Bone treatment systems and methods
First Claim
1. A method for injecting bone cement into a bone, comprising:
- mixing components of a bone cement to begin polymerization of the bone cement;
inserting at least a portion of an injector body into a bone, the injector body comprising a mechanical flow control mechanism configured to generate a flow rate signal of bone cement flowing through the injector body;
flowing bone cement through the injector body into the bone, comprising flowing bone cement into the injector body with a flow drive mechanism, the flow drive mechanism being separate from the mechanical flow control mechanism;
generating a flow rate signal with the mechanical flow control mechanism corresponding to the flow of bone cement through the injector body; and
modulating an application of thermal energy to the bone cement flowing through the injector body based at least in part on the flow rate signal.

Abstract
Systems and methods for delivering bone cement into a bone can include a handle body defining a flow path, a thermal emitter in the handle body to apply energy to bone cement passing through the flow path, a source of bone cement and an injection cannula. The cannula can be in communication with the flow path such that inserting the cannula into a bone can allow a flow of bone cement therethrough to an opening at a distal end of the cannula. Other systems and methods for delivering bone cement into a bone can include an injector body with a handle portion, and a cannula, a bone cement container, a low pressure drive mechanism configured to effect a flow of bone cement from said container to the injector body and a high pressure drive mechanism configured to effect a flow of bone cement through the injector body into the bone.
