Patent ID: 6993373

Claim:
An invasive device ( 17 ) that is intended to be introduced into an object ( 7 ) that is to be imaged by means of an MDI apparatus, said invasive device comprising a distal end ( 18 ) and is provided with a housing ( 19 ) that extends to the distal end, with a circuit ( 20 ) that is arranged at the area of the distal end, and also with an electrical connection conductor ( 21 ) that is connected to the circuit and extends through the housing, the connection conductor ( 21 ) comprises mutually separated segments ( 22 - i ), each of which is shorter than a predetermined value, and that the separation between the segments is realized by way of frequency-dependent separating elements ( 23 - i ) constructed as cores ( 25 , 26 ) wound on a carrier ( 24 ) in such a manner that magnetic fields generated by current in the cores ( 25 , 26 ) compensate one another, said elements ( 23 - i ) constitute a conductor for LF currents and an isolator for RF alternating current.
