    • In a method and system for establishing a wireless communication session between an implantable medical device IMD and a home monitoring device, the home monitoring device frequently sends communication-initiating signals to an IMD arranged within the body of a patient for establishing a communication session between the monitoring device and the IMD. In order to save energy, RF telemetry circuitry of the IMD is normally set in a low-power, idle mode. Occasionally, the RF circuitry will leave the low-power mode and enter an active mode in which it is able to detect a communication-initiating signal transmitted by the monitoring device. When a communication-initiating signal is detected, the IMD will respond accordingly to the monitoring device and a communication session will be established. In the present invention, the telemetry circuitry of the IMD will be controlled to wake up from low-power mode and enter an active detection mode independently of the transmission of the communication-initiating signals from the monitoring device. Hence, the external monitoring device will frequently transmit communication-initiating signals, but the IMD will only detect a wakeup signal when leaving its low-power mode and entering active mode at a predetermined instant of time.
    • 在用于在可植入医疗装置IMD和家庭监视装置之间建立无线通信会话的方法和系统中,家庭监视装置经常向布置在患者体内的IMD发送通信发起信号,以建立在病人身体之间的通信会话 监控设备和IMD。 为了节约能源,IMD的RF遥测电路通常设置在低功耗,空闲模式。 偶尔,RF电路将离开低功率模式并进入有效模式,在该模式下,它能够检测监控设备发送的通信启动信号。 当检测到通信发起信号时,IMD将相应地对监视设备进行响应,并建立通信会话。 在本发明中,IMD的遥测电路将被控制为从低功率模式唤醒并且独立于来自监视设备的通信启动信号的传输而进入主动检测模式。 因此,外部监视装置将频繁地发送通信启动信号,但是IMD将仅在预定时刻离开其低功率模式并进入主动模式时检测唤醒信号。

    • Telemetry data from an IMD are routinely extracted in order to perform a full prognosis of a patient's condition and to alter the IMD therapy programming if necessary. Typically, while the IMD is inside of the patient, it periodically or continuously collects and stores data into its memory. These stored data can then be extracted by a physician to an external device for further analysis. In addition to the stored telemetry data, the physician may also want to collect real-time telemetry data such as real-time IEGM data or other physiological data while the patient is in the physician's office. However, transmitting telemetry data can consume a high level of power and shorten the battery life of the IMD if not properly managed. Thus, it is advantageous to have built-in features to minimize the possibility the IMD is not transmitting and/or receiving data while it is not being monitored and/or used by the physician for a predetermined amount of time.
    • 常规地提取来自IMD的遥测数据,以便对患者状况进行全面的预后,并且如有必要,改变IMD治疗程序。 通常,当IMD在患者体内时,它周期地或连续收集并将数据存储到其存储器中。 然后可以将这些存储的数据由医生提取到外部设备用于进一步分析。 除了存储的遥测数据之外,医生还可能希望在病人在医生的办公室内收集实时遥测数据,例如实时IEGM数据或其他生理数据。 然而,如果没有正确管理,传输遥测数据可以消耗高水平的功率并缩短IMD的电池寿命。 因此,具有内置特征是有利的,以使得IMD不被传送和/或接收数据的可能性最小化,同时在医疗器官没有被监视和/或使用预定的时间量的情况下。
