Description of Invention:
This invention offers a more efficient and accurate photodynamic therapy delivery system that offers to improve the treatment of certain cancers. Presently available spherical-tipped fiber optic systems have fairly large diameters, making it difficult to accurately deliver the laser light to tumor cells while sparing healthy tissue; such probes tend to be fragile, as well. Although standard fluorescent-tipped fiber optic dosimeter probe designs are much smaller and, thus, offer a size advantage, they cannot deliver as much radiation to the tumor as the spherical-tipped models. However, this new fluorescent-tipped fiber optic system produces a strong but narrow response emission, giving it the advantage of being selective as well as effective. It is also more rugged than earlier fiber optic systems.
