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.
