Claim 13:
14. A system comprising:
an outer conduit having proximal and distal ends;
a shape memory polymer (SMP) foam having proximal and distal ends and that is configured to transition from a SMP foam secondary shape to a SMP foam primary shape when the SMP foam is heated above its transition temperature;
a metal backbone including: (a)(i) a first portion that extends from the SMP foam proximal end to the SMP foam distal end and which is generally covered by the SMP foam, and (a)(ii) a second portion that extends distally from the SMP foam distal end and which is not covered by the SMP foam;
wherein: (b)(i) the SMP foam and the metal backbone are both included within the outer conduit; (b)(ii) the metal backbone second portion is configured to transition from a metal backbone second portion secondary shape to a metal backbone second portion primary shape; (b)(iii) the metal backbone second portion is in the metal backbone second portion secondary shape and is located between the SMP foam distal end and the distal end of the outer conduit; (b)(iv) the metal backbone second portion includes an outer metal portion including a channel; (b)(v) the metal backbone second portion primary shape has a circular base between the SMP foam and a distal tip of the metal backbone; and (b)(vi) at least a portion of the SMP foam is slidingly coupled to the metal backbone.
