METHODS AND APPARATUS FOR INTRAOCULAR BRACHYTHERAPY

摘要

A method for performing intraocular brachytherapy and an apparatus for performing the same is disclosed. The apparatus preferably comprises a hand- held delivery device that advances a radiation source into an associated cannula or probe that is positioned adjacent the target tissue. The handpiec e provides for shielded storage of the radiation source when retracted from th e cannula and includes a slider mechanism for advancing and retracting the radiation source. The radiation source is mounted to a wire that has a flexible distal end and a relatively stiffer proximal end. A positioning system for the cannula is also disclosed.
