Methods, systems and devices for determining optimal placement for pudendal nerve stimulation lead using patient feedback
First Claim
1. An anal electrode device configured to measure a response of a patient to a stimulation pulse, the anal electrode device comprising:
- an elongated shaft that is configured to be at least partially inserted into an anal canal of the patient;
a first sensory electrode disposed on a first region of the shaft, wherein the first sensory electrode is configured to measure a compound motor action potential (CMAP) from an internal sphincter of the patient while the shaft is partially inserted into the anal canal of the patient; and
a second sensory electrode disposed on a second region of the shaft, wherein the second sensory electrode is configured to measure the CMAP from an external sphincter of the patient while the shaft is partially inserted into the anal canal of the patient.

Abstract
An anal electrode device is configured to measure a response of a patient to a stimulation pulse. The anal electrode device includes an elongated shaft that is configured to be at least partially inserted into an anal canal of the patient. A first sensory electrode is disposed on a first region of the shaft. The first sensory electrode is configured to measure a compound motor action potential (CMAP) from an internal sphincter of the patient while the shaft is partially inserted into the anal canal of the patient. A second sensory electrode is disposed on a second region of the shaft. The second sensory electrode is configured to measure the CMAP from an external sphincter of the patient while the shaft is partially inserted into the anal canal of the patient.

8. A medical system, comprising:
-
a pulse generator configured to generate electrical pulses as a part of an electrical stimulation therapy for a patient; a programming device configured to send programming instructions to the pulse generator to generate the electrical pulses; an anal electrode device configured to measure a compound motor action potential (CMAP) of the patient in response to the electrical pulses generated by the pulse generator, wherein the anal electrode device includes; an elongated shaft that is configured to be at least partially inserted into an anal canal of the patient; a first sensory electrode disposed on a first region of the shaft, wherein the first sensory electrode is configured to measure a compound motor action potential (CMAP) from an internal sphincter of the patient while the shaft is partially inserted into the anal canal of the patient; and a second sensory electrode disposed on a second region of the shaft, wherein the second sensory electrode is configured to measure the CMAP from an external sphincter of the patient while the shaft is partially inserted into the anal canal of the patient. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method, comprising:
-
inserting an anal electrode device into an anal canal of a patient, wherein the anal electrode device includes one or more sensory electrodes that are configured to come into contact with a sphincter of the patient after the anal electrode device has been inserted into the anal canal; programming a pulse generator to generate electrical pulses to stimulate a sacral nerve or a pudendal nerve of the patient; and measuring, at least in part via the one or more sensory electrodes, a compound motor action potential (CMAP) from the sphincter of the patient in response to the electrical pulses generated by the pulse generator. - View Dependent Claims (16, 17, 18, 19, 20)
