AN APPARATUS AND METHOD OF BIO-ENGINEERING TUBULAR AUTOLOGOUS TISSUE GRAFT

摘要

A novel apparatus and tissue graft for use in regeneration, reconstruction or repairing of urological structures and surfaces, and also a method of culturing tubular autologous tissue graft are disclosed in which urothelial cells are grown on a biocompatible scaffold which Is encircled by biodegradable and/or biocompatible shaped setting material. The biocompatible scaffold is then implanted at a site where tubular structure is to be repaired or replaced. The scaffold is removed, leaving the cells inside, after 2-3 days or after the cells begin to adhere with indigenous urethral tissues.
