Patent Images
1. A lead assembly comprising:
- a lead body extending from a proximal end portion to a distal end portion, the lead body having at least one inner lumen and one or more exit lumens;
at least one cable disposed within at least a portion of the lead body, the at least one cable having at least two coiled electrode portions and non-electrode portions;
the non-electrode portions of the cable extending along within the inner lumen of the lead body, the at least two coiled electrode portions exiting through at least one of the exit lumen and coiled around an exterior portion of the lead body and forming electrodes; and
at least one non-electrode portion disposed between a first coiled electrode portion and a second coiled electrode portion, the first coiled electrode portion coiled in an opposite direction as the second coiled electrode portion.

6. A lead assembly comprising:
-
a lead body extending from a proximal end portion to a distal end portion, the lead body having at least one inner lumen and one or more exit lumens; at least two cables disposed parallel to one another within at least a portion of the lead body, the at least two cables each having at least one electrode portion and at least one non-electrode portion; and the non-electrode portions of the cable extending along within the at least one inner lumen of the lead body, the at least two cables exiting through at least one of the exit lumens and are coiled around an exterior portion of the lead body and forming a first coiled electrode portion and a second coiled electrode portion, and a current wave of the first coiled electrode portion is toward the distal end portion and a current wave of the second coiled electrode portion is toward the proximal end portion. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
