Abstract:
1. A system for performing vertebroplasty, comprising: a steerable injection needle configured for one hand operation including an elongate shaft having a proximal portion having a proximal end and a deflectable distal portion having a proximal end distal end, and an opening from which bone cement can exit from the distal portion, wherein the elongate shaft further comprises a first longitudinal axis extending from the proximal end of the proximal portion to the proximal end of the deflectable distal portion, the steerable injection needle further comprising an input port having a second longitudinal axis spaced apart from and at an angle with respect to the first longitudinal axis of the steerable injection needle for receiving bone cement from a cement dispensing pump, wherein the elongate shaft from the proximal end of the deflectable distal portion to the distal end is movable from a first substantially straight configuration to a second configuration not substantially coaxial with the proximal portion, wherein the steerable injection needle further comprises an adjustment control configured to move the distal portion of the elongate shaft from the first configuration to the second configuration, the adjustment control located proximal on the injection needle relative to the input port; a cement dispensing pump configured to house a first bone cement component and a second bone cement component; and a mixing nozzle for mixing the first bone cement component and the second bone cement component into a bone cement composite.
