BONE TREATMENT SYSTEMS AND METHODS
First Claim
1. A system for delivering bone fill material into a bone, comprisingan injector body comprising a handle portion and an elongated cannula attached to the handle portion, at least a portion of the cannula percutaneously insertable into a bone;
- a flow control mechanism disposed in the injector body and configured to generate a flow rate signal of bone fill material flowing through the injector body;
a thermal energy emitter disposed in the injector body and configured to apply energy to the bone fill material flowing through the injector body; and
a controller configured to receive the flow rate signal from the flow control mechanism and configured to modulate at least one of the flow rate of bone fill material through the injector body and the energy applied by the thermal energy emitter to the bone fill material 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.

18. A method for injecting bone cement into a bone, comprising:
-
inserting at least a portion of an injector body into a bone, the injector body comprising a 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; generating a flow rate signal corresponding to the flow of bone cement through the injector body; and modulating the application of thermal energy to the bone cement flowing through the injector body based at least in part on the flow rate signal. - View Dependent Claims (19, 20, 21, 22, 23, 24)

26. A method of delivering bone fill material into a bone, comprising:
-
inserting at least a portion of an injector body into a bone, the injector body comprising a PTCR or NTCR material; flowing a bone fill material through the injector body into the bone; and measuring an electrical parameter of the PTCR or NTCR material in response to heat transfer from the flow of bone fill material to the PTCR or NTCR material to thereby determine a selected parameter of the bone fill material flow. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
