Patent ID: 7787948

Claim:
A method of providing a therapeutic stimulation session, said stimulation session having an initiation, a duration and a termination, comprising the steps of: a. performing a load characterization of the electrode-tissue interface at session initiation, using a capacitor having a known capacitance value, to determine an impedance of the electrode-tissue interface and a depth of discharge of the capacitor; b. using said load characterization and at least three clinician input parameters, two of said clinician input parameters being stimulation pulse width and the other stimulation amplitude, to determine a required amount of charge to be transferred to said electrode-tissue interface required for stimulation; c. determining a required delta voltage by dividing said required amount of charge by the capacitance value of the capacitor; and d. generating multiple identical stimulation pulses with minimal power source consumption for the duration of said stimulation session until said termination.
