US 2002/0055770 A1 · Flexible and expandable stent

Abstract

In one embodiment of the invention, a stent may be provided comprising a first undulating band comprising a series of alternating first peaks and first troughs and a second undulating band comprising a series of alternating second peaks and second troughs. The first undulating band has a first wavelength and a first amplitude and the second undulating band has a second wavelength and a second amplitude where the second amplitude is different from the first amplitude and the second wavelength is different from the first wavelength. A plurality of longitudinally oriented first connectors extend between the first peaks and second peaks.
