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 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.

Abstract: An implantable medical device comprises a communication module that comprises at least one of a receiver module and a transmitter module. The receiver module is configured to both receive from an antenna and demodulate an RF telemetry signal, and receive from a plurality of electrodes and demodulate a tissue conduction communication (TCC) signal. The transmitter module is configured to modulate and transmit both an RF telemetry signal via the antenna and a TCC signal via the plurality of electrodes. The RF telemetry signal and the TCC signal are both within a predetermined band for RF telemetry communication. In some examples, the IMD comprises a switching module configured to selectively couple one of the plurality of electrodes and the antenna to the receiver module or transmitter module.

Abstract: A TETS having an external controller having a power source, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and an implantable blood pump. The implantable controller has a battery configured to receive power from the receiving coil and the external controller is configured to categorize power transfer states based on predetermined thresholds of efficiency and power demand, and user display states (associated with optional configurable notifications) based on the power transfer states and predetermined temperature thresholds of the transmission coil.

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: This disclosure is directed to systems and techniques for enhancing memory interrogations of a medical device by an external device. In some examples, the systems and techniques overcome issues of poor link quality, particularly when the memory stores time-sensitive and critical patient information, by reducing an individual packet size to fit an allotted time period for the transmission. Based on satisfaction of at least criterion for the communication channel, the systems and techniques direct the medical device to transmit, from the memory and over the communication channel, a number of packets comprising duplicate copies of the packetized dataset, wherein a number of the duplicate copies is set to be commensurate with a reduction to the individual packet size.
