The device of reception of signals issued by an implanted active medical device

摘要

This device comprises means of signal collectors for the reception of a magnetic induction, comprising a useful component (bs) emitted by the implanted device (26) and a parasitic component (bp) of external origin. & br / according to the invention, the wave collector means comprise at least one receiver reel (12) which is wound on a first portion (14) of a magnetic circuit and at least one compensation coil (22) which is wound on a second portion (20) of the magnetic circuit, these two portions of the magnetic circuit belonging to a common magnetic element (16) and being configured in such a way that, when the collector means are arranged in a screw - to - screw of the implanted device, the receiver coil is essentially through a single operation by the magnetic induction field lines of the useful component (b) and the compensation coil is traversed essentially two times, in opposite directions, by this same induction.
