Methods for injecting flowable materials into bones
First Claim
1. A method of introducing a flowable material into a targeted bone treatment site, comprising the steps ofmixing together at least first and second components of the flowable material;
- introducing the flowable material into a body having an interior bore for containing the flowable material;
controlling the mean temperature of the flowable material within the interior bore; and
ejecting the flowable material from the interior bore into the targeted bone treatment site.

Abstract
A tube body includes an interior bore to carry a material flow into bone. The tube body includes a dispensing end having an opening communicating with the bore to dispense the material flow. One embodiment provides a cutting element, which extends in the opening to permit passage of the material flow and to sever the material flow in response to rotation of the tube body. Another embodiment deflects the dispensing end from the main axis of the tube body, to facilitate targeted introduction of flowable material, even when the access path does not align the tube body along the natural geometric axes of the treatment site. Another embodiment provides a connector having a rotating fitting, which releasably connects the tube body to a cement injecting tool. The rotating fitting allows the physician to rotate the injection nozzle assembly to control orientation and position in the treatment site, without rotating the associated injection tool itself.

wherein the controlling step comprises cooling the flowable material within the interior bore. -
4. The method of claim 1
wherein the controlling step comprises maintaining the flowable material at a substantially constant temperature. -
5. The method of claim 1
wherein the flowable material undergoes an exothermic reaction subsequent to mixing of the at least first and second components.
