First Claim
1. A syringe system comprising:
- a syringe body comprising a hollow lumen, a proximal open end, and a distal end, the syringe body being configured to house a fluid therein; and
a plunger positioned in the hollow lumen of the syringe body, forming a seal with an inner wall of the syringe body, the plunger comprising;
a removable piston having a shaft extending from the distal end towards the proximal open end,a stopper removably connected to a distal portion of the shaft, the stopper configured to slidably move within the hollow lumen to facilitate movement of the fluid within the syringe body, andat least one coupler at the distal portion of the shaft, wherein the coupler is configured to facilitate removal and attachment of the stopper from the piston.

Abstract
A syringe system and components thereof are disclosed. The system may include a syringe body having a hollow lumen, a proximal open end, and a distal end. The syringe body may be configured to house a fluid therein. The syringe system may further include a plunger positioned in the hollow lumen of the syringe body, forming a seal with an inner wall of the syringe body. The plunger may include a removable piston having a shaft extending from the distal end towards the proximal open end, a stopper removably connected to a distal portion of the shaft, and at least one coupler attached to the distal portion of the shaft. The stopper may be configured to slidably move within the hollow lumen to facilitate movement of the fluid within the syringe body. The coupler may be configured to facilitate removal and attachment of the stopper from the piston.

24. A hydraulically-activated plunger in a fluid delivery system, the plunger comprising:
-
a first syringe comprising a first diameter, a proximal end, a distal end having an aperture, and a hollow lumen configured to house a fluid therein; a stopper configured to slidably move within the hollow lumen to facilitate movement of the fluid within the hollow lumen; an internal piston having a distal end and a proximal end, wherein the distal end is removably attached to the stopper and configured to move the stopper within the hollow lumen of the first syringe, and wherein the proximal end is fluidly attached to a second syringe having a proximally positioned tip and a second diameter that is smaller than the first diameter; a third syringe having a distally positioned tip and a third diameter that is smaller than the first diameter, wherein the distally positioned tip of the third syringe is in fluid communication with the proximally positioned tip of the second syringe; and an external piston fluidly connected to the third syringe, wherein the external piston comprises a plunger, wherein the second syringe and the third syringe each contain an incompressible fluid sealed therein.
