Method for in vivo sensing
A method for in vivo sensing of a body lumen such as a lumen in the upper GI tract is provided. The method may include, for example, inserting a sensing device into a subject's body lumen, positioning the subject in a horizontal or other suitable position, and receiving data transmitted from the sensing device.
1. A method for in vivo sensing of an esophagus, the method comprising:
inserting an autonomous sensing device into a subject's esophagus while the subject is lying flat in a horizontal position on his right side;
administering one sip of water every 30 sec for 7 minutes to the subject;
positioning the subject in an upright sitting position;
administering an additional sip of water to the subject;
sensing data as the sensing device moves through the esophagus; and
receiving data transmitted from the sensing device.
2. The method according to claim 1 wherein sensing comprises imaging the subject's esophagus.
3. The method according to claim 1 comprising ingesting a saliva reducing agent prior to inserting a sensing device into a subject's body lumen.
4. The method according to claim 3 wherein the step of ingesting a saliva reducing agent comprises ingesting a saliva reducing agent including glycerin.
5. The method according to claim 3 wherein the step of ingesting a saliva reducing agent comprises ingesting a saliva reducing agent including oil.
6. The method according to claim 1 comprising training a patient to drink sips of ˜15 ml of water through a straw.
7. The method according to claim 1 comprising substantially emptying the subject's esophagus prior to inserting a sensing device into a subject's body lumen.
8. The method according to claim 1 comprising receiving data transmitted from the sensing device in real time.
