Abstract
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.
Claims27
A device for improving hydration of a particulate component of biomaterial with a liquid component of biomaterial, the device comprising:
- a syringe having a syringe body and a cavity therein for containing the particulate component, the syringe body including a distal opening;
- a distal plate removably connected to the syringe body and at least partially covering the distal opening, the distal plate having an inlet extending therethrough for receiving the liquid component;
- a wall connected to the distal plate and positioned within the cavity, the wall at least partially defining a volume in fluid communication with the inlet, and the wall being configured to maintain the volume between the inlet and the particulate component within the cavity of the syringe;
- and
- at least one orifice extending through the wall and fluidly connecting the volume to the cavity such that the liquid component received by the inlet flows throughout the volume and into the cavity via the at least one orifice for diffusion of the liquid component and hydration of the particulate component within the cavity of the syringe,
- wherein a cross-sectional area of the at least one orifice is less than a cross-sectional area of the inlet.
A diffuser for improving hydration of a particulate component of biomaterial with a liquid component of biomaterial, the particulate component contained within a cavity of a syringe, the diffuser comprising:
- a distal plate configured for removable attachment to the syringe, the distal plate having an inlet extending therethrough for receiving the liquid component;
- a wall connected to the distal plate and configured to be positioned within the cavity, the wall at least partially defining a volume in fluid communication with the inlet, and the wall being configured to maintain the volume between the inlet and the particulate component within the cavity of the syringe;
- and
- at least one orifice extending through the wall and configured to be in fluid communication with the volume such that the liquid component received by the inlet is configured to flow throughout the volume and through the orifice for diffusion of the liquid component and hydration of the particulate component within the cavity of the syringe,
- wherein a cross-sectional area of the at least one orifice is less than a cross-sectional area of the inlet.
A method of improving hydration of a particulate component of biomaterial with a liquid component of biomaterial, the particulate component contained within a syringe and positioned against a wall having at least one orifice extending therethrough, the wall being connected to a distal plate having an inlet, the distal plate being removably connected to the syringe, the method comprising:
- diffusing a flow of the liquid component through the inlet of the distal plate and the at least one orifice in the wall in order to form at least one diffused flow of liquid component;
- introducing the diffused flow of the liquid component into the particulate component within the syringe;
- and
- distributing the liquid component throughout the particulate component in order to hydrate the particulate component with the liquid component.
