Patent ID: 7769472

Claim:
An implantable electrical stimulation lead comprising: a lead body extending between a proximal end and a distal end; a plurality of electrical conductors within the lead body; and a plurality of stimulation electrodes, each of the electrodes being coupled to at least one of the conductors, wherein a cross-section of the distal end taken in a direction substantially perpendicular to a longitudinal axis of the lead body defines a substantially continuous concave surface and a substantially convex surface, the convex surface being on an opposite side of the cross-section as the substantially concave surface, the electrodes are positioned at various positions on the concave surface and the convex surface, the electrodes comprise conductive pads, the substantially continuous concave surface defines a channel-like region at the distal end, the substantially concave surface comprises a first portion comprising at least one of the electrodes and a second portion that faces toward the first portion and comprises at least one of the electrodes, wherein at least one of the electrodes is positioned on the concave surface but not the convex surface, and wherein an outer width of the cross-section of the distal end is greater than an outer diameter of the lead body.
