  • Simultaneous injection and aspiration of viscous fluids in a surgical system
    Patent number: 6290690
    Abstract: A method of injecting a first viscous fluid into a target tissue simultaneous with aspirating a second viscous fluid from the target tissue is disclosed. A surgical system is provided that is capable of supplying pneumatic pressure and vacuum. A first viscous fluid is injected into the target tissue using pneumatic pressure from the system. A mode of operation of the system is changed to provide vacuum and pneumatic pressure. The second viscous fluid is aspirated from the target tissue using vacuum from the system, and the pneumatic pressure remains substantially constant during aspiration. An improved foot pedal for controlling the simultaneous injection and aspiration of viscous fluids is also disclosed.
