Patent ID: 8712546

Claim:
A neurostimulation system for use in selectively stimulating a target dorsal root ganglion having a bulbous shape, comprising: a lead having a proximal end, a distal end and an electrode, wherein the distal end of the lead is advanceable through a percutaneous access catheter, is flexible so that the lead is advanceable through the percutaneous access catheter in a substantially straightened configuration, and once advanced beyond a distal end of the percutaneous access catheter the distal end of the lead is wrappable lengthwise at least partially about the target dorsal root ganglion so as to conform to and thereby follow the bulbous shape of the target dorsal root ganglion, so that the electrode is positioned to selectively stimulate the target dorsal root ganglion; a signal generator coupled to the electrode providing energy to selectively stimulate the target dorsal root ganglion; and a controller configured to control an output of the signal generator.
