摘要

According to an embodiment, a medical device 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 that is configured transmit power and/or data signal over a wireless transcutaneous link, a coil unit comprising a loop structure with the transmitter coil being wound around and along at least a part of length of the loop structure, and a fixation unit configured to attach the loop structure to a user's body i) proximal to an implantable receiver coil that is configured to be implanted within a body part, 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 configured to receive the power and/or data signal over the wireless transcutaneous link, a processing unit configured to i) process the received data signal to control functionalities of at least one of the components of the implantable unit, 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.

說明書

v) an implantable hearing aid comprising a middle ear implant comprising a vibratory unit configured to attach to one of the bones of the middle ear and/or to one of the windows of the cochlea, the vibratory unit being configured to generate vibrations in accordance with the output. A typical, non-limiting, description of such middle ear implant is provided in withdrawn European patent application EP2129428 (Implantable auditory stimulation systems having a transducer and a transduction medium) where the audio processor of the referred application in FIGS. 3 and 4 represents the disclosed electronic unit (FIG. 2, 204), demodulation electronics of the referred application in FIGS. 3 and 4 illustrates at least a part of the disclosed implantable processing unit (FIG. 2, 206), and FMT with transduction medium (FIG. 2) or plunger type transducer (FIG. 3) of the referred application illustrates the vibratory unit (FIG. 2, 208). The referred application is incorporated herein by reference.
