Covered stents with degradable barbs
First Claim
1. A removable stent for providing reinforcement to a selected region of a selected body lumen including a resilient cylindrical layer, the improvement which comprises:
- at least one bioresorbable extrusion exterior from the resilient cylindrical layer for resisting migration of the removable stent when said removable stent is positioned in said selected region of said selected body lumen.

Abstract
The present invention is directed at a removable stent for providing reinforcement to a selected region of a selected body lumen including a resilient cylindrical layer, including at least one bioresorbable extrusion exterior from the resilient cylindrical layer for resisting migration of the removable stent when the removable stent is positioned in the selected region of the selected body lumen. The present invention also includes a temporary implantable endoprosthesis which includes a tubular, radially compressible and axially flexible structure, including at least one bioresorbable extrusion exterior from the resilient cylindrical layer for resisting migration of the removable stent when the removable stent is positioned in the selected region of the selected body lumen.

17. A method of reducing migration of a removable stent comprising the steps of:
-
constructing said removable stent including a resilient cylindrical layer;
placing at least one bioresorbable extrusion exterior from the resilient cylindrical layer of said removable stent on said removable stent;
positioning said removable stent in a body lumen;
expanding said removable stent within said body lumen; and
resisting migration of said removable stent by interaction between said at least one bioabsorbable extrusion and said body lumen. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
