Abstract
A syringe delivery system for dispensing a highly viscous material through a syringe delivery opening includes a syringe barrel having a delivery opening, a plunger stem including a threaded shaft that threadably engages a proximal end of the syringe barrel for selectively dispensing a viscous material through the delivery opening, and a sheath. The sheath is rigidly attached with the plunger stem so that the plunger stem and sheath rotate together in unison relative to the syringe barrel. The sheath and syringe barrel may enclose the plunger stem. In order to dispense a viscous material, the syringe barrel is rotated relative to the sheath, causing the syringe barrel to be progressively received within the sheath and simultaneously forcing the plunger stem further into the syringe barrel so as to dispense a viscous material from the delivery opening.
