US 2015/0032146 A1 · VARIABLY HEAT-TREATED TUBULAR DEVICES

Abstract

A vascular device may include a tubular element. The tubular element may include a plurality of longitudinal sections. The plurality of longitudinal sections may include a first longitudinal section having a first austenitic finish temperature and a second longitudinal section having a second austenitic finish temperature different than the first austenitic finish temperature. The first longitudinal section may include a first material. The second longitudinal section may include a second material different than the first material. The first longitudinal section may include a first shape set. The second longitudinal section may include a second shape set different than the first shape set. The first longitudinal section may be configured to provide torquability. The second longitudinal section may be configured to provide flexibility. At least one of the first longitudinal section and the second longitudinal section may be shape set to a straight configuration. The tubular element may include a pattern.
