Patent ID: 8239040

Claim:
An electrode catheter for intervention purposes, configured to coupled with a cardiac pacemaker, neurostimulator, ICD electrode, or EP catheter, comprising: an electrode body ( 20 ) comprising an elongate electrode catheter body ( 21 ) having a distal end ( 24 ) and a proximal end ( 26 ); at least one electrode pole ( 23 ) in an area of said distal end ( 24 ) of said electrode body ( 20 ); at least one supply line ( 22 ), which runs insulated in said electrode body ( 21 ) in a main direction (H) from said proximal end to said distal end, to said at least one electrode pole ( 23 ); wherein to desensitize said electrode catheter to radiation of an electromagnetic field radiated by a magnetic resonance diagnostic device of an interfering frequency having a specific wavelength (λ), said at least one supply line ( 22 ) changes run direction at least twice so that three portions of said at least one supply line are situated in a longitudinal portion of said electrode body where said run direction changes at least twice in such a way that said at least one supply line ( 22 ) runs at least once opposite to said main direction (H) and twice along said main direction (H), and a distance (L 2 ) between two direction changes (R) is shorter than approximately half of a wavelength (λ/2) of said interfering frequency; and, wherein said at least one supply line comprises no discrete components including inductors or capacitors within said electrode body ( 21 ).
