Abstract

A method and a device for moistening a porous medical material (50) utilize evacuation of the material before moistening it with a liquid which is contained in a container (48) for communication with the material (50).

Claims

1. A device for moistening an essentially non-biological medical implant material, said device comprising a first evacuated chamber (14;

54) containing the material and a second chamber (22;

48) containing a liquid.

2. The device according to claim 1, wherein both chambers can be connected for liquid transfer from one chamber into the other chamber.

3. The device according to one of the claim 1, comprising a septum (18) for injecting a liquid.

4. The device according to claim 1, wherein the liquid comprises a medicament.

5. A The device according to claim 1, wherein the material is a raw material comprising a binding phase of one or more powdered binding agents which, after moistening with a liquid reacting with the binding agents, forms first a formable material and then a chemically bonded ceramic material.

6. The device according to claim 5, wherein said raw material, before moistening it with the liquid, has a degree of compactness of 55-67 percent by volume solid phase.

7. The device according to claim 5, wherein said raw material, before it is moistened with a liquid, is in a compact form.

13. The device according to claim 2, comprising a septum (18) for injecting a liquid.

14. The device according to claim 7 wherein said compact form is a pill.

15. The device according to claim 7 wherein said compact form is a tablet.

8. The device for moistening an essentially non-biological medical implant material, said device comprising a chamber (14;

54) containing the material, characterized in that an evacuated cavity is provided which is connectable to said chamber containing the material such that, after moistening the porous material, excessive liquid is sucked away from the material into said cavity.

9. A method of moistening an essentially non-biological medical implant material, said method comprising the step of the evacuating said material before moistening it, wherein said material is a raw material comprising a binding phase of one or more binding agents which, after moistening with a liquid reacting with the binding agents, forms first a formable material and then a chemically bonded ceramic material.

10. The method according to claim 9, wherein said raw material comprises one or more powdered binding agents.

11. The method according to claim 9, wherein said raw material, before it is moistened with a liquid, is in a compact form.

12. The method according to claim 9, characterized in that said raw material, before moistening it with the liquid, has a degree of compactness of 55-67 percent by volume solid phase.

16. The method according to claim 11 wherein said compact form is a pill.

17. The method according to claim 11 wherein said compact form is a tablet.
