Abstract: This paper describes the investigation of heat-setting effects on physical and mechanical properties of prototyped polydioxanone stents made from weft-knitting technology for the treatment of intestinal stenosis. First, a set of stents was knitted on a small diameter, circular weft knitting machine using polydioxanone biodegradable monofilament. Subsequently, the stent was heat-set in order to restore a tubular shape to the stents. Finally, the mechanical properties of the stents were characterized, and their thermal stability following a heat-setting process was evaluated. The results showed that the stents could withstand higher radial forces than two other commercially available stents. A temperature of 80 degrees C and time of 5 minutes were found to be more appropriate for the heat-setting of the stents respectively. In conclusion, the tubular stent was successfully fabricated and it has great potential for the treatment of gastrointestinal stenosis.
