摘要：
A flexible stent (10) having a waveform pattern (13) formed from a sheet (11) of biocompatible material (39) and into a tubular shape (12) for maintaining the patency of a lumen such as in a coronary vessel. The waveform pattern of the stent is formed from a flat sheet of malleable, biocompatible material by, for example, photochemically etching the sheet and leaving a framework (44) or plurality of closed cells (17-19). The waveform pattern is formed into a tubular shape around a deflated, delivery catheter balloon (35) with segments (24, 25) of the closed cells being interposed only overlapping a reinforcing member (14) extending longitudinally along the stent. The stent material is treated to reduce the coefficient of friction of the material and to aid in the radial expansion of the stent with the balloon. Radiopaque markers (41, 42) are positioned at the ends (15, 16) of the stent to aid the physician in positioning the stent at an occlusion site.
