Endoprosthesis (10), in its expanded configuration, comprises a generally tubular structure formed from one or more fibers (12). One or more fibers (12) comprise fiber points of intersection (14). Prior to deployment, fibers (12) comprise a photocurable coating (15), at or near points of intersection (14), in semicured form. Following delivery and expansion of the endoprosthesis (10) by suitable means, the delivery catheter (not shown) is replaced by ultraviolet light delivery catheter (18). Ultraviolet radiation is delivered via ultraviolet light delivery catheter (18) and the photocurable coating (15) is cured. Ultraviolet light delivery catheter (18) is then removed from the vessel, and endoprosthesis (10) is left in place.
