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.

Dependent claims

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.
