Abstract:
1. A kit for securing a lead within the skull of a patient, the kit comprising: a base structure adapted to be at least partially inserted within a burr hole; a lead securing member, for placement within the base structure, comprising (i) a substantially cylindrical body, (ii) an open slot in the cylindrical body, (iii) an aperture, in the cylindrical body, adjacent to the open slot, and (iv) first and second arm structures disposed on respective sides of the open slot, the first and second arm structures having proximal ends located interior to the cylindrical body and distal ends at an edge of the cylindrical body, the first and second arm structures subjected to a contracting biasing force, the first and second arm structures being pivotally mounted at respective mounting points, the aperture being disposed above the proximal ends of the first and second arm structures; and a positioning tool comprising (i) a distal end adapted to be inserted within the aperture, (ii) a pin disposed within the distal end, and (iii) a control structure for causing the pin to extend out from the distal end of the positioning tool; wherein, when the distal end of the positioning tool is disposed within the aperture of the lead securing member, (i) the first and second arm structures clamp to the distal end with sufficient force to permit the positioning tool to lift and place the lead securing member and (ii) the distal end of the positioning tool maintains the first and second arms apart to permit placement of a stimulation lead within the slot of the lead securing member; wherein, when the control structure of the positioning tool is actuated, the pin of the positioning tool is extended to force the distal end of the positioning tool from between the first and second arm structures to release the lead securing member from the positioning tool.
