Abstract

A rectal balloon apparatus comprises a shaft having a fluid passageway extending therethrough. A rectal gas relieving lumen may be positioned with a central shaft for removal of rectal gas. The gas releasing lumen can also or in the alternative be provided along an outer surface of the balloon. 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 method of treating prostate cancer by external beam radiation therapy (XRT), comprising:

a) inserting a prostate immobilizing balloon into a rectum of a patient with a cancerous prostate;

said balloon comprising;

i) a proximal end and a distal end;

ii) a first lumen communicating with an interior of said balloon, said first lumen having a closable valve;

iii) a second lumen extending from past said proximal end of said balloon to past said distal end of said balloon, said second lumen having a capped distal tip and one or more ports adjacent said capped distal tip and distal to said balloon;

iv) said balloon further comprising one or more fiducial markers on a surface thereof;

b) allowing rectal gas to exit the rectum via said one or more ports until no further exiting gas is evident;

c) inflating said balloon sufficiently to compress and immobilize said prostate;

d) determining the position of said one or more fiducial markers and positioning said balloon such that said fiducial markers are in a desired position.

e) treating said prostate with XRT; and

f) allowing rectal gas to exit the rectum via said one or more ports during said treatment.

2. ) A method of treating prostate cancer by XRT, comprising:

a) inserting a prostate immobilizing balloon into a rectum of a patient with a cancerous prostate;

said balloon comprising;

i) a proximal end and a distal end;

ii) a first lumen communicating with an interior of said balloon, said first lumen having a closable valve;

iii) a second lumen extending from past said proximal end of said balloon to past said distal end of said balloon, said second lumen having a capped distal tip and one or more ports adjacent said capped distal tip and distal to said balloon;

b) allowing rectal gas to exit the rectum via said one or more ports until no further exiting gas is evident;

c) inflating said balloon sufficiently to immobilize said prostate;

d) treating said prostate with XRT; and

e) allowing rectal gas to exit the rectum via said one or more ports during said treatment.

3. ) The method of claim 2, said balloon further comprising one or more fiducial markers, and said method further comprises determining the position of said one or more fiducial markers and positioning said balloon such that said fiducial markers are in a desired position.

4. ) The method of claim 2, said balloon further comprising a locking device on said first lumen, and said method further comprising reproducibly positioning and locking said locking device on said first lumen.

5. ) The method of claim 2, wherein:

a) said balloon comprising one or more fiducial markers, and said method further comprising determining the position of said one or more fiducial markers and positioning said balloon such that said fiducial markers are in a desired position;

b) said balloon comprising a locking device and numerical indicia on said first lumen, and said method further comprising reproducibly positioning and locking said locking device on said first lumen.

6. ) The method of claim 2, said balloon further comprising a radiation sensor thereon, said method further comprising measuring a dosage of said XRT with said radiation sensor and stopping said XRT when said measured dosage reaches a desired dosage amount.

7. ) A method of treating prostate cancer, said method comprising:

a) inserting a prostate immobilizing balloon into the rectum of a patient;

i) said balloon being shaped and sized to immobilize a prostate when inflated;

ii) said balloon further comprising a gas releasing fluid passageway extending from beyond a distal end of said balloon to beyond a proximal ends of said balloon, said passageway having a closed distal tip and one or more ports distal to said balloon;

b) allowing rectal gas to exit the rectum via said one or more ports;

c) inflating said balloon sufficiently to compress and immobilize said prostate;

d) treating said prostate plus a margin of surrounding tissue with XRT;

e) wherein said margin is smaller than it would be with a comparable balloon lacking said gas releasing fluid passageway.

8. ) The method of claim 7, said balloon further comprising one or more fiducial markers, and said method further comprises determining the position of said one or more fiducial markers and positioning said balloon such that said fiducial markers are in a desired position.

9. ) The method of claim 7, said balloon further comprising a locking device on said first lumen, and said method further comprising reproducibly positioning and locking said locking device on said first lumen.

10. ) The method of claim 7,

a) said balloon comprising one or more fiducial markers, and said method further comprising determining the position of said one or more fiducial markers and positioning said balloon such that said fiducial markers are in a desired position;

b) said balloon further comprising a locking device and numerical indicia on said first lumen, and said method further comprising reproducibly positioning and locking said locking device on said first lumen.

11. ) The method of claim 7, said balloon further comprising a radiation sensor thereon, said method further comprising measuring a dosage of said XRT with said radiation sensor and stopping said XRT when said measured dosage reaches a desired dosage amount.
