Abstract
Shape memory polymers (SMPs) are a class of polymeric materials used in various medical interventions such as vascular stents. In this work, two SMPs, thermoplastic (TP) and thermoset (TS), have been measured in vitro for the degree of cellular and protein adhesion, their ability to stimulate inflammatory cytokine production, as well as the effects of the SMPs on the haemostatic system. The stimulatory properties of SMPs on neutrophils have also been directly addressed. Based on the studies of SMP biocompatibility as defined by inflammation, thrombogenesis, and the activation of both platelets and neutrophils, the TS and TP SMP materials are unlikely to stimulate an inflammatory response in vivo.
