RUA Life Sciences plc announced update on testing of the Elast-EonTM sealed vascular graft range. The presence of cellulose, a non-toxic, natural plant-based material, had been identified during chemical characterisation testing on samples of large bore vascular grafts. After undertaking a full analysis of the possible source, a secondary study was commissioned to test grafts manufactured under revised cleanroom protocols, which has now confirmed that no cellulose was present in leachable extracts from the new graft samples tested. Once the full chemical characterisation report has been received from the third-party test house, the Group will proceed to submit the 510k notification.
