Micro motor provided with a stator and a rotor. The rotor contains a number of magnetic poles arranged about the rotor shaft. The micro motor further contains a connector for electrically connecting the stator with a power source. The stator consists of self-supporting current conductor paths, one end of each of the conductor paths being attached to the connector. Preferably one end of the rotor shaft is borne in the connector and the other end of the rotor shaft is borne in the other end of the stator. Guide wire, in particular for guiding catheters, provided with a suchlike micro motor. Near one end of the guide wire a casing of a material which is transparent for sound waves is integrated in the guide wire. Inside this casing are arranged a rotatable acoustic mirror, means, having electrically connecting elements, for generating sound waves and receiving echoes from the sound waves, and a micro motor for permitting the acoustic mirror to be rotated. The guide wire contains wire conductors for electrical connection of the connector of the micro motor and the electrically connecting elements to the other end of the guide wire. |
