Abstract:
1. A stent comprising a matrix of struts disposed parallel to one another comprising: and a bridge connecting a tied cusp of one loop head-to-head with a tied cusp of an adjacent loop wherein all of the free cusps on one end of the end-zone loop and all of the radiopaque markers of the end-zone loop are disposed to touch a notional circle transverse to the longitudinal axis of the stent such that the stress imposed on the stent by a pushing annulus is shared among all of the free cusps and all of the radiopaque markers on the one end of the end-zone loops; wherein the radiopaque markers are distributed around the circumference of the end-zone loops, each of the markers positioned in a gap defined between outer surfaces of adjacent end cusps; and wherein the adjacent struts connected by a tied cusp have different lengths, and at least one free cusp in each loop joins two struts of approximately equal length.
