Abstract

A method of mixing and delivering a substance to a bone includes providing a compressible tube having a reservoir and using a mixing apparatus to mix a particulate solid and a mixing liquid to form the substance within the reservoir of the compressible tube. The method further includes using a compressing device to move the substance through an exit port in the compressible tube for delivery to the bone. The compressing device may be positioned on the compressible tube and the method may further include moving the compressing device along the compressible tube to empty the substance from the compressible tube. The substance may be a bone void filler, and the substance may be delivered from the exit port in the tube through a delivery apparatus, such as a cannula, to a target portion of the anatomy.

First claim

What is claimed is:

1. A method of mixing and delivering a substance to a bone, comprising:
providing a compressible tube having a reservoir and an exit portal, the compressible tube containing at least a first substance element therein;
introducing a second substance element to the first substance element;
introducing a mixing apparatus into the reservoir through the exit portal;
mixing the first substance element and the second substance element using the mixing apparatus to form the substance within the reservoir of the compressible tube;
removing the entirety of the mixing apparatus from the reservoir; and
delivering the substance through the exit portal in the compressible tube for delivery to the bone using a compressing device.

2. The method of claim 1 , wherein the first substance element is a particulate solid and the second substance element is a mixing liquid.

3. The method of claim 1 , further comprising introducing the second element into the reservoir of the compressible tube.

4. The method of claim 1 , further comprising moving the substance through the exit portal and into a delivery apparatus for delivery directly to the bone.

5. The method of claim 4 , wherein the delivery apparatus is a cannula positioned within the body and having a distal portion position near a target portion of the bone.

6. The method of claim 1 , wherein the substance is a bone void filler.

7. The method of claim 1 , wherein the compressing device is positioned on the compressible tube and wherein the method further comprises moving the compressing device along the compressible tube to empty the substance from the compressible tube.

8. The method of claim 7 , wherein the compressing device comprises a rolling key to roll the compressible tube to empty the substance from the compressible tube.

9. The method of claim 1 , wherein the second element is introduced to the reservoir through a sealable inlet portion.

10. The method of claim 9 , wherein the compressible tube further comprises a portal comprising the sealable inlet portion and the exit portal.

11. The method of claim 1 , wherein the first element is selected from the group consisting of stem cells and a bone marrow aspirate.

12. The method of claim 1 , wherein the first element is a paste material and the second material is a mixing liquid.
