摘要： A cochlear stimulation lead and method of making an aggressively curved electrode array are provided. In one embodiment of the lead, while the curved section of the lead is curled further beyond the originally molded curvature and held in this position, a filling channel is filled up with a filling material that is hardened or cured in this held position. The resulting lead has a tip curvature that is more curved than the originally molded curvature.

摘要： A multicontact electrode array suitable for implantation in living tissue includes a distal end having multiple spaced-apart ring contacts or a pattern of spaced-apart electrode contacts carried on a flexible carrier. Each electrode contact is resistance welded to a respective wire that is wound helically inside a silicon tube. The center of the helix defines a lumen wherein a positioning stylet, or other suitable positioning tool, may be removably inserted when the electrode array is implanted. The electrode array is made using a method that includes, as an initial step, winding lead wires around a suitable mandrel forming a helix configuration. Next, a non-conductive silicone tube jacket is placed around the wound wires, exposing the distal lead ends of the wires at a distal end of the tube. A welding process is then used to bond each wire tip to a corresponding metal electrode contact which has been preassembled by resistance welding to a metal foil structural carrier. The electrode array, including the metal foil structural carrier, is then formed into a tube by drawing it through a die. The excess foil material at the distal tip is then trimmed and a heat-shrink tube is placed around the assembled foil tube to prevent leakage of the polymer filler material through the joining longitudinal line of the carrier. Next, the foil tube is injected with a polymer filler material to void any gaps between the lead wires and contacts. To avoid filling the central lumen with the polymer filler material, a central core or stylet is temporarily placed inside the lumen. The heat-shrink tube is then mechanically removed. The fabrication method is finalized by inserting the preassembled electrode array into a hot acid mixture, which etches away the metal foil carrier, exposing the contacts at the surface of a distal end of the electrode array.

摘要： An insertion kit for implanting an electrode in a patient can include a handle; an insertion member coupled to the handle at a proximal end of the insertion member and configured and arranged to be inserted into a patient; an alignment member coupled to the handle and disposed over the distal end of the insertion member; and an electrode configured and arranged to be inserted into the patient using the insertion member. In some instances, the insertion kit may also include one or more of a marker that cooperates with the alignment member to mark a position of the electrode on the skin of the patient; a pointer that cooperates with the alignment member to find the marked position on the skin of the patient; and a second electrode and a second insertion member configured and arranged for detachably coupling to the handle in place of the insertion member.
