Adaptive airway treatment of dorsal displacement disorders in horses
View Patent ↗An adaptive airway treatment system is described for treating a dorsal displacement disorder in a horse. A pacemaker processor generates a dorsal displacement disorder treatment signal as a function of at least one therapy parameter. One or more stimulation electrodes are adapted to interface with tissue of the horse for delivering the treatment signal to continuously or intermittently stimulate soft palate tissue of the horse during an entire period of increased activity of the horse or for training prior to exercise.
1. A method of using an airway treatment system for treating a dorsal displacement disorder in a horse, the method comprising:
sensing displacement of a laryngeal anatomical structure relative to an airway of the horse using one or more sensing electrodes;
generating a dorsal displacement disorder treatment signal based on the displacement, using a pacemaker processor, to strengthen one or more muscles involved in displacing the laryngeal anatomical structure relative to the airway of the horse; and
using one or more stimulation electrodes, configured to interface with tissue of the horse, to deliver the treatment signal to the tissue of the horse to maintain an unobstructed airway.
2. The method of claim 1 , wherein the laryngeal anatomical structure includes the larynx of the horse and/or the epiglottis of the horse.
3. The method of claim 1 , wherein the tissue of the horse includes one or more of geniohyoid muscle tissue, mylohyoid muscle tissue, nerve tissue to the palatoglossus muscle, nerve tissue to the palatopharyngeous muscle, thyrohyoid muscle tissue, and nerve tissue to the thyrohyoid muscle.
4. The method of claim 1 , wherein sensing the displacement of a laryngeal anatomical structure relative to the airway includes a reduced distance between larynx and basihyoid bone.
5. The method of claim 1 , wherein sensing the displacement of a laryngeal anatomical structure relative to the airway includes a reduced distance between larynx and chin.
6. The method of claim 1 , wherein sensing the displacement of a laryngeal anatomical structure relative to the airway includes a reduced distance between larynx and basihyoid bone and chin simultaneously.
7. The method of claim 1 , wherein sensing the displacement of a laryngeal anatomical structure relative to the airway includes a reduced distance between basihyoid and larynx and ventral aspect of the petrous temporal/basisphenoid bone.
8. The method of claim 1 , further comprising recording the displacement using the pacemaker processor.
9. The method of claim 1 , further comprising:
monitoring the displacement using the pacemaker processor; and
adjusting the treatment signal based on the monitored displacement.
10. The method of claim 1 , further comprising:
monitoring the treatment signals using the pacemaker processor; and
adjusting the treatment signal based on the monitored treatment signals.
11. The method of claim 1 , wherein the one or more sensing electrodes includes an electromyogram, an electronystagmograph, an electroglottograph, an electroencephalograph, a biopotential sensor, an ultrasound sensor, a hall sensor, a microphone, a pressure sensor, a strain transducer, a mechanical deformation sensor, a motion sensor, or combinations thereof.
12. The method of claim 1 , wherein the treatment signal is applied to the tissue based on a biphasic waveform.
13. The method of claim 1 , wherein the one or more stimulation electrodes include a cuff electrode, a multipolar cuff electrode, a tripolar cuff electrode, a flat nerve electrode, an epineural electrode, a shaft electrode, a longitudinal intrafascicular electrode, a thin wire electrode, a micro-machined electrode, a sieve electrode, or combinations thereof.
14. The method of claim 1 , wherein the one or more stimulation electrodes are configured to cause stimulation to a specific area of the tissue of the horse by differential activation.
15. The method of claim 1 , wherein the treatment signal is delivered continuously over a period of hours until the system is turned off.
16. The method of claim 1 , wherein the treatment signal is further based on air flow characteristics of the airway tract of the horse, contractile characteristics of the airway tissue of the horse, electrical characteristics of a portion of the body of the horse, temperature of a portion of the body of the horse, pH of a portion of the body of the horse, chemical constituency of a portion of the body of the horse, physiological state of the horse or combinations thereof.
17. The method of claim 1 , further comprising monitoring operation of the pacemaker processor using a treatment verification monitor.
