Abstract
The disclosed technology relates to a system for delivering UV-A/B light with a catheter to treat infectious or inflammatory disorders in a patient. While UV light in the UV-C range has traditionally been used to treat skin disorders and for focused ablation of plaques in the arteries and other targeted internal uses, it has not been developed for broader infection, inflammation or neoplasia treatment inside the human body. Here, the inventor(s) developed a system for emission of therapeutic doses of UV light via a catheter, capsule, endoscope, tube or port that can be used to manage internal infections and inflammatory conditions inside a patient.
Claims18
A system for performing intra-corporeal ultraviolet therapy, the system comprising:
- a delivery tube,
- wherein the delivery tube is made from borosilicate,
- wherein the delivery tube includes at least an outer layer of transparent material to allow the emitted light to radiate out to internal cavities, and
- wherein the delivery tube is rigid;
- at least one UV light source inside the delivery tube,
- wherein the at least one UV light source is configured to emit light at wavelengths in a UV-A range only, and
- wherein the at least one UV light source is positioned to deliver radiation directed outwardly around a circumference of the delivery tube;
- and
- a power supply connected to the at least one UV light source.
A system for performing intra-corporeal ultraviolet therapy on a patient, the system comprising:
- a delivery tube adapted to be positioned inside an intra-corporeal cavity of a patient,
- wherein the delivery tube is made from borosilicate,
- wherein the delivery tube includes at least an outer layer of transparent material to allow the emitted light to radiate out to internal cavities,
- wherein the delivery tube is rigid, and
- wherein the intra-corporeal cavity is a rectum, anus, mouth, or vagina;
- at least one UV light source inside the delivery tube,
- wherein the at least one UV light source is configured to emit light at wavelengths in a UV-A range only, and
- wherein the at least one UV light source is positioned to deliver radiation directed outwardly around a circumference of the delivery tube;
- and
- a power supply connected to the at least one UV light source.
