Fig. 1From: Temperature-induced configuration changes in hydrogel-coated coils and their relevance in embolization proceduresClassification of HydroCoil configurational changes: Configuration I, minimal curvature of the HydroCoil without reaching a first loop (a); Configuration II, first complete loop without complete curling of the HydroCoil (b); Configuration III, complete HydroCoil curling (c). d shows two different experimental open-fluid immersion chambers with their respective digital thermometer systems (the external thermostat and chronometers are not shown)Back to article page
