Flexible and expandable stent
First Claim
1. A stent having a proximal end and a distal end comprising a first undulating band comprising a series of alternating first peaks and first troughs, the first peaks oriented in a distal direction, the first troughs oriented in a proximal direction, the first undulating band having a first wavelength and a first amplitude, a second undulating band comprising a series of alternating second peaks and second troughs, the second peaks oriented in a distal direction, the second troughs oriented in a proximal direction, the second undulating band having a second wavelength and a second amplitude, the second amplitude different from the first amplitude, the second wavelength different from the first wavelength, and a plurality of longitudinally oriented first connectors extending between first peaks and second peaks.

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.
