A device and method for dispensing a liquid with a gas includes an instrument having a cannula and a low-pressure tip. The low-pressure tip includes a tip housing that at least partially defines a high pressure chamber. A distal wall of the tip housing includes an aperture in fluid communication with the high pressure chamber. The low-pressure tip also includes a tube and a gas flow channel. The tube fluidly communicates liquid at a relatively low pressure from the cannula through the first aperture. The gas flow channel fluidly communicates gas from the cannula at a relatively high pressure and to the high pressure chamber for discharge from the aperture. The tube and aperture are adapted to dispense the liquid and the gas in order to create a low pressure zone distal of the tube to dispense droplets of the liquid.

Device and method for discharging a reactive liquid

An apparatus and method for hydrating a particulate biomaterial with a liquid biomaterial includes a vacuum device and a valve for withdrawing a gas from the particulate biomaterial and introducing the liquid biomaterial. The valve includes a hub, a valve body, a particulate port, a vacuum port, and a liquid port. The valve body selectively moves between first and second positions. The valve body at least partially defines a first passage and a second passage. The particulate port, the vacuum port, and the liquid port are each configured to fluidly connect to a particulate container, the vacuum device, and the liquid container, respectively. In the first position, the first passage fluidly connects the vacuum port to the particulate port for withdrawing the gas from the particulate container. In the second position, the second passage fluidly connects the liquid port to the particulate port for hydrating the particulate biomaterial.

A device and method for improving hydration of a biomaterial includes a syringe having a cavity therein and a distal opening, an end cap, and a wall operatively coupled to the end cap. The end cap has a distal plate with an inlet and is removably attached to the syringe to cover the distal opening. The wall is positioned proximate to the inlet and at least partially defines a volume in fluid communication with the inlet. An orifice extends through the wall and fluidly connects the volume to the cavity. A flow of a liquid component of biomaterial diffuses through the orifice and is introduced into a particulate component of biomaterial. As such, the liquid component of biomaterial hydrates the particulate component of biomaterial.
