1. A medical device, comprising
a plurality of prongs, each of the prongs having a sensor configured to detect a flow of fluid, and wherein each of the prongs includes an indicator that communicates whether the respective sensor detects the flow of fluid; and
a sleeve disposed radially outward of the plurality of prongs;
wherein the sleeve is configured to move proximally and distally relative to the plurality of prongs to transition the plurality of prongs from a contracted configuration to an expanded configuration.
