In this study, monofilament tubular braided structures were fabricated and their performances were analyzed. The braided tubes are in three-dimensional form, made of polyester monofilaments intended for use in medical applications. This type of structure, called a stent, is used to open clogged arteries and veins by exerting radial forces. The radial force of a braided tube basically depends on three variables: braid angle, helical length, and braid diameter. The mandrel diameter influences the axial and radial forces obtained from the braid tube. In order to assure a stable structure, the braided fabrics were heat-set. Analysis of variances showed that heat-setting temperatures and heat-setting times of braided fabrics exhibited no significant effects in the range in which the tests were performed.
