An embolectomy cage having an elongate axis and a circumference comprises a plurality of paired, closely spaced, substantially parallel, elongate members collectively defining a plurality of open cells, wherein individual elongate members of the pairs are connected at nodes located between respective pairs of axially adjacent cells and circumferentially adjacent cells, and wherein at least one elongate member spans each node without forming a connection to another elongate member. |

1. An embolectomy cage having an elongate axis and a circumference, comprising:
a plurality of paired, closely spaced, substantially parallel, elongate members arranged in a direction of the elongate axis and forming nodal and inter-nodal connections of the embolectomy cage along the elongate axis and about the circumference, wherein the pairs of elongate members collectively define a plurality of open cells, wherein an inner elongate member of a first pair of elongate members is connected to an inner elongate member of a second pair of elongate members at a first node located between a first pair of axially adjacent cells and a first pair of circumferentially adjacent cells, and wherein the inner elongate member of the first pair of elongate members is circumferentially spaced from the inner elongate member of the second pair of elongate members, wherein an outer elongate member of the first pair of elongate members and an outer elongate member of the second pair of elongate members each spans the first node without connection to another node, and wherein the outer elongate member of the second pair of elongate members forms a second node with an outer elongate member of a third pair of elongate members, the second node located between a second pair of axially adjacent cells and a second pair of circumferentially adjacent cells, wherein the inner elongate member of the first pair of elongate members is also connected to the inner elongate member of the second pair of elongate members at a third node that is axially spaced from the first node, wherein the second node is located between the first and third node along the elongate axis, wherein the inner and outer elongate members of the first pair of elongate members are connected to each other at a first inter-nodal interconnect located between the first node and the third node, and wherein the inner and outer elongate members of the second pair of elongate members are connected to each other at a second inter-nodal interconnect located between the first node and the second node. |
