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
