We can thus, as I infer from Professor Owen's interesting description of these parts, understand the strange fact that every particle of food and drink which we swallow has to pass over the orifice of the trachea, with some risk of falling into the lungs, notwithstanding the beautiful contrivance by which the glottis is closed.
All of the artificial tracheas were completely healed with the native trachea and functioning normally.
Other recommendations in humans include continued management of stented tracheas with periodic use of balloon dilation or other procedures to continue to maintain a patent airway because of repeated buildup of exudates or obstruction of the lumen by granulation tissue.
Before drug assays were conducted, isolated tracheas were equilibrated in the bath solution for 30-45 min, during which continuous aeration with a mixture of 95% O [sub]2 and 5% CO [sub]2 was applied.
Prior successes included the first ever successful regenerated trachea transplant in 2008, the first successful regenerated trachea transplant using a synthetic scaffold in 2011 and the commencement of the first clinical trial of regenerated tracheas in 2012.

Apart from patients with various respiratory diseases, chemically wounded veterans may also benefit from such tracheas.
is apparently not worried about the safety of the substance and is continuing a human study using chondroitin made by a Spanish company, which imports beef tracheas from non-BSE countries.
Macchiarini has previously performed successful transplants of tissue engineered tracheas, but on those occasions the tracheas used were taken from organ donors and then reseeded with the patient's own stem cells.
