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; and

    a 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.
