Abstract:
1. A method of measuring blood pressure within a human body, comprising: implanting a pressure sensing assembly into a vessel near the heart in the human body, the sensor assembly including a flexible structure capable of expanding when implanted within the vessel, a first sensor member having a self contained electric power supply coupled to the flexible structure, and a second sensor member having a self contained electric power supply coupled to the flexible structure; wirelessly transmitting a sensor data request message from a pulse generator implanted within the body to the first and second sensor members, the sensor data request message configured to prompt each of the first and second sensor members to transition from a power save state to an initialization state for a predetermined period of time for processing incoming communication data; comparing an address in the sensor data request message against a unique address of the first and second sensor members and, upon receiving a matching address, selectively activating one of the first or second sensor members from the initialization state to an activation state in which a pressure sensor is activated for sensing pressure data; and performing periodic data collection events, including:
