1. A system comprising:
a catheter;
an optic fiber having a long axis and a short axis that is orthogonal to the long axis;
a metal conduit fixedly coupled to the optic fiber;
a shape memory polymer (SMP) foam; and
a fluid to transfer thermal energy from the optic fiber to the SMP foam
wherein (a)(i) a plane orthogonal to the long axis intersects both the optic fiber and the metal conduit, (a)(ii) in a first configuration the metal conduit has a first maximum outer diameter measured orthogonal to the long axis and in a second configuration the metal conduit has a second maximum outer diameter measured orthogonal to the long axis, (a)(iii) the second maximum outer diameter is greater than the first maximum outer diameter but smaller than an inner diameter of the catheter, and (a)(iv) the metal conduit is, when in the second configuration, to center the optic fiber within the catheter and in the plane.
