About the Bravo pH Monitoring System

The Bravo pH Monitoring System provides valuable diagnostic information about the duration, pattern, and symptom correlation of distal esophageal acid exposure from gastroesophageal reflux:

• The data better reflects patient's physiologic condition when patients maintain regular diet and activities ^1,2



• 48 hours of pH data: double the data of conventional catheter-based tests, increasing the ability of documenting relationships between atypical symptoms and reflux events^2-4



• Better tolerated than catheter-based pH tests⁵

System Components

The Bravo system uses the Bravo pH Capsule with Delivery System, pH Receiver, and Polygram Net^® Software.

Bravo pH Capsule with Delivery System

The pH capsule and delivery system are single-use devices designed to work with the Bravo pH Receiver.

Bravo pH Receiver

This reusable device stores a full 48 hours of pH data transmitted by the Bravo pH Capsule.
