Abstract

Disclosed herein is a method of fabricating a stent assembly comprising radially expanding a polymeric tube to an optimal degree of radial expansion; fabricating a stent from the expanded polymeric tube; and crimping the stent onto a catheter assembly, wherein the temperature of the stent during crimping is an optimal crimping temperature, wherein the optimal degree of radial expansion and the optimal crimping temperature correspond to an optimal fracture toughness exhibited by the crimped stent upon its deployment as a function of degree of radial expansion and crimping temperature.
