1. A stent, comprising:
a main body comprising a plurality of rings that form a helix, each of the plurality of rings comprising a plurality of skewed v-shaped elements that each have a first leg and a second leg that is longer than the first leg;
an end ring is shaped to have a plurality of apices of the end ring; and
a transition region;
wherein the plurality of skewed v-shaped elements of a ring of the plurality of rings form a plurality of apices of the ring;
wherein the transition region includes a connection between a corresponding apex of the plurality of apices of the end ring to a corresponding apex of the plurality of apices of the ring;
wherein the transition region includes a plurality of struts that each connect a corresponding apex of the plurality of apices of the end ring to a corresponding apex of the plurality of apices of the ring;
wherein the transition region includes a first gap and a second gap;
wherein the first gap is between a first apex of the plurality of apices of the end ring and a second apex of the plurality of apices of the ring, wherein the second apex is opposing to the first apex, a direct distance between the first apex and the second apex defines a length of the first gap;
wherein the second gap is between a third apex of the plurality of the apices of the end ring and a fourth apex of the plurality of apices of the ring,
wherein a direct distance between the third apex and the fourth apex defines a length of the second gap;
wherein the length of the first gap is different from the length of the second gap;
wherein at least one apex of the end ring is an apex of a tear drop shaped element;
wherein the tear drop shaped element includes a first v-shaped element having legs that are a same length as each other and a second v-shaped element having legs that are a same length as each other; and
wherein the legs of the first v-shaped element of the tear drop shaped element are longer than the legs of the second v-shaped element of the tear drop shaped element.
