Abstract:
1. A device for photodynamic stimulation of human cells, comprising: a base housing containing a control mechanism and a pulse generator; and at least one applicator equipped with at least one pulsed first light source connected to said pulse generator; wherein: the generator is configured to selectably supply electrical pulses at a frequency between 200 and 20,000 Liz., a pulse length between 2 and 200 microseconds, and an amplitude of between 2 and 25 volts; the at least one first light source is a semiconductor diode which emits light of approximately 600, 900, and 1200 nanometers in response to said pulses from said generator; and wherein the at least one applicator comprises sensors connected to the control mechanism for measurement of reflected light for feedback control and automatic adjustment.
