Patent ID: 8788063

Claim:
A device for brain stimulation, comprising: a lead having a longitudinal surface and a distal end, the lead comprising: a longitudinal rail disposed within the distal end of the lead and comprising a central portion and at least two prongs extending radially away from the central portion, each prong being configured and arranged to receive at least one segmented electrode: and a plurality of segmented electrodes disposed along the longitudinal surface of the lead near the distal end of the lead, each of the plurality of segmented electrodes comprising a bottom surface, a distal end, and a proximal end opposite the distal end, each of the plurality of segmented electrodes defining a passage within the segmented electrode and open at the bottom surface of the segmented electrode and extending longitudinally through the segmented electrode from the distal end to the proximal end of the segmented electrode, the passage having a shape complementary to a portion of the prongs for receiving at least the portion of a one of the at least two prongs of the rail within the passage so that the segmented electrode is disposed directly on top of the one of the at least two prongs, the portion of the one of the at least two prongs received within the passage comprising securing tabs configured and arranged to secure the segmented electrode to the prong, wherein a portion of the segmented electrode extends below each of the securing tabs.
