, a clamping element is secured in place above the O-ring, compressing it so as to squeeze it inward, thereby securing the lead while it is still stereotactically fixed.
