Patent ID: 7491228

Claim:
A stent comprising a first undulating band forming a closed path about a whole circumference of the stent, the first undulating band comprising a series of alternating first peaks and first troughs, the first peaks oriented in a distal directions, the first troughs oriented in a proximal direction, the first undulating band having a first wavelength and a first amplitude; a second undulating band forming a closed path about a whole circumference of the stent, the 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 wavelength different from the first wavelength, the second amplitude different from the first amplitude; a third undulating band forming a closed path about a whole circumference of the stent, the third undulating band comprising a series of alternating third peaks and third troughs, the third peaks oriented in a distal direction, the third troughs oriented in a proximal direction, the third undulating band having a third wavelength and a third amplitude, the third wavelength equal to the second wavelength, the third amplitude equal to the second amplitude; a first plurality of longitudinal first connectors extending between first troughs and second troughs; a plurality of longitudinal side branch connectors extending between second peaks and third troughs; wherein the second undulating band, the third undulating band, and the side branch connectors define a plurality of cells, one of the cells being a side branch opening, the side branch opening being the largest cell.
