Devices, systems and methods for delivering and positioning an implantable medical device and for evaluating an acoustic communication link are disclosed. An illustrative system includes a catheter adapted to contain an implantable device with a biosensor and an acoustic transducer configured to transmit an acoustic signal, and an implant assist device in acoustic communication with the implantable device via an acoustic communication link. The implant assist device includes an acoustic transducer adapted to receive the acoustic signal transmitted by the implantable medical device, and control/processing circuitry configured to evaluate a performance of the acoustic link.

Power supplied to a particular telemetry system of an implantable device having multiple telemetry systems is managed by a state machine. Power to a transceiver of a device is terminated if the particular telemetry system remains dormant or inactive for a programmable period of time and power to the transceiver is turned on if a particular signal is received by the implantable device.

The selection of one communication channel from a plurality of available channels is determined by a state machine. In an automatic selection mode, a first telemetry system has priority over other telemetry systems. A communication session is in progress based on session initiation and termination triggers. An override function allows manual selection of a telemetry system.
