Abstract
A threaded syringe provides a mechanism by which a clinician can deliver a viscous fluid through a relatively small lumen and can obtain tactile or audible feedback of delivery. The threaded syringe allows for delivery of more viscous fluids with less force and/or allows for more controlled delivery. The syringe includes a syringe barrel and a sliding member positioned on the proximal end of the syringe barrel. The sliding member has a first threaded hole and a second hole. The sliding member is slidable on the syringe barrel between a first position at which the first threaded hole is aligned with the syringe barrel for precise delivery of a material from the syringe and a second position at which the second hole is aligned with the syringe barrel for filling of the syringe or to stop bleed out.
