A syringe assembly for administering a variety of fluids includes a syringe provided with a plurality of flow-isolated chambers, each of which is in flow communication with a respective lumen of a multi-lumen needle located downstream from the syringe. Each lumen is flow-isolated from the rest of the lumens and guides a respective one of the variety of fluids toward an outlet port formed in the needle so that the fluids mix with one another only upon exiting the outlet port.

1. A syringe assembly for delivering a variety of fluids to a desired location, comprising:a syringe configured to have a plurality of flow isolated chambers each receiving a respective one of the variety of the fluids; anda needle formed with spaced upstream and downstream ends defining therebetween a length of the needle, the needle having a plurality of flow isolated lumens each in flow communication with a respective chamber and extending a length of the needle from the upstream end toward and joining one another adjacent to the downstream end of the needle whereinthe syringe has a body defining the plurality of flow isolated chambers in flow communication with the needle; and,the downstream portion of the body is provided with a frustoconical cross section narrowing toward the needle, a fluid impermeable partition extending through the needle and terminating adjacent to the downstream end of the needle to define the plurality of lumens.2. The syringe assembly of claim 1, further comprising a plurality of plungers each received in a respective one of the plurality chambers and operative to create a positive pressure sufficient to drive fluid from the respective chamber along the lumen into the downstream end of the needle, wherein the downstream end of the needle is provided with an outlet port.3. The syringe assembly of claim 2, wherein the plurality of plungers are selectively actuable to guide the variety of fluids in a sequential manner towards the outlet port of the needle.4. The syringe assembly of claim 2, wherein the plurality of plungers are simultaneously actuable to guide the variety of fluids out from the plurality of chambers of the syringe through the plurality of lumens of the needle into the downstream end of the needle wherein the variety of fluids mix with one another upon exiting the outlet port located in the vicinity of the desired location.5. The syringe assembly of claim 4, further comprising a harness operative to selectively couple the plurality of plungers simultaneously displaceable within respective flow isolated chambers of the syringe.6. The syringe assembly of claim 4, wherein the plurality of chambers includes at least two chambers.7. The syringe assembly of claim 1, wherein the body and the needle form a monolithic housing.8. The syringe assembly of claim 1, wherein the body and the needle are removably attached to one another in a leak-free manner, the needle being provided with a fluid impermeable partition sealingly coupled to the fluid impermeable partition of the syringe.9. The syringe assembly of claim 1, wherein the syringe has separate syringe units each defining a respective one of the plurality of flow isolated chambers, the upstream end of the needle being provided with a flange having fluid guiding channels sealingly attached to the flow isolated chambers and the lumens to convey fluid therebetween.10. The syringe assembly of claim 9, wherein the separate syringe units each are detachably coupled to the flange provided with a plurality of sockets.11. The syringe of claim 10, wherein the separate syringe units each are displaceably mounted to a respective socket of the flange, whereas a user is able to displace the separate syringe units relative to one another.12. A method of delivering a variety of fluids to a desired location comprising the steps of:providing a syringe having a plurality of flow isolated chambers;supplying the variety of fluids so that each of the plurality of flow isolated chambers receives a respective one of the variety of fluids;providing a needle having a plurality of lumens in flow isolation with one another, each of the lumens being in flow communication with a respective chamber and having a cross-section substantially smaller than a cross-section of the respective chamber, the lumens extending a length of the needle and joining one another adjacent to an outlet port formed in a downstream end of the needle whereinthe syringe has a body defining the plurality of flow isolated chambers in flow communication with the needle; and,the downstream portion of the body is provided with a frustoconical cross section narrowing toward the needle, a fluid impermeable partition extending through the needle and terminating adjacent to the downstream end of the needle to define the plurality of lumens; andguiding the variety of fluids through the flow isolated chambers via respective lumens into the downstream end of the needle.13. The method of claim 12, wherein the variety of fluids are guided simultaneously, whereas the fluids are mixed in the downstream end of the needle upon exiting the outlet port.14. The method of claim 12, wherein the variety of fluids are guided selectively in a sequential manner.15. The method of claim 12, further comprising the step of displacing the flow isolated chambers relative to one another.16. The method of claim 12, wherein the variety of fluids react with one another upon contact at the downstream end of the needle.17. The method of claim 16, wherein the variety of fluids reacting with one another includes fibrin and platelets to form the glue-like material.18. The method of claim 16, wherein the syringe and the needle form a monolithic body or a multi-part body, in which the syringe and the needle are detachably coupled to one another.19. A syringe assembly for delivering a variety of fluids to a desired location, comprising:a syringe configured to have a plurality of flow isolated chambers each receiving a respective one of the variety of the fluids; anda needle formed with spaced upstream and downstream ends defining therebetween a length of the needle, the needle having a plurality of flow isolated lumens each in flow communication with a respective chamber and extending a length of the needle from the upstream end toward and joining one another adjacent to the downstream end of the needle; wherein,the syringe has a body defining the plurality of flow isolated chambers in flow communication with the needle; and,a fluid impermeable partition extends through the needle and terminates adjacent to the downstream end of the needle to define the plurality of lumens.
