Abstract
A stent including a cylindrical member having an outside diameter, a length and having proximal and distal extremities. The stent is formed of a metal and has a wall defining a central bore having a longitudinal axis extending from the proximal extremity to the distal extremity. The cylindrical member has at least two longitudinally spaced-apart struts extending in the wall and permit radial expansion of the cylindrical member from a contracted condition to an expanded condition. Ribs extending in the wall prevent shrinkage in length of the cylindrical member as it is expanded from a contracted position to an expanded position.
