1. A prosthetic valve comprising:
a valve body, which (a) is tubular, (b) has an upstream end, a downstream end, and a central longitudinal axis, and (c) defines a lumen along the central longitudinal axis; and
a plurality of prosthetic leaflets, disposed within the lumen, and configured to facilitate one-way movement of fluid through the lumen in an upstream-to-downstream direction,
wherein the valve body comprises struts arranged in a cellular structure defined by first and second circumferential rows of four-sided closed cells,
wherein each of the four-sided closed cells of the first and the second circumferential rows is defined by some of the struts, which are shaped so as to collectively define the following four sides: a left upstream side, a right upstream side, a left downstream side, and a right downstream side, the struts joined at four corners of the four-side closed cell as follows:
the left upstream side is joined to (a) the right upstream side at an upstream corner of the four-sided closed cell and (b) the left downstream side at a left corner of the four-sided closed cell, and
the right downstream side is joined to (a) the left downstream side at a downstream corner of the four-sided closed cell and (b) the right upstream side at a right corner of the four-sided closed cell, and wherein each of the four sides of each of the four-sided closed cells is double-strutted.
