A plunger for use with a dispensing syringe to dispense a biomaterial is disclosed. The plunger includes a plunger body having a plunger head at its distal end and a plunger base at its proximal end. The plunger body defines a plunger passageway extending through the plunger body from the proximal end to the distal end. The plunger head is received within a syringe passageway of the dispensing syringe, and the plunger passageway receives a stylet.

Assembly for dispensing biomaterial, plunger therefor, and related methods

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.

Medical material mixer and transfer apparatus and method for using the same

An assembly includes a dispensing syringe device configured to receive an amount of biomaterial and to dispense the biomaterial. The dispensing syringe device includes a syringe barrel for receiving the biomaterial, a discharge outlet for dispensing the biomaterial from the syringe barrel, and a plunger received in the syringe barrel. The plunger has a plunger body and a plunger passageway extending therethrough configured to receive a stylet. The assembly further includes a cannulus device configured to be coupled with the dispensing syringe device, to receive biomaterial from the dispensing syringe device, and to dispense the biomaterial. The cannulus device includes a cannulus passageway configured to receive the biomaterial and a dispensing opening configured for dispensing the biomaterial.

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.
