<p>The disclosed stent (30) is formed of an elongate, flexible duct having a very thin wall, and a preformed diameter, length and shape. The stent is constructed of a woven tubular structure of multiple strands or elements. The woven tubular structure is thermally set to a predetermined diameter and length so that the 'at rest' or natural condition of the tubular structure is predictable. A retention or holding member (48) can be formed at one or both of the ends of the stent. This retention member can be reduced in diameter for insertion into the body passage. The woven tubular structure provides a path for fluids to flow in and around the stent, while a patent lumen is being developed. The woven tubular structure allows the stent to be extended or stretched over a guide wire or other non-compressive member, to thereby reduce the diameter of the stent for insertion of the stent into a body passage. </p> |
