Syringe for the delivery of viscous compositions
First Claim
1. A device for the delivery of a composition, the device comprising:
- (a) an elongate chamber having a lumen;
(b) a cap on the proximal end of the chamber having a restricted opening, the cap covering at least a portion of the lumen of the chamber;
(c) at least one side port having a lumen, said side port lumen being in fluid communication with the lumen of the elongate chamber; and
(d) a plunger having a plunger seal slidable in sealing engagement within the lumen of the elongate chamber from a position proximal to conjunction of the lumens of the side port and elongate chamber to a position distal to said conjunction;
(e) the plunger having an interference member that inhibits removal of the plunger from the elongate chamber through the restricted opening; and
(f) the elongate chamber having a locking structure that is engageable and disengageable with a corresponding locking structure on the plunger, wherein engagement between the locking structures of the elongate chamber and the plunger locks the plunger and its plunger seal relative to the elongate chamber, and disengagement between the locking structures of the elongate chamber and the plunger unlocks the plunger and its plunger seal relative to the elongate chamber so that the plunger and its plunger seal are movable within the elongate chamber.

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.

21. A device for the delivery of a composition, the device comprising:
-
(a) an elongate chamber having a lumen; (b) a cap on the proximal end of the chamber having a restricted opening, the cap covering at least a portion of the lumen of the chamber; (c) at least one side port having a lumen, said side port lumen being in fluid communication with the lumen of the elongate chamber; (d) a plunger having a plunger seal slidable in sealing engagement within the lumen of the elongate chamber from a position proximal to conjunction of the lumens of the side port and elongate chamber to a position distal to said conjunction; (e) a locking structure on the elongate chamber that is engageable and disengageable with a corresponding locking structure on the plunger, wherein engagement between the locking structures of the elongate chamber and the plunger locks the plunger and its plunger seal relative to the elongate chamber in a locked position, and disengagement between the locking structures of the elongate chamber and the plunger unlocks the plunger and its plunger seal relative to the elongate chamber so that the plunger and its plunger seal are movable within the elongate chamber; and (f) a rotational element on the plunger which, when the plunger is in the locked position, indicates to a user of the device that the plunger is in the locked position; (g) the plunger having an interference member that cooperates with the restricted opening to inhibit removal of the plunger from the elongate chamber through the restricted opening. - View Dependent Claims (22, 23, 24)
