First Claim
Patent Images
1. A nerve overwrap for an implantable nerve stimulation system, the nerve overwrap comprising:
- multiple helixes including two or more electrically active helixes and an electrically inactive helix, each of the multiple helixes being configured to substantially surround a nerve of a patient in a helical configuration having more than one turn; and
a sheet of electrically insulative material having an electrical resistivity of from about 108 ohm*m to about 1020 ohm*m, wherein the sheet has dimensions configured to wrap substantially around the multiple helixes and around the nerve of the patient.

23. A method for implanting a nerve stimulation system, the method comprising:
-
wrapping a sheet of insulative material around a nerve of a patient, wherein the insulative material has an electrical resistivity of from about 108 ohm*m to about 1020 ohm*m, wherein the sheet wraps substantially around multiple helixes including two or more electrically active helixes and an electrically inactive helix and wherein, when the sheet is wrapped around the nerve, each of the multiple helixes substantially surrounds the nerve of the patient in a helical configuration having more than one turn; and attaching opposing ends of the sheet together.
