Evaluating the Clinical Effectiveness of 3D Printing for a Patient-specific Silicone Stent Airway Implant

The Patient-Specific Tracheobronchial Stent is a silicone stent indicated for use in adults that have stenosis of the airway. The subject device takes a CT scan, thresholds out the airway from the other anatomy, and allows the physician to digitally build the stent to his/her desired dimensions. According to the physician's design, a patient-specific stent can be manufactured using rapid prototyping technology. The patient-specific stent is indicated for use with any rigid bronchoscopy/stent application system that fits the design envelope.
