A pressure applicator for applying pressure to a flowable implant material, e.g., PMMA. A pressure applicator or driver includes a pair of columns which are engageable with one another, preferably by threads to generate a driving pressure. A handle is provided for the operator to grasp and steady the device as he turns the handle to apply pressure to the implantable material within the applicator. A luer-lock or other connecting device is provided for attaching the applicator to a cannula (or a connecting conduit that in turns connects with a cannula) that will deliver the implant material to the desired site. Pressures of about 1000-3000 psi may be generated by this device. |
