US Patent 10004617 Woven stent device and manufacturing method

A stent and method for treating an end of a pre-woven stent is provided. The method includes providing a pre-woven stent including a plurality of sharp ends. A pair of wire portions that extend in opposite helical directions around the stent are bent and woven into the stent to define a pair of overlapping crown portions. When the wires are woven into the stent a double weave portion of the stent is defined. The wires can be cut to define tail portions that are removed from the stent, leaving a single crown portion. The sharp ends can be alternatively treated by curving the ends to define rounded looped ends.
