1. A system comprising:
a cage with proximal and distal strut portions, the proximal and distal strut portions each including a shape memory (SM) material; and
a contiguous single-piece shape memory polymer (SMP) foam including first and second foam portions;
wherein (a) the proximal strut portions are configured to expand to form a proximal cage portion and the distal strut portions are configured to expand to form a distal cage portion; and (b) the SMP foam is included in at least one of the proximal or distal cage portions; and
wherein the first foam portion is configured to slide (a) within the at least one of the proximal or distal cage portions, and (b) towards the second foam portion;
wherein the proximal and distal cage portions are joined together at a cage location that has a smaller maximum diameter than at least one of the proximal or distal cage portions.
