1. A blood vessel access closure device, comprising:
an inner blood vessel wall support member configured to be positioned inside a blood vessel;
an outer blood vessel wall support member configured to be positioned outside the blood vessel;
a deployment member configured to draw the inner and outer blood vessel wall support members towards each other when the inner and outer blood vessel wall members are deployed on opposite sides of a blood vessel wall during closure of a hole in the blood vessel wall;
a first electrode configured to be attached to the deployment member, the first electrode being bioabsorbable;
multiple visual indicators; and
a circuit coupled to the first electrode and the multiple indicators, the circuit configured to determine a value indicative of impedance using the first electrode, determine that a bleed is occurring based on the value indicative of impedance, and cause the multiple visual indicators to indicate a severity of the bleed.
