Abstract: A rectal balloon apparatus has a shaft with a fluid passageway extending therethrough. A balloon is affixed over an end of the shaft such that the fluid passageway communicates with an interior of the balloon. The balloon has a laterally flat surface thereon when inflated. The laterally flat surface of the balloon has a longitudinal groove formed thereon. The balloon has a radiation sensor positioned within the groove and a plurality of fiducial markers positioned on a surface of the balloon. A stopper is slidably mounted on the shaft.

Abstract: A rectal balloon apparatus has a shaft with a fluid passageway extending therethrough. A balloon is affixed over an end of the shaft such that the fluid passageway communicates with an interior of the balloon. The balloon has a laterally flat surface thereon when inflated. The laterally flat surface of the balloon has a longitudinal groove formed thereon. A valve assembly is affixed to the shaft at an end opposite the balloon. The valve assembly selectively allows a fluid to pass therethrough to move the balloon from a non-inflated condition to an inflated condition. A fluid introducing means is removably attached to the valve assembly to introduce the fluid into the valve assembly.

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.

Abstract: An external immobilizer for cancer treatment has a foot section with at least one inflatable bladder therein, a knee section connected to an end of the foot section, a pelvic section connected to an end of the knee section opposite the foot section, and an inflation device. The knee section has an elevated surface thereon. The pelvic section has at least one inflatable bladder cooperative with a surface thereof. The inflation device is cooperative with the foot section and the pelvic section and is used to selectively inflate the bladders of the foot section and the pelvic section.

Abstract: A rectal balloon apparatus has a shaft with a fluid passageway extending therethrough. A balloon is affixed over an end of the shaft such that the fluid passageway communicates with an interior of the balloon. The balloon has a laterally flat surface thereon when inflated. The laterally flat surface of the balloon has a longitudinal groove formed thereon. The balloon having a pair of bulges formed thereon when the balloon is inflated. A ring is affixed to the shaft adjacent the balloon. The shaft has a plurality of holes formed thereon opening to an interior of the balloon.

Abstract: A gynecological balloon apparatus has a first balloon and a second balloon disposed with a gynecological brachytherapy applicator. The first and second balloons are each movable between an inflated condition and a deflated condition. The first and second balloons may conform to a shape of a vaginal cavity when in their inflated conditions. A radiation detecting sensor and a motion detecting sensor may be positioned with the apparatus.
