Device for improving in vivo penetration of molecules into cells, comprising a generator of square unipolar electric pulses, an electrode device electrically linked to the generator, and a means (8) of injecting the active agent into the tissues. The generator is adapted to generate a signal consisting of a series of square pulses at a low and constant voltage (611) in PWM (Pulse Width Modulation) mode in accordance to the form of the required pulses. The signal is used to divide a constant voltage current (631) output by a direct voltage source (530) and generate a current (641) having a required voltage (130). |
