    Abstract

    Purpose: To evaluate the characteristics of large-diameter balloon catheters used during endoluminal repair of aortic aneurysms. Methods: Thirty-three large balloon dilatation catheters in the diameter range of 15 to 30 mm were measured at controlled pressures from 1 to 4 atm. The balloons were inflated with water using an inflation syringe connected to a pressure transducer. Diameters at stable pressure and pressure changes against time were recorded for each balloon. Results: Dilation catheters in the range of 15 to 20 mm in diameter were significantly smaller (p < 0.005) than their nominal diameter at 1 and 2 atm; they reached nominal diameter only at the relatively high pressure of 4 atm. Most larger diameter balloons (25 and 30 mm) did not attain their nominal diameter even with pressures up to 4 atm. All sizes of balloon catheters tested became relatively compliant at pressures > 3 atm. Conclusions: The large balloon catheters tested in this study were designed for arterial angioplasty or valvuloplasty. They attained a significantly smaller size than their nominal diameter at pressures < 3 atm and became compliant at pressures exceeding 3 atm. Interventionists should be aware of these characteristics when using balloon catheters such as these during endoluminal graft deployment. Large balloons that reach predictable diameter at lower pressures should be designed specifically for use in endoluminal graft procedures.
