3D-printed bioresorbable airway stent
Narrowing of the trachea or the main bronchi due to injury or illness can end very badly. If patients get too little oxygen, they risk suffocating and often need medical help as quickly as possible.
Surgeons insert stents made of medically usable silicone or metal as a way of treating these patients. Although they quickly bring relief, the implants also have disadvantages: Metal stents must be removed surgically with some effort, which is a burden for the patients, while silicone stents often migrate away from the insertion site. The reason for this is that the implants are not adapted to a patient s anatomy.

3D Printing a New Type of Airway Stent

A new type of 3D printed airway stent could make treating upper airway obstructions quicker and safer.
Obstruction of central airways and the impairment of airflow that results from it is a major cause of death in surgery, especially for patients suffering from lung cancer, and because of a major rise in this disease, cases of central airway obstruction (CAO) are also on the rise.
This narrowing or stenosis of the trachea and the passageways that lead from it to the lungs can be combated through the insertion of a stent to widen the passages and restore airflow.

3D-printed bioresorbable airway stent
An ETH Zurich research team is using 3D printing to produce a new type of bioresorbable airway stent. This could greatly simplify the future treatment of upper airway obstruction.
