Release Title:

Simulation of surgical implantation of the Light Emitting Diodes probe at the Children's Hospital of Wisconsin, Medical College of Wisconsin, Milwaukee. The LED probe is approximately 9 inches long and about one-half-inch in diameter. The LED light source consists of 144 tiny pinhead-size diodes that are three-times brighter than the Sun. The probe was developed for photodynamic cancer therapy under a NASA Small Business Innovative Research program grant.

The approximately 9-inch-long Light Emitting Diodes probe is being prepared for surgery at the Children's Hospital of Wisconsin, Medical College of Wisconsin, Milwaukee. The LED probe consists of 144 tiny pinhead-size diodes and is 9-inches long and about one-half-inch in diameter. The small balloon aids in even distribution of the light source. The LED probe can be used for hours at a time and remains cool to the touch. The probe was developed for photodynamic cancer therapy under a NASA Small Business Innovative Research program grant.
