A bone cement delivery device (16,16a,16b,16c,16d,16e,16f) including a syringe body (58), a plunger (60), and a driving system (62) connected to the plunger (60) and sliding the plunger (60) within the syringe body (58) in a displacement-controlled and continuous manner to produce a steady flow of bone cement out of the syringe body (58). Also, a bone cement delivery device (16,16a,16b,16c,16d,16e,16f) including at least one sensor (18,18a,18b,18c,18d, 18e) for measuring a physical parameter of the bone cement within the body (58), the at least one parameter being indicative of a viscosity of the bone cement, and a display unit (22) receiving data from the sensor (18,18a,18b,18c,18d,18e) and displaying at least one of the physical parameter and the viscosity of the bone cement. Improved medical cannulae (12,12a,12b), an improved control system (102) for a bone cement delivery device (16,16a,16b,16c,16d,16e,16f), an improved cement delivery system (10) and related methods are also described. |
