Researchers from the ETH Zurich institution have developed a biodegradable airway stent made of biocompatible silicone. The new airway showed positive results in rabbit experiments.
Various situations can occur in people as a result of accidents or various traumas, and these individuals are generally kept open in emergency room conditions. For this job, plastic structures called “Airway” are used. Now, scientists have developed the biodegradable “Airway”, in other words “Airway guidance”.
Nowadays, airway stents are made of silicone or metal materials. Researchers from the ETH Zurich institution have developed a biodegradable airway stent made of biocompatible silicone.
The researchers, who examined the trachea (windpipe) structures with computed tomography (CT-CT), created a 3D digital model of the stent that can be fully adapted to the patient being examined. It was printed in 3 dimensions using a method called digital light processing (DLP).
It should be noted that a kind of resin is used to ensure the flexibility of the developed structure and also contains polymer structures containing gold particles. In this way, the necessary flexibility is provided when placing the relevant airway, and at the same time, the gold particles in its content can be followed by various imaging methods thanks to the airway.
The newly developed airway was tested in rabbits, and according to X-Ray imaging results, the implant was absorbed by the body after 6 to 7 weeks in rabbits.
If the new research can be developed further, it seems likely to be applied in humans. The new research was published in the journal Science Advances.
