Problems solved by technology

However, it is generally found that increasing the radial force above a certain critical value results in little anti-migratory effect, while a large increase in inflammation results in subsequent tissue granulation tissue
This will make the stent difficult to remove and may cause redness and swelling

Abstract

The invention is directed to an anti-migratory stent comprising a tubular structure having an exterior surface and a plurality of protrusions provided on the exterior surface. The plurality of protrusions includes a first set of protrusions and a second set of protrusions. Each of the first and second set of protrusions includes a base and an apex. The apex of each of the first set of protrusions is offset from the base of the first set of protrusions in a direction opposite a direction of offset of the apex of each of the second set of protrusions from the base of the second set of protrusions.
