CardioMEMs

The CardioMEMS HF System monitors certain key indicators in heart failure patients. It allows health professionals to monitor their patients remotely.

CardioMEMS includes an implantable sensor that goes into the pulmonary artery, a catheter to place it there and the Patient Electronics System, a unit that pulls information from the sensor and transmits it to a database used by health care professionals.

A physician implants the CardioMEMS System using a right heart catheterization procedure. In a right-heart catheterization, your doctor guides a special catheter (a small, hollow tube) called a pulmonary artery (PA) catheter to the right side of your heart. He or she then passes the tube into your pulmonary artery and places the CardioMEMS sensor there.

Following the procedure, you’ll carry the Patient Electronics System home. The system includes an electronics unit, antenna and pillow. Together, the components of the Patient Electronics System read the PA pressure measurements from the sensor wirelessly and then transmit the information to the doctor. The antenna is paddle-shaped and is pre-assembled inside a pillow to make it easier and more comfortable for you to take readings.

The sensor monitors the pressure in the pulmonary artery. Patients take a daily reading from home or other non-clinical locations using the Patient Electronics System which sends the information to the doctor. After analyzing the information, the doctor may make medication changes to help treat the patient’s heart failure.
