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

In the above paragraph, one or more of refers to use of a medical device or a combination thereof. For example, a cochlear implant may be used alone but may also be used in combination such as providing mechanical stimulation by way of bone conduction hearing aid at a first ear and an electrical stimulation by way of cochlear implant at a second ear of the user. In another example, the same user may be utilizing a cochlear implant as well as an implantable cardioverter defibrillator. Other such examples of combinations are within the scope of this disclosure. If the user is implanted with more than one medical device, a single transmitter coil-receiver coil pair may be used for providing data and/or power to the more than one implantable medical devices. In another embodiment, each of the implantable medical device may be provided with a dedicated transmitter coil-receiver coil pair. In either embodiment, the transmitter coil-receiver coil pair refers to the wireless transcutaneous link that is in accordance with this disclosure.
