Methods for peripheral nerve stimulation
First Claim
1. A transcutaneous method of stimulating at least one nerve in an arm or wrist of a patient, the method comprising:
- placing a circumferential band comprising a first electrode and a second electrode around the patient'"'"'s arm or wrist, the electrodes configured to be in a configuration 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 extending between a first nerve and the first electrode and a line extending between the first nerve and the second electrode, the first nerve selected from the patient'"'"'s median, radial and ulnar nerves, wherein the first and second electrodes are spaced a predetermined distance apart, wherein the band consists of two or three stimulation electrodes and one or more additional components operably connected to the band that are not stimulation electrodes; and
delivering a first electrical stimulus between the first and second electrodes to preferentially stimulate the first nerve, the first electrical stimulus generated from a pulse generator.

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.

16. A transcutaneous method of stimulating at least one nerve in an arm or wrist of a patient, the method comprising:
-
placing a band comprising a first electrode and a second electrode around the patient'"'"'s arm or wrist in a configuration 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 extending between a first nerve in the patient'"'"'s arm or wrist and the first electrode and a line extending between the first nerve and the second electrode, wherein the first and second electrodes are configured to be spaced a predetermined distance apart, wherein the band consists of two or three stimulation electrodes and one or more additional components other than stimulation electrodes which are operably connected to the band delivering a first electrical stimulus from the first and second electrodes to excite the first nerve, the first electrical stimulus generated from the pulse generator which is operably connected to the electrodes and the band. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A transcutaneous method of stimulating at least one nerve in the arm or wrist of a patient, the method comprising:
-
determining a circumference of a patient'"'"'s wrist; providing a band and housing having a predetermined circumferential spacing for a first electrode, a second electrode, and a third electrode, wherein the predetermined circumferential spacing is based on the determined circumference of the patient'"'"'s wrist, wherein the housing encloses a pulse generator configured to be in electrical communication with the first electrode, the second electrode, and the third electrode, wherein the band and housing are configured to be positioned on the wrist such that the first electrode is positioned along the midline of the dorsal side of the arm or wrist, the second electrode is positioned approximately along the midline of the ventral side of the arm or wrist, and the third electrode is positioned in between the first electrode and second electrode, wherein the first electrode and the second electrode form a first electrode pair and the first electrode and third electrode form a second electrode pair, wherein the band consists of two or three stimulation electrodes and one or more additional components operably connected to the band that are not stimulation electrodes; stimulating a first nerve by delivering a first electrical stimulus between the first electrode pair; and stimulating a second nerve by delivering a second electrical stimulus between the second electrode pair. - View Dependent Claims (26, 27, 28, 29)
