Systems for peripheral nerve stimulation
First Claim
1. An external system for stimulating at least one nerve in a patient'"'"'s arm or wrist, the system comprising:
- a pulse generator;
a circumferential band configured to be secured to the patient'"'"'s arm or wrist, the band supporting a first and a second electrode in electrical communication with the pulse generator, the first and second electrodes being spaced on the band and configured to deliver electrical stimuli from the pulse generator to the patient to preferentially excite a first nerve selected from the patient'"'"'s median, radial or ulnar nerve, the first and second electrodes being arranged and configured such that in a transverse cross-sectional plane of the arm or wrist there is a 90 degree to 180 degree angle between a line connecting the first nerve and the first electrode and a line connecting the first nerve and the second electrode; and
a controller configured to signal the pulse generator to deliver the electrical stimuli configured to preferentially stimulate the first nerve via the first and second electrodes to the patient.

Abstract
A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinsonian tremor, and other forms of tremor. The stimulator can have electrodes that are placed circumferentially around the patient'"'"'s wrist or arm. Specific nerves in the wrist or arm can be targeted by appropriate spacing of the electrodes. Positioning the electrodes on generally opposing sides of the target nerve can result in improved stimulation of the nerve. The stimulation pattern may alternate between the nerves. Improved stimulation algorithms can incorporate tremor feedback, external data, predictive adaptation, and long-term monitoring data.

12. An external system for stimulating at least one nerve in an arm or wrist of a patient, the system comprising:
-
a pulse generator; and an arm or wrist band securable to the patient'"'"'s arm or wrist, the band supporting a first and a second electrode in electrical communication with the pulse generator, the first and second electrodes being spaced on the band and configured to deliver electrical stimuli from the pulse generator to the patient to preferentially excite a first nerve selected from the patient'"'"'s median, radial or ulnar nerve, the first and second electrodes being arranged and configured such that in a transverse cross-sectional plane of the arm or wrist there is a 90 degree to 180 degree angle between a line connecting the first nerve and the first electrode and a line connecting the first nerve and the second electrode, wherein the system further comprises a controller configured to deliver an alternating stimulation pattern from the pulse generator to the first electrode and the second electrode. - View Dependent Claims (13, 14, 15, 16, 17)

18. A transcutaneous system for stimulating at least one nerve of the arm or wrist, the system comprising:
-
a circumferential band configured to be secured to the patient'"'"'s arm or wrist, the band supporting a first and a second electrode in electrical communication with a pulse generator, the first and second electrodes being spaced on the band and configured to deliver electrical stimuli from the pulse generator to the patient to preferentially excite a first nerve selected from the patient'"'"'s median, radial or ulnar nerve, the first and second electrodes being arranged and configured such that in a transverse cross-sectional plane of the arm or wrist there is a 90 degree to 180 degree angle between a line connecting the first nerve and the first electrode and a line connecting the first nerve and the second electrode, wherein the band is configured to be in electrical communication with a controller configured to deliver an alternating stimulation pattern from the pulse generator to the first electrode and the second electrode. - View Dependent Claims (19)
