Abstract
A polyurethane-based Shape Memory Polymer was used to develop a surgical stent. Polymer tubes were extruded and trained to transform into a coil upon reaching a temperature of 37?C. The optimum training conditions to obtain maximum recovery consisted of transforming the tube to a coil at 45?C and heat setting it at 90?C for 75 seconds. This stent offers several advantages over conventional metallic stents used in cardiovascular surgeries and additional tests are required to determine its efficacy.
