Abstract: An implantable electrical stimulation lead includes a tip electrode disposed on a distal tip of the lead body. One tip electrode has a base and a separate plug attached to the base. The base defines an interior lumen closed at one end by the plug. Another tip electrode has an electrode body, a stem extending from the electrode body, and shaped retention features extending from the stem. Yet another tip electrode has an electrode body, a stem extending from the electrode body, and a flange disposed on the stem opposite the electrode body. A further tip electrode has an electrode body defining an interior lumen and a plurality of protrusions extending into the interior lumen. Another tip electrode has an electrode body and arms extending from the electrode body. The electrode body defines an interior lumen and the arms extend over an opening to the interior lumen.

Abstract: An electrical stimulation lead includes a paddle body with micro-circuit assemblies having micro-circuits laminated between electrically-nonconductive substrates. The micro-circuits have first end portions and opposing second end portions. Electrodes are electrically coupled to the first end portions of the micro-circuits. Distal end portions of one or more lead bodies are coupled to the paddle body. Terminals are disposed along proximal end portions of the one or more lead bodies. Lead-body conductors are coupled to the terminals and extend along the one or more lead bodies to distal end portions of the one or more lead bodies. The lead-body conductors are attached to the second end portions of the micro-circuits to electrically couple the terminals to the electrodes.

Abstract: First contacts are disposed along a distal end portion or a proximal end portion of a lead body of an electrical stimulation lead. A contact assembly is disposed along the other of the distal end portion or the proximal end portion of the lead body. The contact assembly includes a tubular-shaped composite structure formed from multiple layered elements mechanically coupled together and rolled together into a tube. Each of the layered elements includes a first electrically-nonconductive substrate, a second electrically-nonconductive substrate, and micro-circuits laminated therebetween. Second contacts are disposed over the composite structure and electrically coupled to a first end portion of at least one of the micro-circuits. Lead-body conductors electrically couple the first contacts to the second contacts. Each of each of the lead-body conductors is attached to a second end portion of at least one of the micro-circuits.

Abstract: A method of making a stimulation lead includes attaching multiple segmented electrodes to a carrier. Each of the segmented electrodes has a curved form extending over an arc in the range of 10 to 345 degrees. The method further includes attaching conductors to the segmented electrodes; forming the carrier into a cylinder with segmented electrodes disposed within the cylinder; molding a lead body around the segmented electrodes disposed on the carrier; and removing at least a portion of the carrier to separate the segmented electrodes.
