Esoflip™ Dilation Catheter
The Esoflip™ ES-320 balloon catheter is indicated for use to dilate esophageal strictures due to esophageal surgery, primary gastroesophageal reflux, or radiation therapy. The Esoflip™ ES-330 balloon catheter is used in a clinical setting to dilate the gastroesophageal junction (EGJ) to treat achalasia.
Esoflip™ catheters have a dilation balloon which acts as a functional lumen imaging probe (FLIP) showing dynamic changes in the geometry of the stricture or EGJ in a real-time image. The catheter connects to an Endoflip™ system, which injects a conductive solution into the dilation balloon placed in the stricture area or the EGJ. The balloon contains an array of electrodes that measure voltage. As the balloon inflates under user control, the Endoflip™ system uses these voltages to estimate the diameter along the measurement area.
The Esoflip™ ES-320 catheter is not suitable for diameter measurements and dilation of strictures smaller than 8 mm or greater than 20 mm.
