Abstract
A vaginal brachytherapy applicator has an insertable tip section, preferably rigid or at least firm enough to retain its shape when inserted, and a tubular handle section extending proximally from the tip section. A common lumen extends from the handle into and through most of the length of the tip section. In one embodiment the tip section is made of a flexible open-celled foam material with a substantially impermeable outer skin, and in this case the tip section can be contracted, or stretched lengthwise to reduce its diameter, for ease of insertion, then re-expanded to its nominal and working configuration prior to insertion of a radiation source into the lumen and irradiation of tissue surrounding the tip section.
