Compression device and pressure sensor for treatment of abnormal upper esophageal sphincter functionality
A 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 upper esophageal sphincter anatomy, physiology, or functionality. In one implementation, the compression device is used in conjunction with an external pressure sensing device to determine the external pressure that is to be applied to the cricoid for a specific patient. The compression device can be a means for the management and/or treatment of abnormal upper esophageal sphincter functionality, or a means for strengthening an esophageal sphincter of a subject, or a means for curing esophageal reflux disease of a subject, or a means for improving vocal function in a subject, or a means for managing lung aspiration, or a means for applying cricoid pressure during anesthesia intubation, or a means for stabilizing body structures such as during medical imaging or radiation treatment.
1. A method for strengthening an esophageal sphincter of a subject, the method comprising:
(a) providing a compression device including (i) a frame, (ii) a strap having a first end section attached to the frame and an opposite second end section attached to the frame, and (iii) a cushion disposed on the frame;
(b) positioning the compression device around a neck of the subject such that the cushion applies pressure on the neck that is transmitted to the esophageal sphincter of the subject; and
(c) repeating step (b) a plurality of times whereby the esophageal sphincter of the subject is strengthened.
2. The method of claim 1 wherein:
step (b) occurs while the subject is sleeping.
3. The method of claim 1 wherein:
a length of the strap between the first end section and the second end section is adjustable,
a clasp is attached to the second end section of the strap; and
the clasp is configured to fasten the strap to the frame to position the cushion over a cricoid of the subject and to apply the pressure on the neck that is transmitted to the esophageal sphincter of the subject.
4. The method of claim 1 wherein:
the clasp is configured to unfasten the strap from the frame and to refasten the strap to the frame to reapply the pressure on the neck that is transmitted to the esophageal sphincter of the subject.
5. The method of claim 1 wherein:
the second end section of the strap is looped through a slot of the clasp for securing the second end section of the strap to the frame.
6. The method of claim 1 wherein:
the compression device further comprises an adjustment mechanism for moving the cushion toward or away from the frame.
7. The method of claim 6 wherein:
the adjustment mechanism is configured to perform micro-pressure adjustments to the pressure on the neck.
8. The method of claim 1 wherein:
step (b) further comprises placing an electrode in contact with the neck of the subject, placing an electrical pulse generator in electrical communication with the electrode, activating the electrical pulse generator to generate a series of electrical pulses from the electrode such that the series of electrical pulses electrically stimulate the esophageal sphincter of the subject, and
the electrode is attached to the cushion.
9. The method of claim 1 wherein:
step (b) further comprises placing an electrode adjacent or in the esophageal sphincter, placing an electrical pulse generator in electrical communication with the electrode, activating the electrical pulse generator to generate a series of electrical pulses from the electrode such that the series of electrical pulses electrically stimulate the esophageal sphincter of the subject.
10. The method of claim 1 wherein:
the pressure on the neck that is transmitted to the esophageal sphincter of the subject induces an intra-luminal upper esophageal sphincter pressure to remain within a range that is 10-70 mm Hg.
11. A method for improving esophageal reflux disease of a subject, the method comprising:
(a) providing a compression device including (i) a frame, (ii) a strap having a first end section attached to the frame and an opposite second end section attached to the frame, and (iii) a cushion disposed on the frame; and
(b) positioning the compression device around a neck of the subject such that the cushion applies pressure to a cricoid of the subject; and
(c) repeating step (b) a plurality of times whereby the esophageal reflux disease of the subject is improved.
12. The method of claim 11 wherein:
step (b) occurs while the subject is sleeping.
13. The method of claim 11 wherein:
a length of the strap between the first end section and the second end section is adjustable,
a clasp is attached to the second end section of the strap; and
the clasp is configured to fasten the strap to the frame to position the cushion over a cricoid of the subject and to apply the pressure on the neck that is transmitted to the esophageal sphincter of the subject.
14. The method of claim 11 wherein:
the clasp is configured to unfasten the strap from the frame and to refasten the strap to the frame to reapply the pressure on the neck that is transmitted to the esophageal sphincter of the subject.
15. The method of claim 11 wherein:
the second end section of the strap is looped through a slot of the clasp for securing the second end section of the strap to the frame.
16. The method of claim 11 wherein:
the compression device further comprises an adjustment mechanism for moving the cushion toward or away from the frame, and
the adjustment mechanism is configured to perform micro-pressure adjustments to the pressure on the neck.
17. The method of claim 11 wherein:
the pressure applied to the cricoid of the subject induces an intra-luminal upper esophageal sphincter pressure to remain within a range that is 10-70 mm Hg.
