Methods for placing materials into bone
First Claim
1. A method comprisingaccessing 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, subsequent to the delivering step,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, and thentamping residual bone filling material out of the access path and into the cavity by moving the nested instrument, defined by the nozzle and the auxiliary tool disposed therein, distally through the access path.

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.

3. 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, advancing the nozzle through the subcutaneous access path, and, subsquent to the delivery step, removing the nozzle from the access path, using the removed nozzle to form a nested tamping instrument sized for occupying the subcutaneous access path, and being operatively movable therethrough to force residual bone filling material out of the access path and into the cavity, the using step including providing an auxiliary tool that can be manipulated independently of the nozzle, and advancing the auxiliary tool through the interior bore of the removed nozzle to substantially fully occupy the entire interior bore while clearing residual bone filling material from the interior bore.
