US Patent 10060217 Lattice seal packer assembly and other downhole tools

A downhole tool includes an elongated base pipe and a expandable element disposed on the base pipe and radially expandable from a first configuration to a second configuration. The expandable element includes a first lattice structure that includes a first plurality of connecting members; a second plurality of connecting members movable relative to the first plurality of connecting members to allow the expandable element to radially expand from the first configuration to the second configuration; and a plurality of cells, each of the cells being defined between at least two connecting members. Each of the connecting members from the at least two connecting members is from the first plurality of connecting members or from the second plurality of connecting members. In one or more exemplary embodiments, the first lattice structure is at least partially manufactured using an additive manufacturing process.
