Abstract
A stimulation lead includes a lead body having a longitudinal length, a distal portion, and a proximal portion; terminals disposed along the proximal portion of the lead body; an electrode carrier coupled to, or disposed along, the distal portion of the lead body; segmented electrodes disposed along the electrode carrier; and conductors extending along the lead body and coupling the segmented electrodes to the terminals. The electrode carrier includes a lattice region defining segmented electrode receiving openings. Each of the segmented electrodes extends around no more than 75% of a circumference of the lead and is disposed in a different one of the segmented electrode receiving openings of the electrode carrier.
Claims20
A stimulation lead, comprising:
- a lead body comprising a longitudinal length, a distal portion, and a proximal portion;
- a plurality of terminals disposed along the proximal portion of the lead body;
- a single electrode carrier coupled to, or disposed along, the distal portion of the lead body, the electrode carrier comprising a lattice region defining a plurality of segmented electrode receiving openings, wherein the lattice region is formed of a non-conductive material;
- wherein the segmented electrode recieving openings are arranged in a plurality of sets with each of the sets being disposed at a different longitudinal position along the lead;
- a plurality of electrodes comprising a plurality of segmented electrodes, each of the segmented electrodes extending around no more than 75% of a circumference of the lead, each of the segmented electrodes disposed in a different one of the segmented electrode receiving openings of the electrode carrier;
- and wherein a proximal portion of the electrode carrier is disposed proximal to all of the segmented electrodes and a portion of the lead body is disposed over the proximal portion of the electrode carrier;
- and
- a plurality of conductors extending along the lead body and coupling the plurality of electrodes to the plurality of terminals.
