Abstract
An expandable, bioabsorbable stent having a coiled-coil configuration is described. The stent further comprises regions of variable pitch that allow for variation in either rigidity, or variability diameter within sub-regions along the length of the deployed stent. By varying the diameter allows the stent to extend into regions such as branched vessels, or into the neck of aneurysms. In some embodiments, the stent comprises longitudinal support fibers that run substantially the length of the deployed stent to provide additional strength. In addition, the stent may also comprise regional support fibers that run less than the length of the stent, and which provide increased regional strength while permitting flexibility of the stent. The stent further comprises micro-tubes that are configured to be visible using medical imaging techniques. The stent can be manufactured from materials that are bioabsorbable and/or include the ability to release pharmacologically active substances over time.
