摘要： A syringe for performing a medical procedure includes a pressure sensor, a volume sensor, and a compensation circuit. The volume sensor measures a volume of a flowable material that is dispensed from the syringe, the pressure sensor measures a pressure being applied to the flowable material, and the compensation circuit calculates a delivered volume of the flowable material by accounting for system compliance (expansion) as the pressure is increased. By compensating for system compliance in this manner, a syringe can be used in high pressure procedures while still providing accurately controllable material delivery.

摘要： A system for performing a minimally invasive surgical procedure comprises a cannula, a bone filler material delivery nozzle for performing the procedure through the cannula, and a retainer for securing the delivery nozzle relative to the cannula. The retainer eliminates the need to manually stabilize and position the delivery nozzle during the procedure, thereby allowing the physician to perform the procedure outside of the fluoroscopic radiation field used to visualize the procedure location. The retainer can be attached to the cannula, and can provide either selective or constant clamping force onto the delivery nozzle.
