There are several studies in the literature using ethanol in several types of catheter made of polyurethane. These studies state the type of polyurethane but they do not state the catheter by brand name. For a specific brand, you will need to obtain information in writing from the manufacturer of that brand. Some polyurethane is a problem with alcohol but not all polyurethane. So you have to follow the catheter manufacturers statements about using ethanol in any polyurethane catheter.
