A probe has been constructed with which an obstruction of a blood vessel (23, 10) can be treated in an extremely gentle manner without risk of inadvertent destruction of tissue other than the tissue which is intended to be destroyed. A probe according to one embodiment of the present invention comprises an elastic wire (2), the free end (5) of which can be distanced from the main body of the probe (1) and, by passing an electric current through the wire (2), it is possible to achieve a local destruction of the tissue which is pushed by the free end (5) of the electric wire. According to another embodiment of the present invention, the probe can comprise a rotary spiral (2a) which is used as a transport means for the aspiration of the debris, for example a clot (21), the rotary spiral acting as a worm screw. <IMAGE>
