System and method for improving nerve finding for peripheral nerve stimulation
First Claim
1. A method of identifying a location for applying a stimulation therapy to treat a patient, the method comprising:
- stimulating a first body region of the patient transcutaneously via a stimulus generator, wherein the first body region includes a foot that contains a first portion of a nerve that has an elongate shape;
monitoring, in response to the stimulating, action potentials received from a second portion of the nerve over a period of time, wherein the second portion of the nerve is in a second body region of the patient includes a thigh, and wherein the monitoring comprises engaging different fascicles of the second portion of the nerve as the first body region is being stimulated; and
determining, based on the monitoring, an optimized location of the second portion of the nerve for applying the stimulation therapy to treat the first body region.

Abstract
A method of identifying a location for applying a stimulation therapy to treat a patient includes stimulating a first body region of the patient transcutaneously via a stimulus generator. The body region contains a first portion of a nerve that has an elongate shape. In response to the stimulating, action potentials received from a second portion of the nerve are monitored over a period of time. The second portion of the nerve is in a second body region of the patient that is located remotely from the first body region. Based on the monitoring, an optimized location of the second portion of the nerve is determined for applying the stimulation therapy to treat the first body region.

10. A method of identifying a location for applying a stimulation therapy to treat a patient, the method comprising:
-
stimulating a first body region of the patient via an external pulse generator (EPG), the body region including a foot that contains a first portion of a nerve that has an elongate shape; sending a trigger signal to a measurement instrument, the trigger signal defining a time window for making a measurement; and measuring a plurality of different action potentials via the measurement instrument, the measuring being performed in response to a plurality of engagements with different fascicles of a second portion of the nerve while the first body region is stimulated, wherein the second portion of the nerve is in a second body region of the patient that is located in an upper leg, wherein the measuring is performed within the time window defined by the trigger signal, and wherein the stimulating, the sending, and the measuring are performed while the patient is sedated. - View Dependent Claims (11, 12, 13, 14)

15. A medical system, comprising:
-
a stimulus generator configured to apply stimulation to a foot of a patient, the foot containing a first portion of an elongate nerve; a tool configured to engage with a second portion of the nerve that is in a thigh of the patient, wherein the tool is configured to receive action potentials from the second portion of the nerve in response to the stimulation at the foot of the patient, and wherein the tool includes one of;
a seeking needle or a paddle lead; anda measurement instrument electrically coupled to the tool and configured to measure and analyze the action potentials received by the tool. - View Dependent Claims (16, 17, 18, 19, 20)
