Patent ID: 8447416

Claim:
A field decoupling element ( 7 , 7 ′, 7 ″) comprising: said field decoupling element configured to couple a first end of an implantable line ( 1 ′) to an implantable medical device wherein the implantable line comprises an elongated line body ( 2 ) and wherein the implantable line further comprises a function conductor ( 4 ) which extends in a longitudinal direction of the elongated line body and wherein the function conductor implements a medical function of the implantable line at least at a second end of the implantable line on an opposite end of said first end; said field decoupling element in electric contact with the function conductor ( 4 ) in a use state; wherein said field decoupling element reduces coupling of the function conductor ( 4 ) to an external field; at least two contacts ( 15 . 1 , 15 . 2 ) within said field decoupling element wherein said at least two contacts are configured to contact the function conductor of the implantable line as well as another conductive element in a patient's body; a switched-mode network that connects the at least two contacts; a cavity within said field decoupling element that connects at least a first contact to a second contact selected from the at least two contacts and wherein the cavity is configured to receive a conductive liquid, which is formed so that in the use state, body fluid from the patient's body can penetrate and establish an electric connection between the at least said first contact and said second contact.
