Abstract
An ocular brachytherapy device, generally comprising a catheter and wire, impregnated with radioactive material, are provided. The wire is formed having a desired treatment shape and size such that it can be placed near an area requiring treatment and effectuate treatment while not affecting adjacent areas. For ease in placement near such areas the wire is preferably formed using materials having properties that permit formation into a desired shape while allowing the wire to be straightened for retraction into the catheter, the shape returning upon removal from the catheter. The wire is preferably impregnated with radioactive material. When the catheter is placed near the area of treatment and the wire is pushed out of the catheter, the wire retakes the desired form and provides a therapeutic radioactive treatment to the area. Preferably, the radioactive material is placed on one edge of the wire, such that the radiation can be directed to the affected area, and non-affected areas can be shielded from radiation.
