This abstract first appeared for US patent application 18366973 titled 'ANTI-MIGRATION MICROPATTERNED STENT COATING

Simplified Explanation

- The patent application describes an endoprosthesis, which is a medical device used to support or replace a damaged or diseased body part. - The endoprosthesis has two states: an expanded state and an unexpanded state. - The endoprosthesis includes a stent, which is a tubular structure that provides support and holds the endoprosthesis in place. - The stent has a first end, a second end, an inner surface that forms a hollow lumen, an outer surface, and a thickness between the inner and outer surfaces. - One of the first and second ends of the stent is covered by a stent end covering. - The stent end covering is made of a polymeric coating that includes a base and multiple protrusions. - The base of the stent end covering has a first major surface that faces the outer surface of the stent and a second major surface from which the protrusions extend outwardly. - The first major surface opposes the second major surface of the base. - The protrusions on the stent end covering are arranged in a micropattern. - The patent application also provides methods of making and using this endoprosthesis.


Original Abstract Submitted

An endoprosthesis has an expanded state and an unexpanded state, the endoprosthesis includes a stent, wherein the stent has a first end, a second end, an inner surface defining a lumen, an outer surface, and a thickness defined between the inner surface and the outer surface; and a stent end covering disposed at one of the first and second ends, the stent end covering including a polymeric coating that includes a base and a plurality of protrusions, the base including a first major surface facing the outer surface of the stent, the base further including a second major surface from which each of the plurality of protrusions extends outwardly, the first major surface opposing the second major surface, wherein the protrusions are arranged in a micropattern. Methods of making and using an endoprosthesis are provided.
