Sealed patches containing radioactive phosphorus-32 that deliver beta radiation to the cancer site were custom-made according to the shape and size of each patient's skin cancer lesions.
Michelangelo Delfino, Ph.D., MoBeta, Inc.'s vice president and co-inventor stated, "Ours is a chemically bonded radioactive surface in which the pure beta-radiation emitter phosphorus-32 is conformally distributed on the stent or alternatively confined to the distal ends, for example, to produce a more selective and localized source of healing radiation." Beta radiation has shown desirable effects in the treatment of restenosis, the regrowth of scar tissue associated with balloon angioplasty failure.
