Abstract
A fluid delivery device for delivery and mixing of fibrin glue components at a treatment site during surgery includes a slidable sleeve for controlling interaction of fluid dispensed from a pair of adjacent tubes. A pair of syringes are attached to a fluid separation control attachment which allows the fluids from each of the syringes to be forced into the adjacent tubes. When the fluids exit the free ends of the adjacent tubes, they interact and mix when the slidable sleeve thereon is in one position, but are inhibited from interacting and mixing when the slidable sleeve is in another position.
