Abstract
A stent includes an elongated stent member having a plurality of post members. Each post member includes a pair of opposite sides. A first end of each post member includes an arcuate apex interconnecting the opposite sides. A second end of each post member has an open end. The opposite sides are angled to converge toward each other at the second end. The second end of each post member is connected to an adjacent post member by a stent portion. Each opposite side and each stent portion converge at an angle of less than 90°. The opposite sides are angled to converge toward each other at the second end.
