Device and method for intracavitary cancer treatment

摘要

A device and method for treatment of cancerous tissue from a body conduit involves insertion into the body conduit of a probe including an energy-emitting element for delivering ionizing energy. The body conduit is dilated to decrease a distance between at least a portion of the body conduit and the cancerous tissue. Ionizing energy is delivered from the energy-emitting element to selectively injure the cancerous tissue, with dilation of the body conduit minimizing the radiation dose delivered to the body conduit for a given radiation dose delivered to the cancerous tissue.
