Abstract
A device and method for printing lumen tissue constructs and a 3D bioprinter are disclosed. The device has a spray sprayhead assembly and a bioprinting platform. The spray sprayhead assembly prints a biological construct on an inner surface of a lumen tissue by the bioprinting platform. Problems, such as, recurrence of thrombus and restenosis of a lumen after the lumen tissue has been transplanted for a long time, can be avoided. The biological reliability of the lumen tissue can be improved.
