A cannula assembly is removably mountable to a syringe body having a pair of side-by-side chambers; there being an opening into each chamber at a bottom of the syringe. The cannula assembly includes a connector and a dual lumen assembly extending from the connector. The dual lumen assembly includes a pair of tubes defining two fluid paths. The connector includes fluid paths which, when the cannula assembly is mounted to the syringe, place the fluid path of one of the tubes in fluid communication with one of the syringe body chambers and the fluid path of the other of the dual lumen tubes in fluid communication with the other of the syringe body chambers.
