Methods for placing materials into bone
First Claim
1. A method comprising accessing cancellous bone through a subcutaneous access path in soft tissue, forming a cavity in cancellous bone including providing a cavity forming tool, advancing the cavity forming tool through the subcutaneous access path into cancellous bone, and manipulating the cavity forming tool to form the cavity, delivering a measured volume of bone filling material into the cavity through the subcutaneous access path including providing a nozzle having an interior bore defining an interior volume sized for containing bone filling material for delivery into the cavity, and advancing the nozzle through the subcutaneous access path, and forming a nested instrument while clearing residual bone filling material from the interior bore including providing an auxiliary tool that can be manipulated independently of the nozzle, and advancing the auxiliary tool through the interior bore of the nozzle.

Abstract
Cancellous bone is accessed through a subcutaneous access path in soft tissue. A cavity is formed in cancellous bone by a cavity forming tool that is advanced through the subcutaneous access path into cancellous bone and manipulated to form the cavity. A measured volume of bone filling material is delivered into the cavity through the subcutaneous access path by a nozzle having an interior bore defining an interior volume sized for containing bone filling material, which is advanced through the subcutaneous access path. A nested instrument is formed while clearing residual bone filling material from the interior bore by an auxiliary tool that can be manipulated independently of the nozzle, which is advanced through the interior bore of the nozzle.
