Patent ID: 7945321

Claim:
An apparatus for performing transdermal drug delivery to be provided to a patient's skin, comprising: a dermabrasion unit for performing a dermabrasion treatment of the patient's skin so as to lower a skin impedance to below a predetermined value; and a probe configured to provide at least one burst of electrical pulses to the patient's skin, the probe including: a transformer configured to create the at least one burst of electrical pulses to be provided to the patient's skin, wherein each pulses in the at least one burst of electrical pulses is stabilized with respect to a current amount by way of a resistor coupled between the transformer and a supply voltage; and at least one electrode provided on a head of the probe and configured to receive the at least one burst of electrical pulses from the transformer and to provide the at least one burst of electrical pulses to the patient's skin; means for determining an impedance of the patient's skin at a same time that the at least one burst of electrical pulses is provided to the patient's skin; and means for controlling an amount of current provided in the at least one burst of electrical pulses so as to control the impedance of the patient's skin to be below a predetermined impedance value, wherein a second resistor is connected in parallel with a secondary winding of the transformer.
