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.
