External pulse generator device and associated methods for trial nerve stimulation
First Claim
1. A neurostimulation system comprising:
- an implantable neurostimulation lead having one or more conductors extending from a proximal end of the implantable neurostimulation lead to one or more neurostimulation electrodes disposed at or near a distal end of the implantable neurostimulation lead;
an external pulse generator electrically coupleable to the implantable neurostimulation lead, the external pulse generator being electrically coupled with the one or more neurostimulation electrodes when electrically coupled with the implantable neurostimulation lead, wherein the external pulse generator is configured to generate a plurality of electrical impulses for delivering a trial neurostimulation treatment to a patient through the one or more neurostimulation electrodes when implanted at a target location;
wherein the external pulse generator includes a single button, the button being configured to turn on the external pulse generator for delivery of the trial neurostimulation treatment, and wherein a housing of the external pulse generator lacks manual stimulation adjustment controls disposed thereon; and
an implantable pulse generator adapted to deliver a neurostimulation therapy through the one or more neurostimulation electrodes of the implantable neurostimulation lead based on the trial neurostimulation treatment, wherein the external pulse generator and the implantable pulse generator are configured to wirelessly couple with a patient remote, the patient remote being configured to control stimulation or monitor a battery status of the external pulse generator and the implantable pulse generator in a substantially same manner.

Abstract
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 seamless conversion to the permanently implanted system.

10. A method of delivering a neurostimulation treatment, the method comprising:
-
implanting a distal end of a neurostimulation lead in a target location in a patient, the distal end of the neurostimulation lead having one or more neurostimulation electrodes; electrically coupling the neurostimulation lead to an external pulse generator, wherein the external pulse generator includes a single button, the button being configured to turn on the external pulse generator, and wherein a housing of the external pulse generator lacks manual stimulation adjustment controls disposed thereon; performing one or more trial neurostimulation treatments with the neurostimulation lead and the external pulse generator during a trial period; implanting an implantable pulse generator and connecting to the neurostimulation lead implanted within the patient; performing a neurostimulation treatment therapy with the implanted neurostimulation lead and the implantable pulse generator based on the one or more trial neurostimulation treatments performed with the external pulse generator; and coupling the implantable pulse generator with a patient remote, wherein the patient remote is configured to control stimulation or monitor a battery status of the implantable pulse generator in a substantially same manner as the external pulse generator. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
