Measure and monitor gastroesophageal pH with Bravo™

Bravo™ calibration-free provides information to help establish the GERD diagnosis.1
  • Up to 70 percent of patients with GERD do not have evidence of erosive changes on endoscopy.2
  • The system provides greater sensitivity than endoscopy and higher specificity than therapeutic trials with PPIs.1
  • Patients maintain regular diet and activities during the procedure, so testing is done under normal physiologic conditions.3
  • Tolerance and satisfaction with catheter-free pH monitoring are high in patients who had previously failed catheter-based pH; catheter-free pH monitoring assists in the definitive diagnosis of GERD in this group.4

1 in 3 patients referred with ongoing symptoms while using PPIs doesn't have GERD.5

There are many recent advances in the diagnosis and management of GERD. Prolonged wireless pH monitoring has value on clinical reflux monitoring to enable the assessment of predominant exposure patterns and aid in the diagnosis of GERD.1

Among patients with heartburn, endoscopy with ambulatory reflux monitoring (off PPI) optimizes cost-effective management.6

The most cost-effective diagnostic approach to managing patients with typical
GERD symptoms of heartburn that lack alarm symptoms and fail an empiric PPI is to offer endoscopy with ambulatory reflux monitoring followed by a trial of PPI discontinuation for patients without erosive findings.6

See the current GERD diagnosis and management guidelines from the American College of Gastroenterology and the American Gastroenterology Association.

Our product portfolio 

Bravo™ calibration-free reflux capsule

Use the Bravo™ calibration-free reflux testing system for gastroesophageal pH measurement and monitoring of gastric reflux. The capsule can be attached following either endoscopy or manometry and doesn't require pH calibration. 

Bravo™ reflux recorder

The patient wears the recorder for up to 96 hours while the capsule is detecting reflux events, to record reflux data and patient activity.

Reflux software v6.1

Our reflux software supports the upload and analysis of pH and pH-impedance data collected from the Bravo™ reflux recorder and the Digitrapper™ reflux recorder. The reflux software also allows for extended recording times up to 96 hours5 via the Bravo™ calibration-free reflux testing system.
