Abstract

The biocompatibility of a new heparinizable material based on polyurethane and poly(amido-amine) (PUPA) was evaluated both in the heparinized and non-heparinized forms. The quantity of heparin present on the material was measured using radiolabelled heparin and biological tests. Heparin release in plasma from heparinized PUPA was investigated using in vitro methods. The behaviour of PUPA towards cellular and plasmatic blood components was studied. The influence of sterilization on the cytocompatibility response of both heparinized and non-heparinized PUPA was investigated; γ-rays were found to be a suitable method of sterilization as no toxic response was noticed. © 1994.
