1. An esophageal device for diagnosing Upper Esophageal Sphincter (UES) pathology, the esophageal device comprising:
- (a) a intra-luminal pressure sensor configured to measure UES pressure when the intra-luminal pressure sensor is located within an Upper Esophageal Sphincter of a patient;
(b) a fluid infusion device including;
tubing configured for insertion into an esophagus of a patient;
a pump configured to inject fluid into the tubing, wherein, when the tubing is inserted into the esophagus, injection of the fluid invokes a pharyngeal reflux in the patient; and
a controller configured to control a pump pressure of the pump;
(c) an output device;
(d) an article of manufacture communicatively coupled with the output device, the article of manufacture including a processor and a non-transitory computer readable medium having computer readable program code disposed therein, the computer readable program code comprising a series of computer readable program steps to effect;
receiving indicia about the UES pressure measured by the intra-luminal pressure sensor when the pharyngeal reflux occurs in the patient;
comparing the received said UES pressure of the patient with a predetermined said UES pressure, wherein the predetermined said UES pressure is determined from at least one said UES pressure of a corresponding control subject when the corresponding control subject experiences pharyngeal reflux; and
transmitting a result of the comparison to the output device accessible by a health care provider diagnosing the patient; and
(e) a non-invasive device that compresses a cricoid of the patient thereby changing the UES pressure detected by the intra-luminal pressure sensor, wherein the non-invasive device comprises;
a cushion, a band coupled to the cushion, and a coupling clasp attached to the band, wherein when the band is placed in tension in a preset configuration about a neck of the patient using the clasp, the cushion is compressed towards the cricoid and the UES pressure within the Upper Esophageal Sphincter is set at a predetermined intra-luminal pressure suitable for treating a patient having an abnormality in UES anatomy, physiology, or functionality,wherein when the band is placed in the preset configuration using the clasp a relative position of a first end of the band to a second end of the band provides an identifier that the non-invasive device will induce the predetermined intra-luminal pressure.

Abstract
An esophageal device is used to recognize, diagnose, characterize, or relieve an impact of an abnormal or defective UES anatomy, physiology, or functionality. In one implementation, the esophageal device measures a UES response to esophageal fluid infusion to detect or characterize an abnormality or defective UES anatomy, physiology, or functionality. An Upper Esophageal Sphincter compression device is used to increase intra-luminal pressure within the Upper Esophageal Sphincter of a patient in order relieve an impact of an abnormal or defective UES anatomy, physiology, or functionality.

6. A method for determining esophageal pressure, the method comprising:
-
(a) inserting a catheter into an esophagus of a patient, wherein the catheter; includes an intra-luminal pressure sensor; and is coupled to a pump configured to inject fluid into the catheter; (b) providing data to a controller that varies a pump pressure of the pump, whereby fluid is injected into the catheter to invoke a pharyngeal reflux in the patient; (c) associating the pharyngeal reflux with an intra-luminal pressure detected by the intra-luminal pressure sensor when the pharyngeal reflux occurs in the patient; (d) comparing the intra-luminal pressure when the pharyngeal reflux occurs in the patient with a predetermined said intra-luminal pressure determined from at least one said intra-luminal pressure detected when one said pharyngeal reflux occurs in a corresponding control subject; (e) diagnosing a functionality of a Upper Esophageal Sphincter (UES) of the patient based on a result of the comparison; (f) using a Upper Esophageal Sphincter (UES) compression device to apply an external pressure to a cricoid of the patient until the intra-luminal pressure sensor denotes that the intra-luminal pressure is within a predetermined range; (g) associating the intra-luminal pressure that is within the predetermined range with a value of an indicator of the UES compression device; (h) removing the intra-luminal pressure sensor; (i) releasing the external pressure; and (j) prescribing that the value be reapplied to the indicator of the UES compression device, wherein the value is set at a predetermined amount suitable for treating a patient having an abnormality in UES anatomy, physiology, or functionality. - View Dependent Claims (7)
