Device for reducing the fault susceptibility of elongated implants

摘要

An implantable line having an elongated line body, a function conductor extending in the longitudinal direction of the line body, acting to implement a medical function of the line, whereby in addition to the function conductor, a field decoupling conductor which extends over at least a section of the length of the line body essentially parallel to the function conductor is provided, thereby reducing the coupling of the function conductor to an external field.

主权项

1. An implantable line (1) comprising:
an elongated line body; at least one electrode comprising
a tip electrode and a ring electrode anda first and second electrode terminal contact at opposing ends of the elongated line body; a first and second function conductor (13, 15) which extend in a longitudinal direction of the elongated line body that implement a medical function of the implantable line; wherein the first and second function conductor (13, 15) connect the tip electrode and the ring electrode to the first and second electrode terminal contact respectively; a field decoupling conductor (24″) which extends at least between said at least one electrode to said first and second electrode terminal contact wherein said field decoupling conductor (24″) reduces coupling of the function conductor (13, 15) to an external field wherein said field decoupling conductor is configured to terminate at a proximal end of said elongated line body within a header of an implantable medical device wherein said field decoupling conductor is a conductive liquid configured with a volume of liquid to decouple the function conductor (13, 15) to an external field; and, wherein said field decoupling conductor that is said conductive liquid does not electrically couple said at least one electrode comprising said tip electrode and said ring electrode to said first or said second electrode terminal contact.
