Abstract

An implantable medical device comprising a wireless transcutaneous link is disclosed. The medical device includes an external unit and an implantable unit. The external unit includes an electronic unit operationally coupled to a transmitter coil, a coil unit comprising a loop structure, and a fixation unit configured to attach the loop structure to a user's body i) proximal to an implantable receiver coil, and ii) around a body part of a user such that a part of the body part is positioned in a hollow section of the loop structure. The implantable unit includes the implantable receiver coil, aprocessing unit configured to i) process the received data signal, and / or ii) utilize the received power for operation of at least one of the components of the implantable unit. The wireless transcutaneous link includes a coupling between the transmitter coil and the receiver coil, and when the loop structure is attached using the fixation unit, at least a substantial number of magnetic field lines generated in response to excitation of the transmitter coil passes through the implantable receiver coil.

Description

technical field [0001] The present invention relates to implantable medical devices comprising a transdermal link. In particular, the present invention relates to implantable medical devices such as hearing aids, comprising a wireless transdermal link for transmitting power and / or data thereon, comprising a coupling between a transmitter coil and an implantable receiver coil, Wherein the coupling coefficient between the transmitter coil and the implantable receiver coil is substantially improved. Background technique [0002] Any discussion of prior art in this specification is in no way taken as an acknowledgment that such prior art is widely known or forms part of the common general knowledge in the field. [0003] Medical devices having one or more implantable units, commonly referred to as implantable medical devices, have provided substantial benefits to patients in recent decades. Specifically, devices such as implantable hearing aids, implantable pacemakers, defibri...
