Description

Medical device communication for controlling functions of a medical device system The present application claims the benefit of U.S. provisional patent application serial No. 63/590,369 filed on 10/13 of 2023, the entire contents of which are incorporated herein by reference. Technical Field The present disclosure relates generally to medical devices, systems, and methods for performing inter-device communication to control medical device system functions. Background Various medical devices for delivering therapy and/or monitoring physiological conditions of a patient have been used clinically or proposed for clinical use in patients. Examples include Implantable Medical Devices (IMDs) that deliver therapy to and/or monitor conditions associated with the heart, muscle, nerve, brain, stomach, or other tissue. Some treatments include delivering electrical stimulation to such tissue. Some IMDs may employ electrodes to deliver therapeutic electrical signals to such organs or tissues, use the electrodes to sense physiological electrical signals inherent in the patient (which may be propagated from such organs or tissues), and/or use other sensors to sense physiological signals of the patient. For example, when ventricular tachyarrhythmia (e.g., tachycardia or fibrillation) is detected, an Implantable Cardioverter Defibrillator (ICD) may be used to deliver a high energy cardioversion or defibrillation (CV/DF) shock to the patient's heart. ICDs may detect tachyarrhythmia based on analysis of cardiac Electrograms (EGMs) or Electrocardiographs (ECGs) sensed via electrodes, and may deliver anti-tachyarrhythmia shocks, e.g., defibrillation shocks and/or cardioversion shocks, via the electrodes. As another example, an ICD or implantable cardiac pacemaker may provide cardiac pacing therapy to the heart when the heart's natural pacemaker and/or conduction system fails to provide synchronized atrial and ventricular contractions at a frequency and interval sufficient to maintain healthy patient function. ICDs and cardiac pacemakers may also provide overdrive cardiac pacing, known as anti-tachycardia pacing (ATP), to suppress or convert detected tachyarrhythmias in an effort to avoid cardioversion/defibrillation shocks. In some cases, two or more medical devices may be implanted in and/or worn by a single patient. Each of the two or more medical devices may be individually operable to perform a monitoring function and/or deliver therapy to a patient. Disclosure of Invention The technology of the present disclosure generally relates to techniques performed by a medical device system for controlling functions of the medical device system. The first medical device of the medical device system may be configured to perform a medical device system function and have a priority for performing the function. The first medical device may determine a condition for disabling a function in the first medical device. In response to determining a condition for disabling a function in the first medical device, the first medical device may send a signal to a second medical device of the medical device system. The second medical device may send a reply signal to the first medical device. In some examples, the second medical device may assume control of the first medical device function by enabling the second medical device to perform the medical device function. In one example, the present disclosure provides a medical device system including a first medical device including circuitry configured to perform a medical device system function, communication circuitry, and control circuitry configured to detect a condition for disabling the performance of the medical device system function by the circuitry. In response to detecting the condition, a communication signal is sent via the communication circuit to a second medical device capable of performing the medical device system function, and execution of the medical device system function by the circuit is disabled. The first medical device may include a power source configured to provide power to the circuitry, the communication circuitry, and the control circuitry. In another example, the present disclosure provides a method comprising performing a medical device system function by a first medical device, detecting a condition for disabling the medical device system function performed by the first medical device, and transmitting a communication signal to a second medical device capable of performing the medical device system function in response to detecting the condition. The method may include disabling execution of the medical device system function by the first medical device. In another example, the present disclosure provides a non-transitory computer readable medium comprising a set of instructions that, when executed by processing circuitry of a medical device system, cause the medical device system to perform a medical device system function by a first medical device of the medical de
