Abstract
An apparatus for monitoring a nerve includes a Foley type catheter having an exterior surface, and first and second pairs of ring electrodes formed on the exterior surface of the Foley catheter. Each of the first and second pairs of ring electrodes is configured to perform at least one of stimulating the nerve and recording nerve activity.
Claims21
An apparatus for monitoring a nerve, comprising:
- a Foley type catheter having an exterior surface;
- first and second pairs of ring electrodes formed on the exterior surface of the Foley catheter, wherein the second pair of ring electrodes delivers bipolar nerve stimulation, and the first pair of ring electrodes provides bipolar recording of nerve activity;
- a processing apparatus to process the recorded nerve activity;
- and
- a first conductor coupled to the processing apparatus and the first pair of ring electrodes to carry signals representing the recorded nerve activity to the processing apparatus.
2 more elements
A method of monitoring nerve activity, comprising:
- deploying a Foley type catheter in a urethra of a human patient, wherein the Foley type catheter comprises a first pair of ring electrodes and a second pair of ring electrodes;
- stimulating a nerve;
- recording nerve activity resulting from the stimulation with at least one of the first and second pairs of ring electrodes;
- and
- calculating a nerve conduction velocity based on the recorded nerve activity.
2 more elements
A system for monitoring a nerve from a urethra of a patient, the system comprising:
- a Foley type catheter configured to be deployed in the urethra and comprising a first pair of ring electrodes and a second pair of ring electrodes, wherein each of the first and second pairs of ring electrodes records nerve activity;
- and
- a monitor apparatus in communication with the first and second pairs of ring electrodes to process the recorded nerve activity.
