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.

  • viii) implantable deep brain stimulators or implantable nerve stimulators comprising an implantable electrode array configured to be implanted directly or indirectly onto the brain or nerve respectively, the electrode array being configured to deliver the electrical charges in accordance with the output comprising a stimulation pulse. The delivered electrical charges may be utilized to provide brain with information,
  • viii) eye implants or retina implants comprising a camera for capturing images and an implantable electrode array configured to deliver electrical charges in accordance with the captured images,
  • ix) an implantable cardioverter defibrillator comprising an electrode array (usually as electrical pads) configured to deliver electrical charges (for example by way of electrical shock) in accordance with a comparison of monitored rate and rhythm of the heart with a preset number. In this embodiment, the defibrillator may also include sensors in order to monitor the rate and rhythm of the heart,
  • x) an implantable gastric stimulator configured to be implanted in an abdomen of the user and comprising an electrode array that is configured to deliver electrical charges (typically by way of mild electrical pulses) to nerves and smooth muscle of lower stomach of the user, and
  • xi) an implantable brain computer interface system comprising an implantable sensor adapted to capture neural signals in response to brain activity. The system may further include an implantable transmitter coil adapted to transmit the neural signals as data packet over the wireless transcutaneous link to an external receiver coil. The implantable transmitter coil and external receiver coil is described later in embodiments relating to telemetry feedback data.
