What is it?
The CardioMEMS™ is a small, wireless monitoring sensor implanted in the pulmonary artery to directly measure the arterial pressure. The system allows patients to transmit this data from their homes to their doctors allowing for personalized and proactive heart failure management.
The implantable sensor microelectromechanical systems (MEMS) technology. The sensor is powered by radio frequency energy. It is implanted into the pulmonary artery using minimally invasive techniques via a catheter and is designed to last the life of the patient.
The sensor does not have a battery or leads and is very small. Once implanted, the sensor wirelessly sends pressure readings to the external patient electronic system. There is no pain or sensation for the patient during the readings.
At home, heart failure patients use a portable electronic unit and a special pillow containing an antenna to take daily sensor readings. This is a simple process that takes only a few minutes. The patient’s electronic unit is turned on and the patient lies on the pillow. The electronic unit uses audible signals telling the patient to press the button to initiate a reading. The pressure readings are then wirelessly transmitted to a secure website.
