Abstract
Apparatus and associated methods relate to diagnostic device and system including a proximal balloon disposed along a length of a catheter and a distal balloon disposed at a distal end of the catheter, with at least one camera disposed at the distal balloon and a pH sensor deployable via inflation of the proximal balloon and configured to engage a patient's esophagus wall to attach the pH sensor to the patient's esophagus wall. In an illustrative example, the pH sensor may be releasably retained to the catheter adjacent to the proximal balloon. The pH sensor may include a tissue engaging feature configured to engage a patient's esophagus wall to attach the pH sensor to the patient's esophagus wall. The diagnostic device may improve upon existing processes by providing a single device to perform a multi-purpose diagnostic procedure.
