## Abstract

A neurostimulation system is disclosed herein. The neurostimulation system includes an implantable pulse generator and an implantable therapy lead configured to be electrically coupled to the implantable pulse generator. The implantable therapy lead includes a flexible paddle electrode array with flexible electrodes. Each flexible electrode has a segmented configuration having first and second electrode segments and a flexible bridge or living hinge joining together the first and second electrode segments.

## Claims

### Claim 1

A neurostimulation lead comprising:
a lead body having a proximal end and a distal end
a plurality of conductive terminals being disposed at the proximal end of the lead body;
a flexible paddle being disposed at the distal end of the lead body, the flexible paddle comprising:
a row of laterally aligned flexible electrodes, the row of laterally aligned flexible electrodes at least partially contributing to the formation of a flex line in the flexible paddle; and
a row of laterally aligned nonflexible electrodes longitudinally offset from the row of laterally aligned flexible electrodes such the flex line does not extend across the row of laterally aligned nonflexible electrodes.

### Claim 2 (depends on 1)

The neurostimulation lead of claim 1, wherein at least one flexible electrode of the flexible electrodes comprises a first electrode segment and a second electrode segment spaced-apart from the first electrode segment, the flex line passing between the spaced-apart first and second electrode segments.

### Claim 3 (depends on 2)

The neurostimulation lead of claim 2, wherein the at least one flexible electrode of the flexible electrodes further comprises a flexible hinge joining the spaced-apart first and second electrode segments, the flex line passing through the flexible hinge and further wherein the flexible electrode is of unitary and continuous construction such that the first electrode segment, the second electrode segment and the flexible hinge are formed from a single material piece during manufacturing of the at least one flexible electrode; and
wherein the forming during manufacturing of the at least one flexible electrode comprises at least one of stamping or laser cutting.

### Claim 4 (depends on 3)

The neurostimulation lead of claim 3, wherein the flexible hinge comprises a V-shape or U-shape.

### Claim 5 (depends on 3)

The neurostimulation lead of claim 3, wherein the at least one flexible electrode is of an integrated construction such that at least one of the first electrode segment, the second electrode segment or the flexible hinge are separate pieces joined together during manufacturing of the flexible electrode and further wherein the joining together during manufacturing of the flexible electrode comprises at least one of welding or crimping.
