Bravo pH Monitoring

Bravo pH Monitoring

If you suffer from chronic heartburn, but you’re concerned about catheter-based pH testing, talk to your doctor about the Bravo pH Monitoring System.


The world’s first catheter-free pH test, Bravo provides a more tolerable and convenient way to evaluate your heartburn symptoms when compared to catheter-based pH monitoring systems.

The capsule is temporarily attached to the wall of your esophagus. The capsule transmits pH information wirelessly to a small receiver worn on your belt or waistband. Data can be transmitted approximately 3 feet, which means you can take the receiver off to shower and sleep without interrupting the test.

Most importantly, a catheter-free test allows you to engage in your usual activities during the test period:

  • Eat normally
  • Bathe and sleep comfortably
  • Maintain your daily life

The Bravo System allows you to perform your normal activities during the pH test, which has the potential to provide a more accurate picture of your acid exposure compared to data collected using catheter-based systems.2 Bravo pH Monitoring Procedure

The catheter-free Bravo pH Monitoring System is revolutionizing pH testing with a capsule that collects pH data and transmits it via radio frequency telemetry to a small external pager-sized receiver worn by the patient.

How the Procedure Works

When you are ready for your procedure, you will be asked to sit or lie back while the physician places the capsule into the esophagus. After the capsule is in place, suction is applied, drawing a small amount of tissue into the capsule. The capsule is then locked into place. The placement procedure is simple to perform and well tolerated by most patients.

The capsule begins measuring the pH levels of the esophagus immediately, transmitting pH measurements wirelessly to a small receiver worn on your waistband or belt. The receiver houses three symptom buttons, and you will be asked to press the corresponding button when you experience heartburn, regurgitation, or chest pain during the procedure. You also will be asked to keep a diary and record periods of sleeping and eating during the procedure.

Upon completion of the procedure,you will return the recording device and diary to your physician, who will upload the data and analyze the results to determine the appropriate diagnosis. The disposable capsule will spontaneously detach and pass naturally through a bowel movement a few days after the test
