Abstract

A patient device (PD) for wireless data communication with an implant. The PD can be at least in an unpaired state or a paired state. In the paired state the PD is paired to a specific implant specified by an implant's identification code (IIC). The IIC is stored in PD memory. Automatic pairing of the PD to a specific implant is performed upon receiving an incoming data packet containing an IIC when the PD is in its unpaired state with no valid IIC stored in memory. Thus, the PD is tentatively paired to an implant identified by the IIC contained in the incoming data packet by storing the IIC in the memory. Tentative pairing is cancelled if no further communication occurs within a predetermined period of time. A soft paired state is entered if further data communication does occur.
