A remotely-activated injection device for use in vertebroplasty is provided to inject a flourescent probe material into a patient. The injection device includes a pump defining an injection chamber having an exit opening; an actuator; and a cable having a first end coupled to the actuator, and a second end remotely engaging the pump. The actuator remotely controls the pump by responsive movement of the cable to thereby cause injection of a flourescent probe material from the injection chamber of the pump through the exit opening to the patient.

1. A remotely-activated device for injecting a bone cement into a patient, comprising: a pump defining an injection chamber having an exit opening, the pump having a bone cement for injection being located in the injection chamber, and a piston for driving the bone cement for injection through the exit opening;a hollow bone needle extending from the exit opening for transferring the bone cement for injection directly to a patient;a remote actuator, separate from the pump, and including a base and a lever, the lever having a first portion pivotally-connected to the base; anda housing connecting the actuator to the pump across a distance;whereby pivotal movements of the lever apply a force across the distance through the housing to cause responsive movement of the piston to drive the bone cement for remote injection through the exit opening;wherein the distance is at least about one foot. 2. The device of claim 1 further comprising a cable having a first end coupled to the actuator, and a second end engaging the pump, the actuator controlling the pump by mechanical force of the cable on the pump, causing injection of the bone cement from the injection chamber of the pump through the exit opening. 3. The device of claim 2 further comprising a piston driver engaging the piston to allow axial movement of the piston along a first axis defined by first and second end portions of the injection chamber, wherein the second end of the cable engages the piston driver and the actuator controls the piston driver by responsive movement of the cable to thereby cause axial movement of the piston toward the exit opening of the injection chamber, thereby further causing injection of the bone cement through the exit opening. 4. The device of claim 1, further comprising a rigid rod having a first end engaged to the actuator, and a second end engaging the pump, the actuator controlling the pump by mechanical force of the rigid rod on the pump, causing injection of the material from the injection chamber of the pump through the exit opening. 5. The device of claim 4, wherein the actuator is configured to push the rigid rod in a direction toward the pump to apply a force to the piston. 6. A remotely-activated device for injecting a bone cement into a patient, comprising: a pump defining an injection chamber having an exit opening, the pump having: a) a bone cement for injection being located in the injection chamber;b) a piston for driving the bone cement for injection through the exit opening; andc) a piston driver for engaging the piston to allow axial movement of the piston along a first axis defined by first and second end portions of the injection chamber;a hollow bone needle extending from the exit opening for transferring the bone cement for injection directly to a patient;a remote actuator, separate from the pump, and configured to be held and activated by hand; anda housing connecting the actuator to the pump across a distance;whereby manual activation of the actuator applies a force through the housing to cause responsive movement of the piston to drive the bone cement for remote injection through the exit opening;wherein the piston driver comprises a hydraulic cylinder. 7. The device of claim 1, further comprising an anchor for coupling the pump to a patient. 8. The device of claim 7, further comprising: a needle coupled to the exit opening in the second end portion of the injection chamber; andthe needle being guided to the patient through the anchor. 9. The device of claim 1, wherein the distance is between about one foot and ten feet. 10. The device of claim 1, wherein the distance is at least about two feet. 11. The device of claim 1, wherein the distance is at least about five feet. 12. The device of claim 1, wherein the remote actuator is proximal with respect to the pump from the perspective of an operator of the device. 13. The device of claim 1, wherein the remote actuator base is a handheld base and the remote actuator is configured to be held and activated by hand. 14. The device of claim 6, wherein the distance is at least about one foot. 15. The device of claim 6, wherein the distance is at least about two feet. 16. The device of claim 6, wherein the distance is at least about five feet. 17. A remotely-activated device for injecting a bone cement into a patient, comprising: a pump defining an injection chamber having an exit opening, the pump having a bone cement for injection being located in the injection chamber, and a piston for driving the bone cement for injection through the exit opening;a hollow bone needle extending from the exit opening for transferring the bone cement for injection directly to a patient;a remote actuator, separate from the pump, and including a base and a lever, the lever having a first portion pivotally-connected to the base; anda housing connecting the actuator to the pump across a distance;whereby pivotal movements of the lever apply a force across the distance through the housing to cause responsive movement of the piston to drive the bone cement for remote injection through the exit opening; andwherein the distance is sufficient to allow an operator to operate the remote actuator outside the range of a fluoro-field directed at the pump. 18. The device of claim 1, further comprising an imaging system directed at the pump. 19. The device of claim 18, wherein the imaging system is fluoroscopic. 20. The device of claim 6, wherein the distance is sufficient to allow an operator to operate the remote actuator outside the range of a fluoro-field directed at the pump. 21. The device of claim 1, wherein the bone cement comprises PMMA. 22. The device of claim 1, wherein the bone cement has a paste-like consistency. 23. A method for remotely injecting a bone cement comprising: guiding a hollow bone needle to a desired location within a patient's vertebral body;placing a bone cement for injection into an injection chamber of a device, the device comprising: a pump defining the injection chamber having an exit opening, the device further having a piston for driving the bone cement for injection through the exit opening;the hollow bone needle extending from the exit opening for transferring the bone cement for injection directly to a patient;a remote actuator spaced a distance apart from the pump and including a base and a lever, the lever having a first portion pivotally-connected to the base; anda housing connecting the actuator to the pump;whereby pivotal movements of the lever apply a force through the housing to cause responsive movement of the piston to drive the bone cement for injection through the exit opening;pivotally moving the lever to apply a force across the distance through the housing to cause responsive movement of the piston to drive the bone cement for injection through the exit opening. 24. The method of claim 23, further comprising: anchoring the device to a patient. 25.
