International ClassA61F 002/06AbstractA removable stent for implantation into a lumen in a human body. The stent is made from a soft, flexible fiber having an outer surface. An outer bioabsorbable/degradable coating is applied to the outer surface of the filament causing it to become rigid. The coating softens in vivo through absorption and/or degradation such that the stent is readily passed or removed from the lumen as a softened filament after a pre-determined period of time through normal flow of body fluids passing through the lumen or by manual removal.Field of SearchStent structureHaving multiple connected bodies Stent length remains constant with lateral expansion Having shape memory Helically wound Formed inside natural blood vessel Self-expanding stent Temperature responsive Absorbable in natural tissue Having plural layers Coating Collagen Protein Made of synthetic material Knitted Woven Velour surface Braided Fiber With emboli trap or filter Inserted in vascular system Bioabsorbable Surgical mesh, connector, clip, clamp or band | |
