Prosthetic heart valve
First Claim
1. Apparatus, comprising:
- a valve body that;
is tubular,has an upstream end, a downstream end, and a central longitudinal axis, anddefines 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 has a cellular structure defined by a plurality of joists connected at a plurality of nodes, the joists and nodes delimiting cells of the cellular structure, the plurality of nodes including minor nodes at which 2-4 joists are connected, and major nodes at which 6-8 joists are connected,the cells of the cellular structure comprise a first circumferential row of first-row cells, each of the first-row cells (i) being connected to each of its circumferentially-adjacent first-row cells at a respective one of the major nodes, and (ii) being longitudinally delimited by two of the minor nodes,the cellular structure further comprises a second circumferential row of second-row cells, each of the second-row cells (i) being connected to each of its circumferentially-adjacent second-row cells at a respective one of the major nodes, and (ii) being longitudinally delimited by at least one of the major nodes, andeach of the first-row cells and each of the second-row cells is delimited by exactly four nodes.

Abstract
A tubular valve body has an upstream end and a downstream end, and has a central longitudinal axis, and defines a lumen along the axis. Prosthetic leaflets are disposed within the lumen, and are configured to facilitate one-way movement of fluid through the lumen in an upstream-to-downstream direction. The valve body has a cellular structure defined by a plurality of joists connected at nodes, the joists and nodes delimiting cells of the cellular structure. The nodes include minor nodes at which 2-4 joists are connected, and major nodes at which 6-8 joists are connected. The cells of the cellular structure comprise a first circumferential row of first-row cells. Each of the first-row cells is connected to each of its circumferentially-adjacent first-row cells at a respective one of the major nodes, and is longitudinally delimited by two of the minor nodes. Other embodiments are described.
