Claim:
1. An endoprosthesis, comprising: an expandable tubular framework having a first end, a second end, and a lumen extending therethrough, the expandable tubular framework being expandable from a compressed state to an expanded state, the expandable tubular framework including: wherein the first, second, third and fourth strut rows have an outer diameter in the expanded state; wherein the first, second and third plurality of connectors extend radially outward in an arcuate pathway beyond the outer diameter of the plurality of strut rows in the expanded state; and wherein the first plurality of connectors extends in a first helical direction, the second plurality of connectors extends in a second helical direction opposite the first helical direction, and the third plurality of connectors extends in the first helical direction; wherein a first end of a first connector of the first plurality of connectors connected to the first strut row is circumferentially offset from a second end of the first connector connected to the second strut row; wherein a first end of a second connector of the second plurality of connectors connected to the second strut row is circumferentially offset from a second end of the second connector connected to the third strut row; and wherein the first end of the second connector is circumferentially located between the first and second ends of the first connector.
