Abstract

The present invention concerns a tissue-engineered medical device, as well as a method for the production said medical device, comprising the following steps: providing a polymer scaffold comprising a mesh comprising polyglycolic acid, and a coating comprising poly-4-hydroxybutyrate; application of a cell suspension containing preferably human cells to the polymer scaffold; placement of the seeded polymer scaffold in a bioreactor and mechanical stimulation by exposure to a pulsatile flux of incremental intensity, thereby forming an extracellular matrix; mounting of the graft on a conduit stabilizer and incubation in cell culture medium; decellularisation of the graft in a washing solution; nuclease treatment of the graft; and rinsing of graft. The invention further comprises and various steps of quality control of the tissue-engineered medical device.
