Universal balloon for brachytherapy applicator
First Claim
1. A brachytherapy balloon system, comprising a brachytherapy applicator and a brachytherapy balloon, said brachytherapy balloon adapted to fit a vagina, a rectum or an oesophagus and being made of elastomeric polymer and having:
- a) a cylindrical inner surface, said inner surface defining an interior hollow of diameter D with at least one open end into which said brachytherapy applicator of diameter x≦
D can fit, b) an outer surface;
c) said inner and outer surfaces defining an inflatable elongated toroidal shape having a distal end and a proximal end;
d) said distal end having a diameter less than x;
e) a closable means for introducing a fluid into said brachytherapy balloon to inflate said brachytherapy balloon; and
f) a retention ring at said distal end of said brachytherapy balloon that prevents said brachytherapy applicator from protruding beyond said retention ring.

Abstract
A brachytherapy balloon system, including a brachytherapy applicator and a brachytherapy balloon, is described. The brachytherapy balloon is shaped and sized to fit a vagina, a rectum or an esophagus and is made of elastomeric polymer and has a cylindrical inner surface defining an interior hollow of diameter D with at least one open end into which a brachytherapy applicator of diameter x<D can fit, and an outer surface. The inner and outer surfaces of the brachytherapy balloon together define an inflatable elongated toroidal shape having a distal and a proximal end. The distal end has a diameter less than x, a valve for inflating the balloon, and a retention ring that prevents the brachytherapy applicator from protruding beyond the retention ring and reproducibly positioning the applicator on every use.
