Abstract
An intraluminal stent for implanting in a body lumen in which a plurality of connecting members are deformed radially outwardly to form projecting barbs for attaching the stent to a body lumen. The stent has a first, unexpanded low profile diameter for intraluminal delivery, and a second, larger expanded diameter for implanting in a body lumen in which projecting barbs are formed and which penetrate the body lumen to assist in attaching the stent to the walls of the body lumen.
