ABSTRACT:
A self-expanding stent is provided for introduction into a cavity of a human body. The stent has a tubular body which is radially expansible and axially retractable between a working state and a resting state. The tubular body has first and second plaited filaments which provide a middle portion of a first diameter and two flared end portions of increasingly larger diameter as they extend away from the middle portion. Each flared end portion has an axial length along a longitudinal axis of the stent which is greater than an axial length of the portion of minimal diameter. Preferably, the middle portion is a single location, with the diameter of the stent increasing in both directions from that location to the ends of the stent. Different shaped stents are disclosed, including stents having generatrices taking the form of line segments angled relative to the longitudinal axis, and generatrices taking the form of a hyperbola segment or a circle arc segment.
