For patients with tracheal resection, various composite scaffolds have been developed and applied for tracheal defect repair in animal models. And artificial prostheses consisting of a polypropylene mesh tube reinforced with a polypropylene spiral have been developed and applied clinically.
In this study, a novel three-dimensional (3D) bellows scaffold with high flexibility and biodegradability was developed for tracheal reconstruction. And the flexibility of the bellows scaffold against compression was evaluated using finite element method (FEM) simulation. The bellows scaffold was fabricated by indirect micro-stereolithography technology that combines projection based micro-stereolithography and sacrificial molding process using polycaprolactone (PCL).
