Kink resistant
Thick-walled nonflammable cuff reflects laser and transfers heatCuff difficult to deflate if punctured Metal may reflect beam onto nontargeted tissue | Polyvinyl chloride (PVC) | InexpensiveNonreflective Maintains shape well Double cuff maintains seal after proximal cuff puncture | Burns vigorously and yields pulmonary toxin (hydrogen chloride)Cuffed version contains flammable material |
Red rubber | Wrapping protects flammable material but dries tubeMaintains structure Nonreflective | Red rubber itself is highly flammableTubes are thick walled |
Silicone rubber | Wrapping protects flammable materialMethylene blue aids in detection of cuff perforation Nonreflective | Contains flammable materialTurns to toxic ash Single cuff is vulnerable to laser damage |
