Polyurethanes are a broad family of polymers. These materials have a significant position in the medicalindustry. The use of polyurethanes is unlimited. But it should be kept in mind that polyurethanes are actuallythe best materials for producing devices for specific applications (Figure 1). Accordingly, we provide anoverview of some applications, which may not be exhaustive, but focus on specific processes, debatableresults, and potential for future developments.Cardiac surgeons' equipment shows no significant role for polyurethanes in intra-aortic balloons, bloodbags for ventricular assist devices (VADs), catheters, and pacemaker leads as the most important. The resultsof testing polyurethanes as blood vessels are not yet complete due to the lack of long-term resistance todegradation. Breast implants covered with PU foam are part of the scientific debate. The use of polyurethaneis limited, but these materials have interesting properties. Cardiac dressings and tissue engineering scaffoldsenable new developments.
