The Endonetics GERD Monitor has a sharp and well-implemented design. It is a wireless catheter-free system that receives 48 hours of data from a patient who has received a 45-minute non-evasive outpatient procedure that places a small gelcap to the wall of the patient's esophagus. The whole process is to treat GERD (Gatroesophageal Reflux Disease), the third most common form of chronic pain.
