A stent and stent delivery system with a catheter and stent operably coupled
to
the catheter. The collapsible stent includes a first end region opposed to a second
end region. A plurality of elongated elements is arranged in a generally zig-zag
fashion between the end regions. A plurality of loops formed at an overlying intersection
of adjacent elongated elements is positioned at each of the end regions. The tips
of the plurality of loops in the first end region form a first end circle. The
loops are arranged in a twist formation when the stent is in the collapsed configuration.
The twist formation includes each of the loops being oriented at a twist angle
measured in a first end plane defined by the first end circle between a line tangent
to the first end circle perpendicular to a radius line from the longitudinal axis
of the stent to a tip of the individual loop being measured, and a loop line longitudinally
dividing the individual loop.
