APPARATUS FOR PERFORMING THERAPEUTICS TISSUE ABLATION AND BRACHYTHERAPY

摘要

A therapeutic probe and system for treating a tissue margin surrounding an interstitial cavity is provided. The interstitial cavity may be created by resecting tissue, e.g., malignant tissue, from the patient's body to create the interstitial cavity. The interstitial cavity may assume any shape, but in a typical method, the interstitial cavity is spherically shaped. An expandable hyperthermic body of the therapeutic probe is expanded within the interstitial cavity into contact with the tissue margin. The tissue margin is heated with the hyperthermic body, and therapeutic x-ray radiation is conveyed from the hyperthermic body into the tissue margin. Heating of the tissue margin with the hypothermic body may ablate the tissue margin.
