Patent ID: 8532767

Claim:
A device for medical applications, comprising an elongated conductive element having a proximal end; a distal end; wherein said distal end comprises at least one distal tip electrode; a separating element configured to galvanically separate the proximal end from the distal end; wherein said separating element is configured to be located in a region between said distal end and said proximal end; wherein said region is configured to increase in temperature through absorption of energy from an electromagnetic field by said separating element; wherein the separating element is a transformer, wherein said transformer comprises a transformer core configured to be saturated in a static magnetic field component of the electromagnetic field; wherein said transformer is configured to create a galvanic separation of said at least one distal tip electrode from other regions of said elongated conductive element; and wherein the transformer is capacitively decoupled such that high-frequency currents induced in the elongated conductive element by an alternating field component of the electromagnetic field are substantially mitigated via the transformer.
