Abstract

A method and system for in vivo detection of H. pylori. The method according to one embodiment includes sensing pH in at least one location proximate to a patient'"'"'s stomach mucus and transmitting by radio frequency pH data to an external receiving unit. The pH data may be part of an in vivo image.

Claims

1. A system for in vivo detection of H. pylori, the system comprising:

an autonomous in vivo sensing device configured for sensing in vivo pH and for transmitting in vivo data to a receiving unit, said sensing device comprising an imager; and

an external receiving unit configured for indicating an in vivo pH, based on the transmitted in-vivo data.

3. The system according to claim 1 wherein the external receiving unit is configured for indicating an in vivo pH about equal or larger than 5.5.

5. The system according to claim 1 wherein the sensing device includes pH indicator.

6. The system according to claim 5 wherein the pH indicator is a color changing indicator.

8. The system according to claim 6 wherein the pH indicator is attached to an optical window in the sensing device.

9. The system according to claim 6 wherein the pH indicator is immobilized within a sampling chamber in the sensing device.

11. The system according to claim 1 wherein the sensing device comprises a radio frequency transmitter.

12. The system according to claim 1 wherein the sensing device comprises a power source.

14. The system according to claim 1 wherein the receiving unit is configured for receiving radio frequency signals.

15. The system according to claim 1 wherein the receiving unit comprises a display configured for displaying transmitted in vivo data.

22. A method for in vivo detection of H. pylori, the method comprising

sensing pH in at least one location proximate to a patient'"'"'s stomach mucus;

and

transmitting by radio frequency pH data to an external receiving unit.

23. The method according to claim 22 further comprising indicating a pH value which is about equal to or exceeds a predetermined threshold.

24. The method according to claim 22 wherein sensing pH is by imaging a color changing pH indicator.

25. The method according to claim 23 wherein the pH value is about 5.5.

27. The method according to claim 23, the method comprising:

inserting an autonomous pH sensing device into a patient'"'"'s stomach;

positioning the patient to achieve substantially covering of the patient'"'"'s stomach body; and

receiving in vivo data.
