Abstract:
1. A bone graft delivery system, comprising: a hollow tube constructed to receive bone graft, said hollow tube having an extended axis and a proximal end and a distal end, said hollow tube having a non-circular interior cross-section from said proximal end to said distal end, said distal end having a distal tip having a substantially tapered distal tip interior surface, said distal end having a distal end interior surface of non-circular cross-section, said hollow tube having one or more lateral openings; a funnel disposed at the proximal end of the hollow tube, the funnel configured to receive bone graft material, the funnel in fluid communication with the proximal end of the hollow tube to deliver bone graft material through the hollow tube; and a plunger adapted for inserting into said proximal end of said hollow tube, said plunger having a distal end having a distal end exterior surface of non-circular cross-section contoured to said distal end interior surface of said hollow tube, said plunger distal end exterior surface of non-circular cross-section forming a substantially congruent fit with said hollow tube non-circular interior cross-section, wherein said hollow tube and said plunger are configured to deliver bone graft material to a graft receiving area through said one or more lateral openings and said one or more lateral openings are located near said distal end of said hollow tube, said one or more lateral openings substantially precluding the delivery of bone graft material directly along said axis of said hollow tube, said plunger precluded from rotating when inserted into said hollow tube.
