What is it indicated for?

The FLEXILOG™ LS, Esophagedl Sphinctor Locator, is to be used for the manometric location of the lower and upper esophageal sphincters. That is the measurement of the distance from the nares to the sphincter.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
