Method and device for the controlled local, non-invasive application of DC pulses to human and animal tissues

In a method for the controlled local non-invasive application of DC pulses to human and animal tissue where pulses are generated by a pulse generator and applied by means of two electrodes, a fixed large surface electrode and a movable point electrode, where the point electrode is moved from one point to another after a controlled duration, the improvement comprising

• said DC pulses being rectangular pulses having a frequency of from 10 Hz to 10 kHz, a pulse width of from 50 .mu.s to 250 .mu.s and a amplitude less than or equal to 25 V;
• substituting a multipoint electrode for said point electrode, said multipoint electrode comprising a plurality of point electrodes mounted in a support and being electrically isolated from each other;
• applying said multipoint electrode so that substantially all of said plurality of point electrodes simultaneously contact a treated region;
• providing switching means in series between said pulse generator and said multipoint electrode so that one or more of said plurality of point electrodes are sequentially selectable for connection to said pulse generator;
• switching said switching means according to a controlled duration.
