    摘要: Systems and methods for reducing power consumption in implantable medical devices (IMDs) in which an IMD implantable in an artery monitors blood pressure. A master device monitors a physiological signal, such as respiratory cycle, and instructs the IMD to take blood pressure measurements over a sampling interval, the duration of which is determined by the master device based on the monitored physiological signal. The master device may determine an end-expiration point of the respiratory cycle and send synchronization information to the IMD to further shorten the sampling interval by coinciding the sampling interval with the end expiration point of the respiratory cycle. The IMD may further conserve power by including processing abilities to collect and/or transmit only a subset of data representing the blood pressure signal, for example, systolic, diastolic, and/or mean blood pressure signal values. The blood pressure readings, once taken, may be transferred to the master device.

    摘要: A system and a method of disposing a second sensor module overlying a first sensor module system is described. A first assembly including an expandable anchor and a sensor module is at least partially overlapped by a second assembly including an expandable anchor and a sensor module. If necessary or desired, the functions of the second sensor module can replace the functions of the first sensor module. The sensor module may include a blood pressure sensor.

    摘要: Systems and methods provide for ambulatorily sensing pulmonary artery pressure from within a patient, and producing a pulmonary artery pressure measurement from the sensed pulmonary artery pressure. Power is ambulatorily provided within the patient to facilitate sensing of the pulmonary artery pressure and producing of the pulmonary artery pressure measurement. Acute pulmonary embolism is detected based on a change or rate of change in the pulmonary artery pressure measurement. An alert is preferably generated in response to detecting pulmonary embolism.
