Patent attributes
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.
