Abstract

A vascular or endoluminal stent has low surface friction for ease of navigating a vessel, duct or tract of a patient. The stent is configured as a tubular element of biocompatible material having a longitudinal axis, open ends and a multiplicity of openings of generally common shape and size through its wall throughout its length. The openings are bounded by a network of tangentially interconnected, continuous, predominantly longitudinally oriented curvilinear struts, without discontinuity, forming a sidewall of the tubular element. The stent is adapted to be deployed by exertion of outward radial pressure on the tubular element, and when deployed, at least a segment of each strut undergoes a transition to a predominantly transverse orientation relative to the longitudinal axis of the stent.
