External Pulse Generator Device and Associated Methods for Trial Nerve Stimulation

摘要

Systems and methods for providing a trial neurostimulation to a patient for assessing suitability of a permanently implanted neurostimulation are provided herein. In one aspect, a trial neurostimulation system includes an EPG patch adhered to a skin surface of a patient and connected to a lead extending through a percutaneous incision to a target tissue location. The EPG may be a modified version of the IPG used in the permanent system, the EPG may be smaller and/or lighter than the corresponding IPG device. The EPG and a lead extension may be sealed to allow improved patient mobility and reduced risk of infection. The EPG may be compatible with wireless systems used to control and monitor the IPG such that operation and control of the EPG is substantially the same in each system to allow seemless conversion to the permanently implanted system.

主权项

1. A neurostimulation system comprising:
an implantable neurostimulation lead having one or more conductors disposed within a lead body, the one or more conductors extending from a proximal end of the lead to one or more neurostimulation electrodes disposed at or near a distal end of the lead; an external pulse generator electrically coupleable to the implantable lead, the pulse generator being electrically coupled with the one or more neurostimulation electrodes when electrically coupled with the implantable lead, wherein the pulse generator is configured to generate a plurality of electrical impulses for delivering a neurostimulation treatment to a patient through the one or more neurostimulation electrodes when implanted at a target location; and an adherent patch adapted to substantially cover the external pulse generator and adhere to a skin of the patient so as to support the external pulse generator on the skin of the patient for a duration of a trial period to assess efficacy of the neurostimulation treatment.
