1. An apparatus for delivering a bone reinforcing mixture to a bone comprising:
- a tube having a proximal end, a distal end, and a longitudinal axis therebetween,wherein the tube has at least one inner lumen capable of allowing a bone reinforcing mixture to pass through; and
a bone fitting portion having an opening for extending the tube through, a screw-thread portion for screwing through layers of the bone, a stopper that limits the insertion of the bone fitting portion into the bone, a grip portion for assisting in inserting the bone fitting portion into the bone, and at least one valve for relieving a pressure buildup in the bone void during delivery of the bone reinforcing mixture,wherein the screw-thread portion extends into a bone void of the bone, andwherein the tube extends through the bone fitting portion and into the bone.

8. A system for reinforcing a bone comprising:
-
a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least one inner lumen for allowing a bone reinforcing mixture to pass therethrough and a second inner lumen; a bone fitting portion having an opening for extending the tube through and a screw-thread portion for screwing through layers of the bone; an adhesive system engaging the proximal end of the tube for housing the bone reinforcing mixture; and a light source to provide light passing through the second inner lumen to harden the bone reinforcing mixture. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for reinforcing a bone comprising:
-
penetrating the bone at a site adjacent to a weakened or fractured area of the bone to gain access to an interior of the bone; forming a bone void in the interior of the bone having a distal edge and a proximal edge; inserting a bone fitting portion at the penetration site, the bone fitting portion having an opening, a screw-thread portion for screwing through layers of the bone, and at least one relief valve; positioning a catheter having a proximal end, a distal end, and a longitudinal axis therebetween through the opening of the bone fitting portion so the distal end of the catheter is within the bone void; infusing a bone reinforcing mixture through at least one inner lumen of the catheter into the bone void; and removing the catheter from the bone fitting portion. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
