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.
