An apparatus and method for delivering a granular or powdered material, e.g., a bone growth promoting material. The inventive syringe apparatus includes a syringe barrel having a proximal and distal end, a lid attached to the syringe barrel that is selectively movable between an open and closed position relative to the syringe barrel, and biasing means for biasing the lid toward a closed position relative to the syringe barrel. The biasing means may comprise a leaf spring, coiled spring, or elastomeric material. The syringe barrel may be straight or curved.
