Methods, apparatus and kits for preparing a medical mixture are disclosed. A method of preparing the medical mixture includes introducing a material into a tray, transferring the material from the tray to a scooper, releasably securing the scooper to the tray, and introducing a tubular member defining a lumen into the scooper such that the material within the scooper enters the lumen. A mixing apparatus includes a tray comprising a body defining a mixing receptacle configured to receive a material, a scooper having a proximal end with a proximal opening and a distal end with a distal opening, and a connector configured to releasably secure the scooper to the tray. A kit includes a tubular member, a stylet, a tray, and a scooper.

An applicator and method for dispensing a stream of a particulate and a fluid from a cannula and a mixing tip. The mixing tip includes a housing having an inlet, an outlet, and a mixing channel extending therebetween. A fin is positioned within the housing and extends along at least a portion of the mixing channel. The fin spirals about the mixing channel from the inlet toward the outlet for mixing and distributing the particulate generally uniformly within the fluid. The stream is directed into the mixing channel of the mixing tip and spiraled along the fin within the mixing channel. The spiraling increases turbulence and mixes the stream into a mixed stream of particulate and fluid. The mixed stream is discharged from the mixing tip for being dispensed onto an anatomical site.

A dispensing assembly includes a syringe body having a barrel and a dispensing tip. The dispensing assembly further includes a mixing and plunging assembly configured for coupling with the syringe body and comprising a mixer and a plunger. The mixer is configured for mixing material in the barrel and has a rod and a mixing element removably connected with the rod. The plunger is configured to dispense material from the barrel through the dispensing tip. Also, the rod is configured to be detached from the mixing element and used to push material out of the dispensing tip.

A device and method for removing gas from a mixture of biomaterials includes a vacuum pump movably positioned within a cavity of a syringe at least partially defining a vacuum chamber. The vacuum pump has a pump body with proximal and distal portions, a stopper connected to the distal portion, and a flow channel. The stopper includes an inlet, and the pump body includes a port. The flow channel extends from the inlet to the port and is in fluid communication with the vacuum chamber. A first valve is positioned within the flow channel between the inlet and the port. The first valve is operable to open and close the flow channel for selectively connecting a vacuum to the vacuum chamber such that gas is withdrawn from mixture of biomaterials within the vacuum chamber.

A gas-assisted fluid-dispensing device () for delivering an aerosol. The gas-assisted fluid-dispensing device () includes a syringe () that contains a fluid and includes a distal end (), a proximal end (), and a plunger () extending proximally from the proximal end (). A spray nozzle tip () is configured to generate the aerosol and is coupled to the distal end () of the syringe (). The gas-assisted fluid-dispensing device () further includes a housing () having first and second housing portions (). The first housing portion () includes a docking port () for receiving the syringe (); the second housing portion () is configured as a handle. A trigger (), coupled to the housing (), is operably coupled to an actuating member () that is configured to apply a force onto the plunger () of the syringe () and discharge the fluid from the syringe () and into the spray nozzle tip (). A self-contained pressurized gas source () is coupled to the housing () such that it moves with the housing () and is also coupled to the spray nozzle tip (). Delivery of a pressurized gas to the spray nozzle tip () is controlled by a control mechanism () and atomizes the fluid to generate the aerosol.

An apparatus for making and administering two non-homogenous liquids to target tissue includes a spray comprising two syringes for containing the first and second non-homogenous liquid where the syringes are adapted to be removably coupled to an applicator. The applicator includes a pair of elongated tubes each having a tubular sheath at a proximal end, a distal end and a lumen in which the pair of elongated tubes are disposed. The apparatus includes a regulator module having an inlet port adapted for connection to a source of gas under pressure and a gas outlet port adopted for connection to the gas inlet port of the sheet. A vent gas inlet port is adapted for connection to a vent port of an endoscopic cannula where the regulator vents a quantity of gas from the endoscopic cannula approximately equal to a quantity of gas introduced at the gas inlet port of the sheet.

An apparatus for equalizing pressure in a middle ear includes a hand-held air source for providing a continuous flow of air at a predetermined rate and a tapered sealing nostril plug adapted to be sealed against a nostril. The tapered nostril plug has a channel there through for delivering the continuous flow of air. The channel of the tapered plug is adapted to be placed in communication with the air source through an adjustable valve assembly for selecting a pressure limit for the air in the channel of the nostril plug.

A stent specifically designed for use in treating chronic sphenoid sinusitis comprises a soft compressible plastic tube of a predetermined diameter having a proximal end, a distal end and a lumen extending therebetween. The stent has a generally hemispherical hollow dome integrally molded to its distal end. The diameter of the dome is greater than the predetermined diameter of the plastic tube. The stent further includes an integrally molded annular flange located a short predetermined distance proximal to the hemispherical dome. The device is designed to be fitted through a surgically enlarged ostium of the sphenoid sinus such that the dome resides within the sinus cavity and the flange abuts the bony wall surrounding the ostium. The stent maintains the ostium patent and permits irrigation/suctioning via the stent's lumen.
