A delivery assembly includes a console including a vial containment region and a vial engagement mechanism extending from the console within the vial containment region. The engagement mechanism is configured to engage a vial assembly including a particulate material. The delivery assembly further includes a multi-port needle with a top distal port and bottom proximal port(s), the needle configured to puncture a septum of the vial assembly when the vial assembly is in the locked position, in which the top distal port is at a distance above the particulate material in the vial assembly. The ports are configured to inject a fluid into the vial assembly to mix with the particulate material upon actuation of the vial engagement mechanism in a first direction and to receive a resulting mixed fluid from the vial assembly upon actuation of the vial engagement mechanism in a second opposite direction.

Embodiments of a syringe-based device for procuring bodily fluid samples can include a housing having a port that can be coupled to a lumen-defining device for receiving bodily fluids, an actuator mechanism retained at least partially within the housing, the actuator mechanism including a pre-sample reservoir, a plunger operably coupled with pre-sample reservoir, a plunger cap, a plunger tube, a valve, a plunger seal, an a selectively attachable collection vial for capturing a bodily fluid sample.

The present disclosure relates to a syringe including a container, for containing a primary fluid, and at least one secondary fluid chamber configured to contain a secondary fluid. The container comprises a proximal end and a distal end and having a distal end opening at the distal end. The syringe further comprises a stopper, movably arranged within the container; and a plunger engageable with the stopper and configured to apply a force to the stopper to move the stopper within the container towards the distal end of the container, to expel primary fluid from the container through the distal end opening. The plunger is further configured to expel secondary fluid from the at least one secondary fluid chamber towards the distal end opening, to expel at least a portion of a residual volume of primary fluid through the distal end opening. A plunger system and assembly for a syringe and methods of expelling fluid from a syringe are also disclosed.

A syringe-based apparatus includes a housing having an open proximal end and a distal end, a needle coupled with the distal end of the housing, an actuator mechanism coupled with the housing, the actuator mechanism including a syringe body and a plunger, the syringe body and the plunger being insertable into the open proximal end of the housing. A medicament reservoir is defined at least partially by the housing and the actuator mechanism, and a reconstitution fluid reservoir is defined at least partially by the syringe body and the plunger of the actuator mechanism. The plunger is operably configured to move relative to the syringe body to expel the amount of the fluid from the reconstitution fluid reservoir into the medicament reservoir. The actuator mechanism is operably configured to move relative to the housing to expel the amount of the fluid from the medicament reservoir through the needle.

Introduced here are novel techniques for augmenting the lips through superficial linear injection of dermal fillers. At a high level, these techniques are representative of a two-step approach to augmentation. In the first stage, an implement that is appropriately positioned inside a lip can be moved sideways—an action referred to as a “side push.” In the second stage, dermal filler can be ejected from the implement so as to fill the resulting void. These techniques can be used by healthcare professionals to reshape the lips for medical or aesthetic purposes. These techniques were developed in an attempt to permit augmentation of the outer surface of a lip so as to increase its volume by expanding sideways while turning the lip outward. With these techniques, the desired result—namely, a plumper lip—may be readily and consistently achievable.

Embodiments include a syringe-based apparatus for delivering fluid, the apparatus comprising a housing having an open proximal end and a distal end defining an inner volume, a needle, an actuator mechanism coupled with the housing, the actuator mechanism comprising a syringe body and a plunger, a medicament reservoir, and a reconstitution fluid reservoir.

Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.

A syringe pump determines, upon receiving a new syringe, that at least a first portion of a predetermined amount of a first fluid was previously delivered by the syringe pump according to a first fluid delivery order before the new syringe was loaded into the syringe pump, and determines a second portion of the first fluid remaining to be delivered to complete the predetermined amount of the first fluid for the first fluid delivery order. A delivery of a second fluid is initiated by the syringe pump and, when an amount of the second fluid delivered from the new syringe satisfies the second portion of the first fluid remaining to be delivered, the pump automatically, without user intervention, indicates the first fluid delivery order as being complete, de-associates the first fluid delivery order from the syringe pump, and associates the syringe pump with the second fluid delivery order.

Devices and methods are disclosed that provide a syringe actuator device for use in the distention and irrigation of a body conduit before the use in a medical procedure such as a coronary bypass graft procedure. The device can be retrofit to a syringe by attaching it to the cap of the plunger and engaged to automatically apply pressure to fluid in the syringe. In some embodiments, elastic bands attached to the device are easily engaged or removed from a syringe during a procedure to limit the pressure on the syringe to various levels. The device may be overridden by an operator pushing on the plunger of the syringe as in normal syringe operation.

Provided is an apparatus, system, and method for a nested syringe assembly. The nested syringe assembly includes a first syringe having a cylindrical body defining an inner diameter and a second syringe having a cylindrical body defining an outer diameter. The outer diameter of the second syringe is less than the inner diameter of the first syringe. At least a portion of the cylindrical body of the second syringe is disposed within the cylindrical body of the first syringe.
