1. A system for deliverng bone cement through a delivery cannula, the system comprising:
a cement reservoir;
a flow diverter in fluid communication with the cement reservoir and comprising a valve defining a first diverter outlet and a second diverter outlet;
a cannula coupler coupled to first diverter outlet of the flow diverter and configured to be coupled to the delivery cannula for directing the bone cement from the cement reservoir to the delivery cannula;
a drool accumulator coupled to the second diverter outlet of the flow diverter and defining a drool volume for receiving the bone cement;
a cement delivery input mechanism coupled to the cement reservoir and configured to be actuated to direct the bone cement from the cement reservoir towards the flow diverter; and
a user input mechanism coupled to the flow diverter and configured to receive a user input to actuate the valve and establish the fluid communication selectively betveeri the cement reservoir and either the cannula coupler or the drool accumulator.
