  • Patent number: 9039684
    Abstract: A system and method for controllably releasing radiation in percutaneous radiation treatment is provided. In a preferred embodiment, a laser is coupled to an optical fiber that is inserted below the skin or into a vascular lumen to a predetermined point. The fiber is connected to a source of electromagnetic radiation such as a laser, non-coherent radiation source, high power laser diode, LED, and an ultrasonic source. Radiation is then delivered to the treatment site while the fiber is simultaneously drawn out to the entry point. The fiber is manually withdrawn and during this time the radiation is administered in a manner appropriate for the vein being treating in regards to power or energy level. To maintain a constant proper energy density, the speed of withdrawal is measured and sent to a controlling mechanism. The controlling mechanism modifies the power emitted, pulse length or pulse rate to ensure that the vein or tissue receives a consistent dose of energy during manual withdrawal.
