Convergent tunnel guide apparatus and method

A tunnel guide apparatus for creating convergent tunnels in a bone at a target location, comprising:

• a first tubular bullet member comprising a lumen, the first bullet member disposed in a first plane and slidably adjustable relative to said bone in order to contact said bone and operable to aim a guide pin through said bone along a first path to form a first tunnel in said bone;
• an outrigger member slidably disposed on a guide arc member, the outrigger member movable on the guide arc member in an arcuate path relative to the first tubular bullet member, the arcuate path disposed in the first plane;
• a second tubular bullet member comprising a lumen, the second bullet member slidably adjustable relative to said bone in order to contact said bone and operable to aim a guide pin through said bone along a second path to form a second tunnel in said bone, the second tubular bullet member removably and slidably attached to the outrigger member wherein the second tubular bullet member is laterally spaced away from the first tubular bullet member, wherein said first and second bullet members are positioned such that said first and second tunnels are convergent;
• and
• a guide arm member disposed on a distal portion of the guide arc member,
• wherein said first and second bullet members and said guide arm member are adjustable on said guide arc member for forming said first and a second tunnels in said bone.

A method of forming convergent tunnels in a bone at a target location, said method comprising:

• attaching a tunnel guide apparatus onto said bone, said tunnel guide apparatus comprising:
• a first bullet member operable to aim a first guide pin through said bone along a first path to form a first tunnel in said bone, the first tubular bullet member disposed in a first plane;
• an outrigger member slidably disposed on a guide arc member, the outrigger member movable on the guide arc member in an arcuate path relative to the first tubular bullet member, the arcuate path disposed in the first plane;
• and
• a second bullet member operable to aim a second guide pin through said bone along a second path to form a second tunnel in said bone, the second tubular bullet member removably and slidably attached to the outrigger member wherein the second tubular bullet member is laterally spaced away from the first tubular bullet member, wherein said first and second bullet members are positioned such that said first and second tunnels are convergent;
• and
• slidingly adjusting the outrigger member along the guide arc member relative to the first tubular member;
• slidingly adjusting said first and second bullet members relative to said bone in order to contact said bone;
• inserting said first guide pin through said first bullet member to form said first tunnel;
• and
• inserting said second guide pin through said second bullet member to form said second tunnel.
