Abstract

Abstract This device for applying therapeutic radiation serves as a carrier for a selected radiation source that can be inserted into the device to provide a controlled intensity and location of the radiation source. The device can then be inserted into any bodily canal and oriented to bring the radiation source into close proximity to that portion of the bodily canal requiring therapeutic radiation treatment. The location of the radiation source within the device is possible because the device contains a criss-cross, non-intersecting pattern of channels internal to the device. The radiation source can be positioned at any location along any of the channels. The device can be constructed of several members so that a number of members can be connected to form a device of the desired length.
