Photonic device and method for treating cervical dysplasia
View Patent ↗A method and device used for treating body cells affected by abnormal cell growth or by oncogenic viruses. In particular the invention relates to photonic device for treating gynecological problems comprising at least one light source incorporated into the irradiation head or into the hand piece or as a external unit connected by light guide. The light source used in the photonic device has a LED, Laser or lamps. This photonic device is used for treating a subject having unwanted cell proliferation, example dysplasia of the portio and/or cervix with Photodynamic therapy (PDT). The advantage of using LED device is, for its radiation safety, cost effectiveness and is easy to handle compared to laser system. A drug applicator is also described which is employed for homogenously application of photoactive drug in the affected area.
1. A treatment set for providing photodynamic therapy to hyperproliferative tissues in gynecological areas, comprising:
a source of radiation;
an applicator, said applicator having
a shaped reflector head for applying radiation from the source to a portio area; and
a tube comprising a tubular wall, said tube attached to said shaped reflector head and extending beyond said reflector head for a sufficient distance so as to be able to expose the cervix channel to radiation from said source;
wherein the tube is adapted to transmit radiation from said source through the tubular wall to the cervix channel.
2. The treatment set according to claim 1 , wherein said source of radiation is attached to said shaped reflector head.
3. The treatment set according to claim 1 , wherein said source of radiation is located externally from said reflector head.
4. The treatment set according to claim 3 , wherein said source of radiation is located in a handle which is attached to said shaped reflector head.
5. The treatment set according to claim 3 , wherein said source of radiation is located externally in a unit communicating to said applicator by light guides.
6. The treatment set according to claim 1 , wherein said source of radiation is selected from the group consisting of LEDs, laser diodes, and lamps.
7. The treatment set according to claim 6 , wherein said LEDs are located about an inside surface of said shaped reflector head.
8. The treatment set according to claim 1 , wherein said tube has a plurality of scattering centers therein for outputting said radiation.
9. The treatment set according to claim 1 wherein said applicator further is a drug applicator comprising of a semi-spherical body and cylindrical tube used for drug application into cervical and surrounding areas affected by hyperproliferative cells.
