Patent ID: 8444688

Claim:
A removable stent for providing reinforcement to a selected region of a selected body lumen, said removable stent including a resilient cylindrical layer, said removable stent comprises: said removable stent in a first state being compressed to a smaller diameter than that of the selected body lumen to move said resilient cylindrical layer to an interior surface of the selected body lumen, and said removable stent in a second state being radially self-expanded; and, at least one bioresorbable barb extending from the resilient cylindrical layer, said at least one barb contacting the interior surface of the selected body lumen when said removable stent is expanded, the contact of said at least one barb with the interior surface of the selected body lumen resisting migration of the removable stent when said removable stent is positioned in said selected region of said selected body lumen, said at least one barb being flexible in a non-longitudinal direction about said stent, and said at least one barb being flexible to be bent around and toward said resilient cylindrical layer about the non-longitudinal direction so as to have both said resilient cylindrical layer and said at least one barb disposed in compression to a smaller diameter than the selected body lumen, and said at least one barb being rigid along one longitudinal direction of said stent, wherein said resilient cylindrical layer includes a woven over and under braided configuration, and wherein a portion of said at least one barb that is not connected to the resilient cylindrical layer is curved towards a first end of said stent to resist migration in said selected body lumen of said removable stent toward the first end of said stent.
