Abstract

A pellet for testing distal colonic and anorectal function. In one embodiment the pellet comprises a bag comprising the exterior of the pellet wherein the bag is comprised of a polymer that is reactive with a catalyst to form a more solid-like substance. In another embodiment, the pellet may comprise one of a grapheme layer, a wavelength transducer, or a magnetically attractive element. In another embodiment the pellet may comprise a telescopic extender and further comprise a telescope bad coupled to the telescopic extender.

Claims (32)

1. A pellet, comprising:

a bag or balloon;

a polymer positioned within the bag or balloon;

a catalyst configured to react with the polymer inside the bag or balloon, such that the polymer becomes more solid-like upon reaction;

a graphene layer disposed on the bag or balloon; and

a rod extending beyond the balloon or bag;

wherein the pellet is configured to be positioned within a mammalian gastrointestinal tract and to obtain data relative to the mammalian gastrointestinal tract when positioned therein.

2. The pellet of claim 1 , wherein the polymer is selected from the group consisting of a silicone elastomer and a hydrogel.

3. The pellet of claim 1 , wherein the polymer comprises a fluid-like substance.

4. The pellet of claim 1 , wherein the polymer comprises two or more of a first liquid, a second liquid, a first chemical, and a second chemical.

5. The pellet of claim 4 , wherein the two or more of the first liquid, the second liquid, the first chemical, and the second chemical comprise polymers that are configured to cross-link when they react with the catalyst.

6. The pellet of claim 1 , further comprising:

a first chemical and a second chemical positioned within the pellet;

wherein the pellet is configured to actively deliver the first chemical and the second chemical within the mammalian gastrointestinal tract.

7. The pellet of claim 1 , further comprising:

one or more wavelength transducers positioned upon the pellet.

8. The pellet of claim 1 , further comprising:

a central stabilizing core rod, and wherein the rod extending beyond the balloon or bag is an extension of said central stabilizing core rod.

9. The pellet of claim 1 , wherein the rod extending beyond the balloon or bag comprises a plurality of circumferentially positioned pressure sensors.

10. The pellet of claim 9 , further comprising:

a distal pressure sensor present at a distal tip of the rod extending beyond the balloon or bag.

11. The pellet of claim 1 , wherein the rod extending outside of the balloon or bag comprises a catheter.

12. The pellet of claim 1 , wherein the rod extending beyond the balloon or bag comprises a series of pressure sensors extending along a portion of a length of the rod extending beyond the balloon or bag.

13. The pellet of claim 1 , further comprising:

a telescopic extender extending from a relative end of the pellet.

14. The pellet of claim 13 , further comprising:

a telescope balloon coupled to said telescopic extender.

15. The pellet of claim 13 , wherein the telescopic extender is configured to inflate with a two-way pump, and wherein the telescopic balloon is in communication with a reservoir of liquid or gas.

16. The pellet of claim 13 , wherein the telescopic extender is operable using a motor coupled thereto.

17. The pellet of claim 13 , wherein the telescopic extender is extendable and retractable.

18. The pellet of claim 1 , further comprising:

a magnetically attractive element within the pellet.
