Fig. 1From: Hybrid membranes for the production of blood contacting surfaces: physicochemical, structural and biomechanical characterizationThe steps for obtaining the hybrid membrane. A) Porcine pericardial sample is placed into the metallic frame on the serosa side and fixed. B) The polymeric solution is gently poured over the fibrosa side of the pericardial sample. C) The polymeric membrane as it appears after drying. D) The hybrid membrane obtained by coupling porcine pericardium and Chronoflex ARBack to article page
