1. A woven stent comprising:
a tubular structure having a first end and a second end, wherein the tubular structure defines a lumen extending from the first end to the second end and defines a central axis extending through the lumen in a longitudinal direction of the tubular structure, and wherein the tubular structure comprises:
a plurality of first members;a plurality of second members;wherein the first members and the second members form a braided configuration;wherein each of the first members comprises:
a first body portion extending in a first helical direction around the central axis;a first end unjoined portion extending in a second helical direction around the central axis, wherein the second helical direction is opposite of the first helical direction; anda first end bent portion connecting the body portion to the first end unjoined portion at the first end;wherein each of the second members comprises:
a first end overlap portion extending alongside the first end unjoined portion of a first member; anda second body portion extending from the first end overlap portion in the second helical direction around the central axis toward the second end; anda coating that encapsulates the first end unjoined portions of the first members and the first end overlap portions of the second members.
