Patent ID: 7986997

Claim:
A method of establishing communication between an electromedical implant and an external patient device, said method comprising: where said implant and said patient device are not initially synchronized with each other for communication, switching between an activity phase and an activity pause of a transmitting unit of said external patient device in periodically alternating relationship; switching, in periodically alternating relationship, between an activity phase and an activity pause of a receiving unit of said electromedical implant, wherein said activity phase of said transmitting unit of said external patient device is shorter in time duration than said activity pause of the receiving unit of the electromedical implant, ensuring that a relative temporal position of the activity phase of the implant and the activity phase of the external patient device is continually displaced relative to each other such that, within a predetermined maximum time, a temporal overlap occurs between the activity phase of the implant and the activity phase of the external patient device; said implant receiving a recognition signal from said external patient device during said temporal overlap; and switching off said receiving unit of said implant to enter said activity pause of said receiving unit for a defined period of time in response to receiving said recognition signal.
