1. A device for performing a surgical procedure, the device comprising:
- a plurality of outputs;
a pressure reservoir configured for selective coupling to one of the plurality of outputs;
a pressure source for pressurizing the pressure reservoir;
a diverter for coupling the pressure reservoir to one of the plurality of outputs, the diverter is configured for rotational movement between the one of a plurality of outputs;
a triggering feature disposed on the diverter and including a raised element configured for opening the pressure release valve when the diverter switches between the plurality of outputs,a pressure release valve for venting the pressure reservoir to a baseline pressure; and
wherein when the diverter is configured to switch between a first one of the plurality of outputs to a second one of the plurality of outputs, the triggering feature is configured to open the pressure release valve and cause the diverter to decouple the pressure reservoir from the first one of the plurality of outputs, and the triggering feature closes the pressure release valve after coupling the pressure reservoir with the second one of the plurality of outputs.

Abstract
A device for delivering material to multiple surgical target locations includes a pressure reservoir selectably coupled to two or more outlets. Coupling the pressure reservoir to a given one of the outlets and pressurizing the pressure reservoir causes flowable material (e.g., bone filler material) to be dispensed from that outlet. A diverter for selectably coupling the pressure reservoir one of the outlets can be configured to trigger a pressure release valve for the pressure reservoir upon switching, thereby preventing unexpected or uncontrolled material delivery from the new outlet in response to sudden high pressure exposure.

19. A device for performing a surgical procedure, the device comprising:
-
a plurality of outputs; a pressure reservoir; a pressure source for pressurizing the pressure reservoir; a diverter configured to define a flow path between the pressure reservoir and the plurality of outputs such that the diverter simultaneously couples the pressure reservoir the plurality of outputs such that material can be dispensed into a surgical site from at least two of the plurality of outputs simultaneously, the diverter is configured for rotational movement between the one of a plurality of outputs; and a triggering feature disposed on the diverter and including a raised element configured for opening a pressure release valve when the diverter switches between the plurality of outputs.
