The present invention is directed to a stent for use in a bifurcated body
lumen having a main branch and a side branch. The stent comprises a
radially expandable generally tubular stent body having proximal and
distal opposing ends with a body wall having a surface extending
therebetween. The surface has a geometrical configuration defining a
first pattern, and the first pattern has first pattern struts and
connectors arranged in a predetermined configuration. The stent also
comprises a branch portion comprised of a second pattern, wherein the
branch portion is at least partially detachable from the stent body.
