Abstract

Devices for hydrating materials, such as, for example, medical implant materials include a container body defining therein a hydration chamber. A barrier separates the chamber into a material holding area and a hydrating fluid bay and defines at least one aperture and is configured to allow passage of hydrating fluid from the hydrating fluid bay to the material holding area. In some embodiments, devices provided by the present application are operable for use in hydrating and delivering a material.

Claims

1. A device for hydrating a medical implant material, comprising:

a container body defining therein a hydration chamber; and

a barrier extending from one side of the hydration chamber to an opposing side and separating the hydration chamber into a material holding area and a hydrating fluid bay,

the barrier being porous and defining a plurality of capillary apertures through which the material holding area fluidly communicates with the hydrating fluid bay such that a hydrating fluid moves to the material holding area only by flowing through the plurality of capillary apertures,

wherein said plurality of capillary apertures allow passage of the hydrating fluid from the hydrating fluid bay to the material holding area,

wherein the device further comprises a removable seal effective to prevent passage of the hydrating fluid from the hydrating fluid bay to the material holding area, the removable seal extending from the one side of the hydration chamber to the opposing side adjacent to the barrier, the removable seal connected to a tab external to the container body, and the removable seal and the tab configured to be pulled entirely free from the device to allow for passage of the hydrating fluid to the material holding area,

wherein the container body is composed of a rigid material, wherein the container body comprises first and second portions configured for alternate engagement with one another to form the hydration chamber, and disengagement from one another for removal of a material from the material holding area,

the first and second portions being connected to one another by a hinge and a fastener,

wherein the first and second portions are separable from one another.

2. The device in accordance with claim 1, wherein the barrier comprises a member selected from the group consisting of a permeable element, a screen and a fabric.

3. The device in accordance with claim 1, further comprising a connection port in fluid communication with the hydrating fluid bay, the port configured for engagement with a hydrating fluid source.

4. The device in accordance with claim 3, further comprising a valve in fluid communication with the material holding area.

5. The device of claim 3, further comprising a pressure applicator attachable to the port.

6. The device of claim 5, wherein the pressure applicator comprises a hydraulically-actuated piston or a hydraulically-inflatable bladder.

7. The device of claim 3, wherein the port is connected to a threaded fitting and a valve.

8. The device in accordance with claim 1, further comprising a gasket between the first and second portions to provide a seal when the first and second portions are in an engaged position.

9. The device in accordance with claim 1, further comprising a material to be hydrated contained in the material holding area;

wherein the material to be hydrated is further contained in a delivery device.

10. The device of claim 1, wherein the rigid material is a plastic material.
