Abstract
A polymeric stent having a length, an outer surface and a cross-section. A lumen passes through the entire length, the lumen having a surface forming an equivalent diameter in the polymeric stent. The polymeric stent includes a first aqueous-swellable, biocompatible and biodegradable composition (e.g., polymer) having a thickness. The aqueous-swellable and biodegradable polymer retaining structural integrity for at least 1 hours up to thirty days when swollen to between 15% and 500% of its dry diameter and kept moist by a moist aqueous environment. Barrier layers of biodegradable polymer(s) may be used to prevent migration of liquids into the lumen.
