Fusion cage with combined biological delivery system

A combination bone graft insertion and implant insertion apparatus 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 uniform interior cross-section from said proximal end to said distal end, said hollow tube of single-piece construction;
• a substantially hollow implant detachably interconnected to the distal end of the hollow tube, said implant constructed to receive bone graft from said hollow tube, said implant having at least two openings having an upper and a lower end located on opposite lateral sides of said implant, said implant having striations on a plurality of implant surfaces, said implant having a tapered distal end which spans the extended axis and forms the most distal end of the combination bone graft insertion and implant insertion apparatus;
• and
• a plunger adapted for inserting into said proximal end of said hollow tube along the extended axis, said plunger having a distal end exterior surface of cross-section contoured to said interior cross-section of said hollow tube, said plunger of single-piece construction with a distal exterior tip, said plunger distal end exterior surface of cross-section forming a substantially congruent fit with said hollow tube uniform interior cross-section,
• wherein said hollow tube, said substantially hollow implant and said plunger are configured to deliver bone graft material to a graft receiving area into the interior of the substantially hollow implant and through the at least two openings of said substantially hollow implant when the plunger is advanced from the proximal end to the distal end of the hollow tube along the extended axis,
• wherein the distal exterior tip of said plunger is configured to remain always proximal to the tapered distal end of said substantially hollow implant when said plunger is inserted into said hollow tube and said substantially hollow implant is attached to said hollow tube.

A combination bone graft delivery and implant insertion apparatus for integrated delivery of bone graft material to a spinal surgical site and for disposing an implant to a spinal surgical site, 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 uniform interior cross-section from said proximal end to said distal end;
• a substantially hollow implant for use in spinal surgery detachably interconnected to the distal end of the hollow tube, said implant constructed to receive bone graft from said hollow tube and constructed to be disposed in a spinal surgical site, said implant having at least two pairs of implant openings, each pair of implant openings located on opposite sides of said implant, said implant configured to fit between a spinal disk space of a spinal surgical site, said implant having striations on a plurality of surfaces adjacent at least one pair of the at least two pairs of implant openings, said hollow implant having a tapered distal end;
• and
• a plunger adapted for inserting into said proximal end of said hollow tube and deliver bone graft to an interior of the implant, said plunger having a distal end exterior surface of cross-section contoured to said interior cross-section of said hollow tube, said plunger distal end exterior surface of cross-section forming a substantially congruent fit with said hollow tube uniform interior cross-section, wherein said hollow tube, said implant and said plunger are configured to deliver the bone graft material to the spinal surgical site through the at least two pairs of implant openings of said implant after passing through the interior of the implant, wherein bone graft material within said hollow tube is delivered to the interior of the implant and to the spinal surgical site, wherein the implant is detached from the hollow tube and disposed in the spinal surgical site, wherein the spinal surgical site comprises a spinal disk space.
