1. A method comprising:
implant a stent graft and a wire within a patient and adjacent one another;
advance a first conduit over the wire and into the patient;
insert a second conduit into the first conduit, wherein within the second conduit: (a) first, second, and third open-cell, polyurethane, thermoset, shape memory polymer (SMP) foams are simultaneously disposed; and (b) the first, second, and third SMP foams are arranged serially with respect to each other and are not fixedly coupled to each other;
deploy the first SMP foam from the first conduit and into the patient at a first location;
after deploying the first SMP foam, deploy the second SMP foam from the first conduit and into the patient at a second location; and
after deploying the second SMP foam, deploy the third SMP foam from the first conduit and into the patient at a third location;
wherein (a)(i) a first plane, orthogonal to a long axis of the first SMP foam, intersects both a proximal half of the first SMP foam and a first metal structure that is coupled to the first SMP foam; (a)(ii) an additional first plane, parallel to the first plane, intersects a distal half of the first SMP foam but does not intersect the first metal structure, (b)(i) a second plane, orthogonal to a long axis of the second SMP foam, intersects both a proximal half of the second SMP foam and a second metal structure that is coupled to the second SMP foam; (b)(ii) an additional second plane, parallel to the second plane, intersects a distal half of the second SMP foam but does not intersect the second metal structure, (c)(i) a third plane, orthogonal to a long axis of the third SMP foam, intersects both a proximal half of the third SMP foam and a third metal structure that is coupled to the third SMP foam; (c)(ii) an additional third plane, parallel to the third plane, intersects a distal half of the third SMP foam but does not intersect the third metal structure.
