Patent ID: 7559932

Claim:
A method for treating bone, comprising: providing a flowable infill material for infill of an interior region of a bone; loading the infill material into an injector system having a portion positionable within the bone, the injector system comprising a heating element therein and at least one outlet port; controllably applying energy from an energy source to the infill material via the heating element contemporaneously with flowing of the infill material through the injector system and before introducing the flowable infill material into the bone, the applied energy selectively increasing the viscosity of the infill material; and introducing the flowable infill material having the selectively increased viscosity into the bone while controlling the viscosity of the flow of infill material through the controlled application of energy, the introduction of flowable infill material being controlled causing flowing of the flowable infill material, along a flow path through cancellous bone and interdigitating with cancellous bone, in the flow path wherein between an outer region of the flow path and the at least one outlet port in the flow path, the flow path comprises flowable infill material interdigitating with cancellous bone.
