Abstract

A rectal balloon apparatus comprises a shaft having a fluid passageway extending therethrough. A rectal gas relieving lumen may be positioned with the shaft for removal of rectal gas. A motion detecting sensor and a radiation detecting sensor may be positioned with the balloon, the shaft, and/or the rectal gas release lumen.

Claims

1. A rectal balloon apparatus comprising:

a shaft having a fluid passageway extending therethrough;

a balloon affixed over an end of said shaft such that said fluid passageway communicates with an interior of said balloon, said balloon movable between an uninflated condition and an inflated condition;

said balloon in said inflated condition having a central longitudinal groove on a top surface thereof, said groove engaging a prostate when in use;

a lumen disposed with said shaft so as to have an end opening at or beyond an end of said balloon for the movement of rectal gas; and

a ionizing radiation detecting sensor positioned within said groove.

2. The apparatus of claim 1, wherein said lumen positioned on a surface of said shaft.

3. The apparatus of claim 1, wherein said lumen is integral with said shaft.

4. The apparatus of claim 1, said ionizing radiation detecting sensor positioned on a surface of said balloon.

5. The apparatus of claim 1, further comprising a motion detecting sensor positioned on said rectal balloon apparatus for determining the movement of said ionizing radiation detecting sensor.

6. The apparatus of claim 1, further comprising a motion detecting sensor positioned on said rectal balloon apparatus for determining the movement of said balloon surface.

7. The apparatus of claim 1, wherein said ionizing radiation detecting sensor is a semiconductor type sensor.

8. The apparatus of claim 1, wherein said ionizing radiation detecting sensor is a scintillating fiber optics type sensor.

9. The apparatus of claim 1, further comprising a flexible lumen tip with at least one port disposed with said lumen opening.

10. The apparatus of claim 9, further comprising a fiducial marker disposed with said lumen tip.

11. A rectal balloon apparatus comprising:

a shaft having a fluid passageway extending therethrough;

a balloon affixed over an end of said shaft such that said fluid passageway communicates with an interior of said balloon, said balloon movable between a non-inflated condition and an inflated condition;

said balloon in said inflated condition having a central longitudinal groove on a top surface thereof, said groove engaging a prostate when in use;

a lumen disposed with said shaft so as to have an end opening at or beyond an end of said balloon;

an ionizing radiation detecting sensor positioned with said rectal balloon apparatus; and

a motion detecting sensor positioned with said rectal balloon apparatus.

12. The apparatus of claim 11, wherein said lumen is integral with said shaft.

13. The apparatus of claim 11, wherein said lumen positioned on a surface of said shaft.

14. The apparatus of claim 11, said motion detecting sensor for determining the movement of said ionizing radiation detecting sensor.

15. The apparatus of claim 11, said motion detecting sensor for determining the movement of said balloon surface.

16. A rectal balloon apparatus comprising:

a shaft having a fluid passageway extending therethrough;

a balloon affixed over an end of said shaft such that said fluid passageway communicates with an interior of said balloon, said balloon movable between a non-inflated condition and an inflated condition;

said balloon in said inflated condition having a central longitudinal groove on a top surface thereof, said groove engaging a prostate when in use;

a lumen disposed with said shaft so as to have an end opening at or beyond an end of said balloon for the movement of rectal fluid;

a ionizing radiation detecting sensor positioned in said groove; and

a motion detecting sensor positioned on said rectal balloon apparatus.

17. The apparatus of claim 16, further comprising a flexible lumen tip with at least one port disposed with said lumen opening and a fiducial marker disposed with said lumen tip.

18. A rectal balloon apparatus comprising:

a shaft having a fluid passageway extending therethrough;

a balloon affixed over an end of said shaft such that said fluid passageway communicates with an interior of said

balloon, said balloon movable between an uninflated condition and an inflated condition, wherein in said inflated

condition said balloon has a central longitudinal groove on a top surface thereof, said groove being able to engage a prostate when inflated in a rectum, reducing lateral motion of said prostate;

a lumen disposed with said shaft so as to have an end opening at or beyond an end of said balloon for the movement of rectal gas; and

a ionizing radiation detecting sensor positioned on said balloon.
