A stent for maintaining the patency of a body passage including an elongate flexible body, at least one lumen extending the length of the body, a filament disposed along the elongate flexible body for inhibiting the fracture of the body within the body passage, and a valve for preventing the passage of fluid along the lumen in one direction. The filament is helically wound about the length of the elongate body. Hydrophilic and microbial coatings are applied to the surfaces of the stent and the stent is preferably constructed of a bioresorbable material. |
