Abstract
An expandable stent for use in a body vessel comprises a thin-walled tubular framework including two or more circumferentially adjacent end members extending in a longitudinal direction from an end of the framework. In a delivery configuration of the tubular framework, the end members have an interlocking configuration. Each end member has a first interlocking side and a second interlocking side, where the first interlocking side has a circumferentially directed protrusion and the second interlocking side has a circumferentially directed recess. The protrusion of a first end member mates with the recess of a second end member. In an expanded configuration of the tubular framework, the end members are disengaged from the interlocking configuration. Each end member may be an eyelet including an opening for a radiopaque rivet. A method of preparing the expandable stent for delivery into a body vessel is also described.
