Abstract

Balloon dilatation has previously been limited to one inflated balloon diameter per catheter. A new multi-diameter balloon technology (CRE™) allows three distinct, progressive diameters in one balloon dilator. The purpose of this in-vitro study was to compare the diameter size consistency of the new CRE™ to conventional balloon dilators - Achiever™, Eliminator™ and MaxForce TTS™. METHODS: All balloon dilators were inflated in a water bath at body temperature for one minute. Five CRE™ catheters of each balloon size (25 balloons) were inflated to the three listed diameters at the manufacturer's recommended pressure ratings: Catheter #1 - 6mm-7mm-8mm; Catheter #2 - 8mm-9mm-10mm; Catheter #3 - 10mm-11mm-12mm; Catheter #4- 12mm-13mm-15mm; Catheter #5 - 15mm-16.5mm-18mm. Five Achiever™, Eliminator™ and MaxForce TTS™ balloons of each size were inflated to their single diameter at the manufacturer's recommended pressure. All balloons were inflated with an Alliance™ inflation system with pressure gauge. The diameter was measured on all balloons with a Mitutoyo™ Digimatic Indicator - Type IDF-150E. The average diameter and its standard deviation was calculated to determine the consistency of diameters. RESULTS: Balloon Diameters (mm) CRE™ Diam. S.D MaxForce TTS™ Diam. S.D Eliminator™ Diam.

These diameters showed similar diameter consistency to existing single diameter balloon dilation catheter. SUMMARY: Controlled radial expansion balloon dilators offers three progressively larger diameters in one catheter. This modification has the potential to enhance endoscopic balloon dilation.
