Abstract
Described herein is a braided stent having have a plurality of different segments that can reduce or eliminate foreshortening and allow the proximal end of the stent to more reliably open when deployed in a curved vessel. The segments can be connected together by interlocking loops positioned at the end of each segment and can be formed of one or more radially progressing wave patterns.

A woven stent, comprising:
- a middle portion comprising a helical pattern, wherein the middle portion comprises a plurality of open cells;
- and
- a first intermediate portion attached to a proximal end of the middle portion, wherein a wire of the first intermediate portion is woven through one or more of the plurality of open cells of the proximal end of the middle portion, and wherein a proximal end of the first intermediate portion comprises a plurality of first end loops.
A woven stent, comprising:
- a middle portion;
- a first intermediate portion attached to a proximal end of the middle portion;
- a second intermediate portion attached to a distal end of the middle portion;
- a first terminal portion attached to a proximal end of the first intermediate portion;
- and
- a second terminal portion attached to a distal end of the second intermediate portion;
- and,
- wherein each of the middle portion, the first intermediate portion, the second intermediate portion, the first terminal portion, and the second terminal portion are woven in an over/under helical pattern.
