Systems, devices, and methods for selectively preventing data transfer from a medical device

An implantable medical device, comprising:

• a memory for recording data;
• at least one physiological sensor that detects physiological information about a patient to produce data;
• a controller configured to:
• detect a patient input received at an external communications device and communicated from the external communications device to the implantable medical device, implanted in the patient, to instruct the implantable medical device to stop recording;
• and
• detect the patient input indicating that data recording should cease, and to cease recording data to the memory upon detecting the input.

An implantable medical device, comprising:

• an implantable communications system that sends and receives signals;
• at least one implantable physiological sensor that detects physiological information about a patient to produce data, the at least one implantable physiological sensor comprising an accelerometer;
• and
• an implantable controller configured to detect an input at the at least one implantable physiological sensor indicating that data transmission should cease, and to cease recording data upon detecting the input, wherein the input includes a signal from the accelerometer received through the communications system resulting from taps by a patient wearing the implantable medical device.

An external repeater device for communicating with an implantable medical device and a remote external device, the external repeater device comprising:

• a communications system that sends and receives signals, the signals comprising patient data received from the implantable medical device;
• a memory that stores patient data received from the implantable medical device;
• and
• a controller configured to:
• detect a patient input received at the external repeater device and, in response, to direct the communications system to generate a communication to the implantable medical device implanted in the patient, the communication configured to instruct the implantable medical device to stop recording;
• and
• detect the patient input indicating that data recording should cease, and to cease recording to the memory the data received from the implantable medical device upon detecting the input.
