The bone delivery device may include a cannula and a cartridge in fluid communication with the cannula, wherein the cartridge comprises a base containing one or more delivery channels configured to receive bone material. The bone material within the delivery channel(s) is compacted to a second diameter smaller than the first diameter. The method includes actuating the compacted bone material from the cartridge through the cannula to deliver the bone material to an implantation site. ## Claims ### Claim 1 A bone delivery device, comprising; a cannula defining a first diameter; a frame extending from a proximal end of the cannula, the frame including a side opening; and a cartridge comprising a plurality of delivery channels therein that define second diameters smaller than the first diameter, each delivery channel configured to receive bone material, wherein the cartridge is insertable into the frame through the side opening and slidable laterally through the side opening for moving the cartridge to any one of a plurality of delivery positions within the frame that each correspond to one of the plurality of delivery channels in the cartridge so that, via said moving, a user can separately longitudinally align each of the plurality of delivery channels with the cannula so as to be in fluid communication with the cannula for advancing the bone material from the respective delivery channel into the cannula. ### Claim 2 (depends on 1) The bone delivery device of claim 1, wherein an outer surface of the cartridge includes a grip feature comprising a tactile surface. ### Claim 3 (depends on 1) The bone delivery device of claim 1, wherein the first diameter ranges from 1 mm to 12 mm. ### Claim 4 (depends on 3) The bone delivery device of claim 3, wherein the first diameter ranges from 3 mm to 6 mm. ### Claim 5 (depends on 1) The bone delivery device of claim 1, wherein the plurality of delivery channels are non-parallel with one another in the cartridge. ### Claim 6 (depends on 1) The bone delivery device of claim 1, wherein the cartridge includes a base and a lid that combine to form the plurality of delivery channels. ### Claim 7 (depends on 6) The bone delivery device of claim 6, wherein the plurality of delivery channels each include a chamfered edge formed in the base. ### Claim 8 A bone delivery device, comprising; a cannula including an open distal end through which a bone material can travel to exit the bone delivery device; a frame extending from a proximal end of the cannula, the frame including a side opening; and a cartridge including a plurality of longitudinal delivery channels therein for receiving the bone material, the cartridge insertable into the frame through the side opening, the cartridge further slidable laterally through the side opening for moving the cartridge to any one of a plurality of delivery positions within the frame that each correspond to one of the plurality of longitudinal delivery channels in the cartridge so that, via said moving, a user can separately longitudinally align cach of the plurality of longitudinal delivery channels with the cannula so as to be in fluid communication with the cannula for advancing the bone material from the respective longitudinal delivery channel into the cannula. ### Claim 9 (depends on 8) The bone delivery device of claim 8, wherein the plurality of longitudinal delivery channels are non-parallel with one another in the cartridge. ### Claim 10 (depends on 8) The bone delivery device of claim 8, wherein the cartridge includes a base and a lid that combine to form the plurality of longitudinal delivery channels. ### Claim 11 (depends on 10) The bone delivery device of claim 10, wherein the plurality of longitudinal delivery channels each include a chamfered longitudinal edge formed in the base. ### Claim 12 (depends on 8) The bone delivery device of claim 8, wherein the cannula has a first diameter, and wherein each of the plurality of longitudinal delivery channels has a second diameter smaller than the first diameter. ### Claim 13 (depends on 12) The bone delivery device of claim 12, wherein the first diameter is less than 6 mm. ### Claim 14 (depends on 8) The bone delivery device of claim 8, wherein the cannula has a first diameter ranging from 1 mm to 12 mm. ### Claim 15 (depends on 14) The bone delivery device of claim 14, wherein the first diameter ranges from 3 mm to 6 mm.
