BIOERODIBLE POLYMERIC MEDICAL DEVICE HAVING PHOTO ACTIVE GROUPS

摘要

A medical device includes a tubular network of struts including a bioerodible polymer. The tubular network can include a plurality of bands and a plurality of connector struts. Each band can include a plurality of peaks between adjacent band struts. Each band can be connected to one or more adjacent bands by at least two connector struts at a plurality of connector intersections. The bioerodible polymer can include a plurality of polymer chains functionalized with a photo active group.
