Abstract:
Embodiments of a syringe-based device for delivering fluid include a housing, a port, the port being positioned at about the distal end of the housing, a plunger assembly, the plunger assembly including, a plunger seal, a valve, and a cannula, a first fluid reservoir, where the first fluid reservoir retains a first type of fluid, a syringe including a syringe body, a syringe port, a plunger, and a second fluid reservoir, the second fluid retaining a second type of fluid, and where the syringe transitions from a first configuration in which a first portion of the first fluid type is delivered through the port, to a second configuration in which the second type of fluid in the second fluid reservoir is delivered through the port, to a third configuration in which a second portion of the first fluid type is delivered through the port.

Claim (Index 1):
A syringe-based method for delivering fluid, the method comprising the steps of:\n providing a housing, the housing having an open proximal end and a distal end defining an inner volume, the housing including;\n (a) a seal, the seal being sized to close the open proximal end of the housing such that the inner volume of the housing remains sterile until the seal is removed; \n (b) a port, the port being positioned at about the distal end of the housing, wherein the port is configured to be coupled to a lumen-defining device for delivery of fluid to a patient; \n (c) an abutment, the abutment being substantially disk-shaped and monolithically formed with the housing in a unitary, one-piece construction; \n (d) a cylinder, the cylinder extending distally from the abutment to the distal end of the housing, wherein the cylinder defines a lumen that is fluidically coupled with the port; \n (e) a first annular band; and \n (f) a second annular band; \n providing a plunger assembly, the plunger assembly having a proximal end and a distal end, the plunger assembly including;\n (a) a plunger seal, the plunger seal being positioned within the housing, proximal to the first annular band, wherein the plunger seal defines a channel; \n (b) a valve, the valve being a one-way check valve, wherein the valve is seated within at least a portion of the channel, and wherein the valve has a threaded proximal portion; and \n (c) a cannula, the cannula extending distally from the plunger seal, wherein the cannula is monolithically formed with the plunger seal in a unitary, one-piece construction; \n providing a first fluid reservoir, the first fluid reservoir being defined at least partially by the housing, the abutment, and the plunger seal, wherein the first fluid reservoir retains a first amount of a first type of fluid; providing an actuator mechanism including a proximal end portion and a distal end portion, the actuator mechanism configured to be retained at least partially within the inner volume defined by the housing after the seal is removed, wherein the actuator mechanism is movable relative to the housing, the actuator mechanism including;\n (a) syringe body having a proximal end and a distal end, the distal end of the syringe body having a syringe port, wherein the syringe port is fluidically coupleable to the threaded proximal portion of the valve; and \n (b) a plunger having a proximal end and a distal end, wherein the plunger is moveable within the syringe body from a proximal position to a distal position; and \n (c) providing a second fluid reservoir, the second fluid reservoir being defined at least partially by the syringe body and the plunger, wherein the second fluid reservoir is fluidically coupled with the syringe port and retains a second amount of a second type of fluid; and \n transitioning the actuator mechanism from a first configuration in which a first portion of the first amount in the first fluid reservoir is delivered through the port, to a second configuration in which the second amount of the second type of fluid in the second fluid reservoir is delivered through the port; and transitioning the actuator mechanism from the second configuration to a third configuration in which a second portion of the first amount in the first fluid reservoir is delivered through the port.
