Abstract In this paper the photothermal design aspects of novel shape memory polymer (SMP) microactuators for treating stroke are presented. A total of three devices will be presented: two interventional ischemic stroke devices (coil and umbrella) and one device for releasing embolic coils (microgripper). The optical properties of SMP, methods for coupling laser light into SMP, heating distributions in the SMP devices and the impact of operating the thermally activated material in a blood vessel are presented.
