Abrasion and blunt tissue trauma study of a novel flexible robotic system in the porcine model.

Objectives: The objective of this study was to determine if a flexible robotic system caused increased tissue reaction when accessing the oropharynx and hypopharynx compared to intubation controls in only 2 scenarios: high speed tissue impact and multiple unit insertions and retractions. The data obtained were submitted as part of the entirety of information submitted for FDA approval.

Methods: This study consisted of 5 groups of Yorkshire pigs (2 animals per group).
