Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.
