Bone graft cartridge and bone graft delivery system
Systems and methods for delivering bone graft material, which utilize a graft material cartridge. The bone graft delivery system comprises an outer delivery unit and a graft material cartridge. The bone graft delivery system is configured to provide a mechanism that loads graft material through a delivery tube and not at the end or outside of it.
1. A bone graft delivery system comprising:
an outer delivery unit comprising a first end, a second opposing end, and a main body therebetween, said outer delivery unit main body having a first portion sized and shaped to hold at least a portion of a graft material cartridge when stored therein;
a graft material cartridge being sized and shaped to fit within a lumen of said outer delivery unit main body, said graft material cartridge comprises an upper member and a second, independent lower member, said graft material cartridge upper member comprises a first portion of a connecting unit and said graft material cartridge lower member comprises a second portion of said connecting unit;
a cap member, said cap member including internal structures for interlocking cooperation with said first portion and second portion connecting units to secure said upper member and said lower member together to form a unitary body defining said graft material cartridge.
2. The bone graft delivery system according to claim 1 , wherein said outer delivery unit main body comprises a second portion.
3. The bone graft delivery system according to claim 2 , wherein said outer delivery unit main body first portion has a circumference which is larger than a main body second portion circumference.
4. The bone graft delivery system according to claim 2 , wherein said outer delivery unit main body second portion terminates in an opening, said outer delivery unit main body second portion opening exposing an outer delivery unit main body second portion internal lumen.
5. The bone graft delivery system according to claim 1 , wherein said outer delivery unit main body second portion includes a pair of guiding posts configured to aid in placement of said the outer delivery unit.
6. The bone graft delivery system according to claim 5 , wherein said guiding posts are two elongated bodies, each protruding outwardly away from said outer delivery unit second end and arranged in a parallel orientation relative to each other.
7. The bone graft delivery system according to claim 1 , wherein said graft material cartridge comprises a first end, a second end, and a main body, said graft material cartridge main body comprising an inner lumen sized and shaped to receive and store bone grafting material therein.
8. The bone graft delivery system according to claim 1 , wherein said graft material cartridge comprises bone grafting material.
9. The bone graft delivery system according to claim 8 , wherein said bone grafting material is an autogenous bone graft material, an allogenic bone material, a xenogenic bone material, or a bone substitute.
10. The bone graft delivery system according to claim 9 , wherein said bone substitute is a demineralized bone material (DBM), demineralized freeze-dried bone allograft (DFDBA), graft composites, bone graft materials with growth factors, bone morphogenic proteins (BMPs); tissue engineered materials.
11. The bone graft delivery system according to claim 8 , wherein said bone grafting material is morselized.
12. The bone graft delivery system according to claim 1 , wherein said first portion and said second portion of said connecting units are threading.
13. The bone graft delivery system according to claim 1 , wherein said graft material cartridge upper member secures to said graft material cartridge upper member lower member by at least one hinge.
14. The bone graft delivery system according to claim 1 , further including a plunger sized and shaped to be inserted and move within said graft material cartridge.
15. The bone graft delivery system according to claim 1 , wherein said graft material cartridge is preloaded with bone grafting material.
16. The bone graft delivery system according claim 15 , wherein said bone grafting material is morselized.
