Abstract
An active implantable medical device including, once implanted, a module external to the patient and a module inside the patient, the external module and the internal module being intended to transfer energy and data from one to the other. Also, a method for transferring energy and data, the method being implemented by the active implantable medical device.
Claims14
An active implantable medical device able to be partially implanted in a subject, the medical device comprising, once implanted, an external module outside the subject and an internal module inside the subject, the external module and the internal module being intended to transfer data from one to the other and transfer energy from the external module to the internal module,
- the external module including an external antenna;
- and
- the internal module including:
- an internal antenna defining two terminals,
- an association in series between the two terminals of an internal integrated circuit associated with the internal antenna having an equivalent input impedance with a capacitive part C4 and a capacitor with a capacitance C3 with the ratio
