Infrared Thermography as a Support Tool for Developing Shape-memory Polymer Biodevices

Infrared Thermography is a technique for carrying out inspections and non-destructive tests that can also be used as a support tool for developing medical devices based on the use of shape memory polymer materials. This paper sets out some of the opportunities and advantages provided by this technique for designing the heating systems associated with these shape-memory polymer based devices. Its application for developing an active pincer, whose geometry can be changed by heating, is explained in detail. Similar devices can be used as active catheter ends for minimally invasive surgery tasks. These thermography tests can also be used as a validation tool for the heating simulations, linked to optimising this type of devices, and also during “in vitro” tests aimed at obtaining safer active implantable
