a cartridge releasably coupled to the delivery device, the cartridge defining a lumen therethrough to receive at least a portion of the plunger therein; a receptacle defining a cavity therein for receiving a medical compound; a first tube slidably positionable within the cavity of the receptacle; and a second tube slidably positionable within the first tube, wherein the cartridge is slidably positionable within the second tube. ## Claims ### Claim 1 A medical compound preparation and delivery system, comprising: a delivery device, the device including a depressible trigger operably coupled to move a plunger; a cartridge releasably coupled to the delivery device, the cartridge defining a lumen therethrough to receive at least a portion of the plunger therein; a receptacle defining a cavity therein for receiving a medical compound; a first tube slidably positionable within the cavity of the receptacle; and a second tube slidably positionable within the first tube, wherein the cartridge is slidably positionable within the second tube. ### Claim 2 (depends on 1) The system of claim 1, wherein the cavity of the receptacle is substantially cylindrical. ### Claim 3 (depends on 1) The system of claim 1, wherein the cavity extends entirely through the receptacle, and wherein the system further comprises a base removably coupled to the receptacle to cover a portion of the cavity. ### Claim 4 (depends on 1) The system of claim 1, wherein the cartridge defines an elongated substantially tubular body. ### Claim 5 (depends on 4) The system of claim 4, wherein the cartridge includes an arcuate tip. ### Claim 6 (depends on 1) The system of claim 1, wherein the delivery device includes a ratchet mechanism engageable with the plunger. ### Claim 7 (depends on 1) The system of claim 1, wherein the delivery device includes a locking element configured to secure the cartridge to the delivery device. ### Claim 8 (depends on 1) The system of claim 1, wherein the cavity of the receptacle has a volume between approximately 2 cc and approximately 20 cc. ### Claim 9 (depends on 1) The system of claim 1, wherein the lumen of the cartridge defines a volume between approximately 2 cc and approximately 20 cc. ### Claim 10 (depends on 1) The system of claim 1, wherein the plunger defines a groove at a distal end thereof. ### Claim 11 (depends on 1) The system of claim 1, wherein the plunger includes a sealing element at a distal end thereof. ### Claim 12 (depends on 1) The system of claim 1, wherein each of the cartridge, first tube, and second tube define a tapered end. ### Claim 13 (depends on 1) The system of claim 1, further comprising a base that is releasably engageable with the receptacle. ### Claim 14 (depends on 13) The system of claim 13, further comprising a cap that is releasably engageable with the base. ### Claim 15 (depends on 1) The system of claim 1, further comprising a distal tip accessory that defines a curved spout, wherein the distal tip accessory is releasably engageable with the delivery device to substantially enclose the cartridge therein. ### Claim 16 A method of preparing a medical compound for delivery, comprising: placing a medical compound into a cavity of a receptacle; slidably positioning a first tube into the cavity such that the medical compound is moved into the first tube; slidably positioning a second tube into the first tube such that the medical compound is moved into the second tube; slidably positioning a cartridge into the second tube such that the medical compound is moved into the cartridge; and releasably securing the cartridge to a delivery device, wherein the delivery device includes a depressible trigger operably coupled to move a plunger into the cartridge to controllably dispense the medical compound from the cartridge. ### Claim 17 (depends on 16) The method of claim 16, wherein the medical compound includes bone graft. ### Claim 18 (depends on 16) The method of claim 16, wherein the receptacle includes a substantially cylindrical body. ### Claim 19 (depends on 16) The method of claim 16, wherein the delivery device includes a ratchet mechanism engageable with the plunger. ### Claim 20 (depends on 16) The method of claim 16, wherein the delivery device includes a locking element configured to secure the cartridge to the delivery device.
