A method for expressing two materials onto a selected site is disclosed. The method can include providing a syringe that is operable to maintain two separated materials substantially separate until a selected time. The method can further include mounting a tip portion to the syringe, the tip portion being operable to direct the two materials, either mixed or unmixed, to a selected site. The materials can include tissue sealants, growth factors, or other appropriate materials to be directed to a selected site.

A method of expressing a material to a selected site from an expressing assembly having a first chamber and a second chamber, wherein a first material in the first chamber is separated from a second material in the second chamber before expression of the first material and the second material fro
1. A method of expressing a material to a selected site from an expressing assembly having a first chamber and a second chamber, wherein a first material in the first chamber is separated from a second material in the second chamber before expression of the first material and the second material from the respective first chamber and second chamber, comprising: connecting a tip portion with the expressing assembly to form an extension of a first passage between a female connection portion of the expressing assembly or the tip portion and a male connection portion of the other of the expressing assembly or the tip portion;contacting a sealing member with the connected tip portion to seal the first chamber of the expressing assembly with the extension of the first passage;expressing the first material and the second material through the connected tip portion; andforming the material by mixing the first material and the second material in the connected tip portion before the material exits the connected tip portion, wherein mixing includes using a mixing plate that forms a portion of the connected tip portion and is connected with an end housing portion of the connected tip portion. 2. The method of claim 1, further comprising: directing the first material through the connected tip portion to form a first cone separate from a second cone formed by directing the second material through the connected tip portion; andcausing the first cone and the second cone to intersect external to the connected tip portion. 3. The method of claim 1, further comprising: collecting a first volume of the first material in a first collection volume of the connected tip portion when the first material is expressed from the expressing assembly;wherein expressing the second material through the connected tip portion includes expressing the second material through a first tube positioned with the connected tip portion to extend substantially directly from the second chamber;wherein expressing the first material through the connected tip portion includes expressing the first volume from the first collection volume through a second tube coaxial around the first tube. 4. The method of claim 1, further comprising: providing a second passage of the tip portion, wherein expressing the first material and the second material includes expressing at least one of the first material and the second material through the second passage. 5. The method of claim 1, wherein the tip portion comprises a first tube having a first tube length, and a second tube having a second tube length, the first tube length being different from the second tube length. 6. The method of claim 5, wherein the first tube and the second tube are coaxial. 7. The method of claim 5, wherein forming the material includes allowing one of the first material or the second material to exit through at least one perforation in a wall of the connected tip portion to mix with the other of the first material and the second material. 8. The method of claim 1, wherein the tip portion comprises a first expression port and a second expression port, and forming the material includes expressing the material formed by mixing the first material and the second material through the first expression port and the second expression port of the connected tip portion. 9. The method of claim 8, wherein the material is expressed from at least one of the first expression port and the second expression port at an angle between 45° and 170°. 10. The method of claim 1, wherein forming the material includes forming a first cone of the material expressed through a first expression port, forming a second cone of the material expressed through a second expression port, and intersecting the first cone and the second cone. 11. The method of claim 1, wherein mixing the first material and the second material using the mixing plate includes passing the first material and the second material, respectively, through at least a first channel and a second channel of the mixing plate. 12. The method of claim 1, wherein mixing the first material and the second material includes passing the first material and the second material to a sump of the connected tip portion. 13. The method of claim 12, wherein the sump comprises an angle between 45° and 170°. 14. The method of claim 1, wherein mixing the first material and the second material includes forming a confluence or agitation in the first material, the second material, or both. 15. The method of claim 1, wherein expressing the first material and the second material includes expressing the first material through the connected tip portion independent of expressing the second material through the connected tip portion. 16. The method of claim 1, wherein expressing the first material and the second material includes expressing a volume of the first material through the connected tip portion that is different from a volume of the second material expressed through the connecting tip portion. 17. The method of claim 1, wherein expressing the first material and the second material includes expressing the first material through the connected tip portion at a rate that is different from a rate at which the second material is expressed through the connected tip portion. 18. The method of claim 1, further comprising: providing a first plunger configured to be received within the first chamber and a second plunger configured to be received with the second chamber, wherein expressing the first material and the second material includes permitting the first plunger and the second plunger to independently express, respectively, the first material and the second material through the connected tip portion. 19. The method of claim 1, wherein forming the material includes selecting a volume of the first material to be mixed with a selected volume of the second material. 20. The method of claim 1, wherein forming the material includes substantially mixing the first material and the second material in a sump of the connected tip portion before the material exits the connected tip portion.
