Abstract
A syringe configured to deliver viscous compositions is described, in which the syringe may include an elongate chamber having side port(s) extending therefrom. Various viscous compositions may be inserted through the side port(s) and into the elongate chamber, which may further house a plunger for ejecting the composition. One portion of the plunger may interact with a restricted opening on the chamber to inhibit removal of the plunger from the chamber; and another portion of the plunger may have a locking structure, which cooperates with a locking structure on the chamber to selectively fix the plunger with respect to the chamber. The plunger may also be fully slidable within the chamber when the locking structures of the plunger and the elongate chamber are not engaged. Related methods of using the aforementioned syringe, as well as kits including further instruments that interact with the syringe, are also disclosed.
