Abstract

An in vivo sensing device and system may contain or be used in conjunction with an image sensor and a body lumen clearing element or agent. A method may enable clearing a body lumen for in vivo sensing while using the device of the invention.

Claims

1. A method of using a lumen clearing element for the clearance of a body lumen, said method comprising:

administering into a body lumen a composition containing a lumen clearing element, said lumen clearing element comprising an element selected from the group consisting of;

a coagulant, a flocculant, an aggregant, or a combination thereof.

2. The method according to claim 1, wherein said step of administering a composition containing a lumen clearing element comprises administering the composition in two or more discrete dosage forms.

3. The method according to claim 1, wherein said lumen clearing element is in a form selected from the group consisting of:

a tablet, capsule, lozenge, powder, granule, caplet, solution, suspension, emulsion, or a combination thereof.

4. The method according to claim 1, wherein said method further comprises the step of administering a clear liquid diet, prior to the step of administering the composition containing a lumen clearing element.

5. The method according to claim 1, wherein said method further comprises the step of inserting an in-vivo device into the body lumen, following administering the composition containing a lumen clearing element.

6. The method according to claim 4, wherein said in-vivo device is selected from the group consisting of:

a swallowable imaging capsule, an endoscope, a colonoscope and other intra luminal viewing and imaging devices.

7. The method according to claim 1, wherein said method further comprises the step of administering gut-lavage solutions.

8. The method according to claim 1, wherein said body lumen is the colon.

9. The method according to claim 1, wherein said lumen clearing element is contained in an in-vivo device.

10. The method according to claim 1, wherein said lumen clearing element is incorporated within a coating coated on the surface of an in-vivo device.
