1. An implantable medical device comprising:
a memory;
stimulation circuitry configured to deliver electrical stimulation to a patient; and
processing circuitry operably coupled to the memory and configured to:
control the stimulation circuitry to output electrical stimulation therapy to a patient via a first electrode combination, wherein the electrical stimulation therapy comprises a first plurality of pulses, wherein the first plurality of pulses are output at a pulse rate; and
control the stimulation circuitry to output a notification stimulation defined by a predetermined pattern of a second plurality of pulses via a second electrode combination, wherein the second plurality of pulses are interleaved with at least some pulses of the first plurality of pulses of the electrical stimulation therapy to maintain the predetermined pattern of the second plurality of pulses,
wherein the notification stimulation comprises an intensity above a perception level of the patient,
wherein the notification stimulation comprises an acknowledgement notification to a communication from the patient, and
wherein the second electrode combination comprises an electrode disposed at an implant site of the implantable medical device.
