1. A device for facilitating passage of a substance through skin on the body of a subject, comprising:
- an electrode, a first portion of which having a first cross-section, and a second portion of which having a second cross-section which is different from the first cross-section, the electrode being adapted to be placed such that the first portion is in contact with the skin; and
a control unit, adapted to drive the electrode to apply an electric current to the skin capable of ablating stratum corneum epidermidis thereof, so as to facilitate passage through the skin of the substance.

Abstract
A device for facilitating transdermal passage of a substance through skin on the body of a subject is provided. The device preferably includes afcn electrode and a control unit. In a preferred embodiment, the control unit is adapted to drive the electrode to apply to the skin a current capable of ablating stratum corneum epidermidis of the skin, so as to facilitate transdermal passage of the substance. The control unit detects generation of at least one spark responsive to application of the current, and modifies a parameter of the current responsive to detecting the generation of the at least one spark.
