Other, evaluation results: one custom bivona tracheostomy tube was returned for investigation in used condition.The investigation determined that the eyelet was nicked/cut, which propagated into a tear.The instructions for use advise to guard against product damage by avoiding contact with sharp edges.Some tracheostomy tube holders contain velcro or metal clips which may have sharp edges.These sharp edges can come into contact with the eyelets and compromise the product integrity.While the product complaint (torn eyelet) was confirmed, a definitive root cause was not established.
