1. A reconfigurable medical device comprising:
a central core; and
a plurality of arms rotatably coupled to the central core such that the plurality of arms are configured to rotate outwards away from the central core to selectively reconfigure the reconfigurable device between a first retracted configuration and a second expanded configuration, wherein in an initial state each arm of the plurality of arms is biased outwards away from the central core into the second expanded configuration, wherein when the reconfigurable device is exposed to a temperature greater than a threshold temperature, each arm of the plurality of arms is biased towards the central core into the first retracted configuration, and wherein, in the first retracted configuration, a longitudinal axis of each arm of the plurality of arms is parallel to a longitudinal axis of the central core and, in the second expanded configuration, the longitudinal axis of each arm of the plurality of arms is perpendicular to the longitudinal axis of the central core.
