Ophthalmic brachytherapy device
First Claim
1. An ophthalmic brachytherapy device for treating a diseased area with radiation, said device comprising:
- a handle, an applicator head comprising an applicator and a shield;
said applicator coupled with said handle and adapted to receive a source of radiation, said applicator moveable between a first radiation shielded position and a second position wherein radiation is allowed to reach the diseased area;
said applicator comprising a stem and a receptacle, said receptacle located opposite said handle and containing said source of radiation;
the distal end of said applicator having a shape conforming to the shape of the eye globe;
said shield slidably receiving said applicator to contain radiation while said applicator is being inserted and positioned;
the distal end of said shield having a shape conforming to the shape of the eye globe;
an actuator coupled with said applicator and movable between first and second positions corresponding to said first and second positions of said applicator; and
, a light source disposed at the terminal end of said applicator head which illuminates only a targeted radiation zone.

Abstract
A method and apparatus are provided for use in ocular brachytherapy. The device comprises a handle, an applicator coupled with said handle, and adapted to receive a source of radiation. The applicator is movable between a radiation shielding position and a position wherein radiation is allowed to reach the diseased area. A plurality of light-emitting diodes are located so as to define the area to be treated. A shield receives the applicator so as to shield the radiation source during insertion and positioning proximal the treatment site. An actuator moves the applicator between the shielded position and the treatment position. The method of treating macular degeneration employs the device according to the invention.
