Abstract
The present invention overcomes all the above drawbacks and provides a versatile method for the fabrication of multilayer hollow tubes that uses a layer-by-layer rod dipping approach using different biomaterials. The device enables fine control over fabrication parameters, such as ascending/descending speeds, rod rotational velocity, and crosslinking or polymerization time. All these technologies allows the generation of more complex multilayer hollow tubes such as vessel-like structures, urethral grafting, prostate grafting and the like.
