Abstract

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.

First claim

What is claimed is:

1. A method of hydrating a particulate biomaterial held within a particulate container with a liquid biomaterial held within a liquid container to form a mixture of biomaterials, the method using a vacuum device and a valve, the valve being fluidly connected to the particulate container, the liquid container, and the vacuum device, the valve having a valve body configured to selectively move between a first position and a second position, and having a check valve provided within the valve body, the method comprising:
generating a vacuum within the particulate container with the vacuum device when the valve body is in the first position;
withdrawing a gas from the particulate container and through the valve body and the check valve toward the vacuum device to maintain the vacuum within the particulate container;
moving the valve body to the second position such that the liquid container fluidly connects to the particulate container via the valve body;
releasing the vacuum within the particulate container to the liquid container to withdraw the liquid biomaterial from the liquid container and introduce the liquid biomaterial into the particulate container; and
hydrating the particulate biomaterial with the liquid biomaterial to form the mixture of biomaterials.

2. The method of claim 1 , wherein hydrating the particulate biomaterial further comprises forcing the mixture of biomaterials from the particulate container, through the valve body, and to the liquid container to blend the mixture of biomaterials.

3. The method of claim 1 , further comprising connecting the vacuum device to the valve while simultaneously directing the valve body toward the first position.

4. The method of claim 1 , further comprising disconnecting the vacuum device from the valve while simultaneously directing the valve body toward the second position.

5. The method of claim 1 , wherein the particulate biomaterial and the liquid biomaterial comprise bone graft materials.

6. The method of claim 5 , further comprising dispensing the mixture of the bone graft materials onto an anatomical site during a medical procedure.

7. The method of claim 1 , wherein moving the valve body to the second position comprising rotating the valve body to the second position.

8. The method of claim 7 , wherein:
the valve body defines a vacuum port, and
comprising rotating the valve body to the second position comprises disconnecting the vacuum port from the vacuum device.

9. The method of claim 1 , wherein moving the valve body to the second position comprises linearly translating the valve body to the second position.

10. The method of claim 1 , wherein:
the vacuum device is a first syringe comprising a first syringe body and a first piston, and
generating the vacuum within the particulate container with the vacuum device comprises withdrawing the first piston within the first syringe body.

11. The method of claim 10 , wherein the particulate container is a second syringe configured to hold the particulate biomaterial.

12. The method of claim 11 , wherein the liquid container is a third syringe configured to hold the liquid biomaterial.

13. The method of claim 1 , wherein:
the valve further comprises a hub, and
the method further comprises movably coupling the valve body to the hub to selectively move between the valve body between the first position and the second position.

14. The method of claim 1 , wherein the check valve is a first check valve, and the valve further comprises a second check valve in fluid communication with a passage of the vacuum device and an ambient environment.

15. A method of hydrating a particulate biomaterial held within a particulate container with a liquid biomaterial held within a liquid container to form a mixture of biomaterials, the method using a vacuum device and a valve, the valve being fluidly connected to the particulate container, the liquid container, and the vacuum device, the valve having a valve body configured to selectively move between a first position and a second position, and having a first check valve and a second check valve, the second check valve in fluid communication with a passage of the vacuum device and an ambient environment, the method comprising:
generating a vacuum within the particulate container with the vacuum device when the valve body is in the first position;
withdrawing a gas from the particulate container and through the valve body and the first check valve toward the vacuum device to maintain the vacuum within the particulate container;
discharging the gas from the passage and through the second check valve into the ambient environment when the valve body is in the first position;
moving the valve body to the second position such that the liquid container fluidly connects to the particulate container via the valve body;
releasing the vacuum within the particulate container to the liquid container to withdraw the liquid biomaterial from the liquid container and introduce the liquid biomaterial into the particulate container; and
hydrating the particulate biomaterial with the liquid biomaterial to form the mixture of biomaterials.

16. The method of claim 15 , wherein hydrating the particulate biomaterial further comprises forcing the mixture of biomaterials from the particulate container, through the valve body, and to the liquid container to blend the mixture of biomaterials.

17. The method of claim 15 , wherein moving the valve body to the second position comprises rotating the valve body to the second position.

18. The method of claim 17 , wherein:
the valve body defines a vacuum port, and
rotating the valve body to the second position comprises disconnecting the vacuum port from the vacuum device.

19. The method of claim 15 , wherein moving the valve body to the second position comprises linearly translating the valve body to the second position.

20. The method of claim 15 , wherein:
the valve further comprises a hub, and
the method further comprises movably coupling the valve body to the hub to selectively move between the valve body between the first position and the second position.
