Abstract: A device is configured to transmit tissue conductance communication (TCC) signals by generating multiple TCC signals by a TCC transmitter of the IMD. The generated TCC signals are coupled to a transmitting electrode vector via a coupling capacitor to transmit the plurality of TCC signals to a receiving medical device via a conductive tissue pathway. A voltage holding circuit holds the coupling capacitor at a DC voltage for a time interval between two consecutively transmitted TCC signals.

Abstract: A device, such as an IMD, having a tissue conductance communication (TCC) transmitter controls a drive signal circuit and a polarity switching circuit by a controller of the TCC transmitter to generate an alternating current (AC) ramp on signal having a peak amplitude that is stepped up from a starting peak-to-peak amplitude to an ending peak-to-peak amplitude according to a step increment and step up interval. The TCC transmitter is further controlled to transmit the AC ramp on signal from the drive signal circuit and the polarity switching circuit via a coupling capacitor coupled to a transmitting electrode vector coupleable to the IMD. After the AC ramp on signal, the TCC transmitter transmits at least one TCC signal to a receiving device.

Abstract: A system, such as an IMD system, includes a tissue conductance communication (TCC) transmitter configured to generate a beacon signal by generating a carrier signal and modulating a first property of the carrier signal according to a first type of modulation. The TCC transmitter is configured to generate a data signal subsequent to the beacon signal by generating the carrier signal and modulating a second property of the carrier signal different than the first property according to a second type of modulation different than the first type of modulation.

Abstract: A method and apparatus related to detecting the presence of a power transfer coil implanted in a patient are disclosed. According to the aspect, an external device of a medical implant system is provided, the external device having an external coil and processing circuitry. The processing circuitry is configured to monitor a resonance frequency associated with the external coil. When the resonance frequency changes as a distance between the external coil and an expected location of an internal coil, then the processing circuitry is configured to conclude that the internal coil has been detected. When the resonance frequency ramps up to a steady state value at a rate that falls below a rate threshold, then the processing circuitry is configured to conclude that the internal coil is connected to an internal load.

Abstract: A device includes a tissue conduction communication (TCC) transmitter that generates a TCC signal including a carrier signal having a peak-to-peak amplitude and a carrier frequency cycle length including a first polarity pulse for a first half of the carrier frequency cycle length and a second polarity pulse opposite the first polarity pulse for a second half of the carrier frequency cycle length. Each of the first polarity pulse and the second polarity pulse inject a half cycle charge into a TCC pathway. The TCC transmitter starts transmitting the TCC signal with a starting pulse having a net charge that is half of the half cycle charge and transmits alternating polarity pulses of the carrier signal consecutively following the starting pulse.
