Abstract
Stents having a plurality of serpentine bands including a proximal end portion, a distal end portion, and a middle portion therebetween are herein disclosed. Each of the bands includes peaks and valleys. Serpentine bands of the proximal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. Serpentine bands of the distal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. The repeating pattern of the proximal end portion is different than the repeating pattern of the distal end portion.

A stent comprising:
- a proximal end portion, a distal end portion, and a middle portion therebetween;
- the proximal end portion comprising a plurality of strut columns including first, second, and third strut columns;
- the distal end portion comprising a plurality of strut columns including fourth, fifth, and sixth strut columns;
- each of the first, second, third, fourth, fifth, and sixth strut columns comprising alternating peaks and valleys including at least four peaks and at least four valleys;
- each valley of the first strut column connected to one peak of the second strut column;
- one-half of the total number of valleys of the second strut column connected to peaks of the third strut column in a repeating pattern of connected and unconnected valleys, wherein the repeating pattern of connected and unconnected valleys comprises one connected valley followed by one unconnected valley;
- one-quarter of the total number of peaks of the third strut column connected to the middle portion in a repeating pattern of connected and unconnected peaks, wherein the repeating pattern of connected and unconnected peaks comprises one peak connected to the middle portion followed by three peaks which are unconnected to the middle portion, the connected peaks connected to the middle portion via connecting struts;
- one-quarter of the total number of peaks of the fourth strut column connected to the middle portion in a repeating pattern of connected and unconnected peaks, wherein the repeating pattern of connected and unconnected peaks comprises one peak connected to the middle portion followed by three peaks which are unconnected to the middle portion, the connected peaks connected to the middle portion via connecting struts;
- one-half of the total number of peaks of the fifth strut column connected to valleys of the fourth strut column in a repeating pattern of connected and unconnected peaks, wherein the repeating pattern of connected and unconnected peaks comprises one connected peak followed by a second connected peak, the second connected peak followed by two unconnected peaks;
- each peak of the sixth strut column connected to one valley of the fifth strut column.
