Electrode configurations for electrical stimulation systems and methods of making and using
View Patent ↗A paddle lead can include a plurality of first electrodes disposed entirely on a first major surface of the lead body and a plurality of second electrodes disposed entirely on a second major surface of the lead body. A paddle lead may include a plurality of electrodes in at least one column on a paddle body and a strip electrode disposed on the paddle body. A lead may include a lead body with an ellipse-like cross-section and a plurality of electrodes disposed circumferentially around the lead body and proximate to a distal end of the lead body.
1. A paddle lead, comprising:
a paddle body comprising a first major surface, a second major surface opposite the first major surface, and a first side surface connecting the first major surface to the second major surface;
a plurality of first electrodes disposed on the first major surface in at least one column, wherein at least four of the first electrodes are disposed in a first column; and
a first strip electrode disposed on the first side surface of the paddle body, wherein the first strip electrode opposes at least a center portion of the at least four first electrodes of the first column and is the only electrode disposed on the first side surface.
2. The paddle lead of claim 1 , wherein the first strip electrode is straight.
3. The paddle lead of claim 2 , wherein the paddle body further comprises a second side surface and the lead further comprises a second strip electrode disposed entirely on the second side surface.
4. The paddle lead of claim 3 , wherein the first strip electrode is disposed on a portion of the first side surface that is opposite the portion of the second side surface on which the second strip electrode is disposed.
5. The paddle lead of claim 3 , wherein the second side surface is opposite the first side surface.
6. The paddle lead of claim 2 , further comprising a plurality of second electrodes disposed on a surface different from the first major surface.
7. The paddle lead of claim 6 , wherein the plurality of second electrodes is disposed entirely on the second major surface.
8. The paddle lead of claim 7 , wherein the first electrodes are disposed in at least two columns on the first major surface, each column containing a plurality of the first electrodes.
9. The paddle lead of claim 8 , wherein the second electrodes are disposed in at least two columns on the second major surface, each column containing a plurality of the second electrodes.
10. The paddle lead of claim 1 , further comprising a plurality of second electrodes disposed on the first major surface and disposed in a second column parallel to the first column.
11. The paddle lead of claim 1 , wherein the first strip electrode opposes an entirety of at least four of the plurality of first electrodes which are arranged in a column parallel to the first strip electrode.
12. A stimulation system, comprising:
the paddle lead of claim 1 ; and
a control module coupleable to the paddle lead.
