CardioMEMS HF
System for
Pulmonary Pressure Monitoring in
Heart Failure Patients Approved by FDA (VIDEO)
Heart disease that progresses into
Heart Failure leaves people in a dangerous state in which acute decompensation events can happen any time. Being able to monitor such
Patients day and night **rmally requires hospitalization, but a new implant
System just approved by the FDA can offer capabilities similar to right
Heart catheterization while the patient is back home.
The
CardioMEMS HF
System from*
CardioMEMS (Atlanta, GA)*consists of an implantable, battery-free sensor that is implanted into the distal
Pulmonary artery to continuously measure the
Heart rate along with systolic, diastolic, and mean pressures. The implant is delivered using a matching vascular catheter and readings from the implant are gathered by a bedside electronics unit that also wirelessly powers the implant. The data is transmitted to an online portal where the patient’s cardiologist can check the readings collected by the
CardioMEMS HF.
Some details about the tech**logy inside the implant, according to the product page:
The sensor is a resonant circuit consisting of a capacitor and an inductor. The capacitance of the sensor is a function of the Pressure in the sensor’s environment and the resonant frequency of the sensor is a function of the capacitance and is measured by the electronics unit. Because of the presence of the inductor coil, the sensor can be electromagnetically coupled and the resonant frequency of the LC (inductor-capacitor) circuit can be measured remotely. This allows for wireless communication with the sensor and eliminates the need for a battery.
