Patent ID: 8818509

Claim:
An implantable element configured to implement a medical function comprising: a main body that is elongated; a functional conductor which extends in a longitudinal direction of the main body in which the functional conductor and main body are separate elements, or form said main body in which the functional conductor and main body are a single element, and which comprises an inductive section that comprises a magnetic flux generation element configured to generate a magnetic flux, and an insertion or attachment element configured to accept said magnetic flux generation element surrounding the functional conductor or proximally to said inductive section; and, wherein said magnetic flux generation element is magnetically coupled to the functional conductor such that the magnetic flux generated upon a current flux through the functional conductor is counteracted and a current flux density through the functional conductor is thus reduced; wherein said magnetic flux generation element comprises multiple sections configured to various frequencies of an external field, and adapted separately to different frequencies; and, wherein said magnetic flux generation element is settable to a predetermined active frequency in an implanted state of the implantable element; and a mechanical adjustment element configured to change a relative position between the inductive section of the functional conductor and the at least one flux generation section of the magnetic flux generation element.
