Systems and methods for endoscopic manometry
Systems and methods include techniques associated with endoscopic manometry. An inflatable structure may be inserted within a tissue structure and inflated or deflated to induce a physiological response for a patient. In operation, the physiological response may be induced while a patient is sedated, which may decrease physical and/or psychological pain to the patient.
1 . A method, comprising:
positioning an inflatable structure at a designated position associated with a tissue structure of a patient;
causing a change in at least one of a volume, a cross-sectional area, or a diameter of the inflatable structure;
determining the change successfully induced a target physiological response;
logging one or more measurements associated with a condition of the tissue structure;
reversing the change in at least one of the volume, the cross-sectional area, or the diameter of the inflatable structure;
causing a second change in at least one of the volume, the cross-sectional area, or the diameter of the inflatable structure;
determining the second change was unsuccessful in inducing the target physiological response;
waiting for a threshold period of time;
after the threshold period of time, determining the second change successfully induced the target physiological response;
logging one or more second measurements associated with the condition of the tissue structure; and
removing the inflatable structure from the tissue structure.
2 . The method of claim 1 , wherein the tissue structure is an esophagus and the one or more measurements are pressure measurements from a manometer.
3 . The method of claim 1 , wherein the inflatable structure is a balloon.
4 . The method of claim 1 , wherein causing the change in at least one of a volume, a cross-sectional area, or a diameter of the inflatable structure further comprises:
directing air into the inflatable structure or removing air from the inflatable structure.
5 . The method of claim 1 , wherein the target physiological response is at least one of relaxation of a lower esophageal sphincter or peristalsis.
6 . The method of claim 1 , wherein at least the positioning of the inflatable structure and the causing the change in at least one of the volume, the cross-sectional area, or the diameter of the inflatable structure is performed while the patient is sedated.
7 . A method, comprising:
positioning an inflatable structure at a designated position associated with a tissue structure of a patient;
causing a change in at least one of a volume, a cross-sectional area, or a diameter of the inflatable structure;
determining the change successfully induced a target physiological response;
logging one or more measurements associated with a condition of the tissue structure;
causing a second change in at least one of the volume, the cross-sectional area, or the diameter of the inflatable structure;
determining the second change was unsuccessful in inducing the target physiological response;
waiting for a threshold period of time;
after the threshold period of time, determining the second change successfully induced the target physiological response;
logging one or more second measurements associated with the condition of the tissue structure
reversing at least one of the change or the second change in at least one of the volume, the cross-sectional area, or the diameter of the inflatable structure; and
removing the inflatable structure from the tissue structure.
8 . The method of claim 7 , wherein the tissue structure is an esophagus and the one or more measurements are pressure measurements from a manometer.
9 . The method of claim 7 , wherein the inflatable structure is a balloon.
10 . The method of claim 7 , wherein causing the change in at least one of a volume, a cross-sectional area, or a diameter of the inflatable structure further comprises:
directing air into the inflatable structure or removing air from the inflatable structure.
11 . The method of claim 7 , wherein the target physiological response is at least one of relaxation of a lower esophageal sphincter or peristalsis.
12 . The method of claim 7 , wherein at least the positioning of the inflatable structure and the causing the change in at least one of the volume, the cross-sectional area, or the diameter of the inflatable structure is performed while the patient is sedated.
