Patent ID: 7471979

Claim:
A system for enhancing absorption of a substance provided on a region of a patient's skin, comprising: a probe configured to provide the substance to the region of the patient's skin, the probe comprising: an array of electrodes provided on a head of the probe; a substance holding unit configured to temporarily hold the substance to be provided on the region of the patient's skin; a plurality of pulse generators configured to generate a sequence of bursts of electrical pulses to the array of electrodes that are disp 6 sed against the region of the patient's skin, so as to provide the bursts of electrical pulses to the region of the patient's skin; a substance applying unit configured to transfer the substance from the substance holding unit to the head of the probe, wherein the plurality of pulse generators are transformers that provide for pulses to be output in alternate polarities in each of the sequence of bursts, and wherein no pulses are output by the pulse generator in between consecutive bursts of electrical pulses, wherein the plurality of transformers include a first set of transformers that provide positive pulses to a first set of the array of electrodes, wherein the plurality of transformers include a second set of transformers that provide negative pulses to a second set of the array electrodes that share no electrodes in common with the first set of the array of electrodes.
