Endotracheal tubes (ETTs) containing the Sharklet micropattern serve a dual purpose. Sharklet present on the outer surface of the ETT prevents the colonization and migration of bacteria that cause pneumonia and other serious infections. A special Sharklet pattern on the inside is designed to prevent the ETT from occluding with mucus, a common problem with these devices. An ETT that becomes clogged with mucus must be replaced, a painful experience for the patient and a costly procedure for the hospital.
Oct ’14: STI is continuing to work on manufacturing trials of Sharklet patterned ETTs using an NIH/SBIR Phase II grant. We expect to begin clinical trials in 2015.
