1. A catheter device, comprising:
a cannula capture mechanism comprising:
an outer housing;
an inner housing, wherein at least a portion of the inner housing is disposed within the outer housing, wherein the inner housing comprises a plurality of arms; and
a cannula that extends into the inner housing,
wherein when the cannula is retracted proximally within the inner housing, the outer housing is configured to move in a distal direction from a compressed state to a decompressed state and to bias the plurality of arms of the inner housing together to prevent the cannula from exiting a distal end of the inner housing.
