Selective tissue removal treatment device

Method and system for controllably administering and/or withdrawing fluid from a patient. In one embodiment, the system may include a needle assembly, an ultrasound imager, a fluid supply storage unit, a waste storage unit, a fluid pump, and a foot pedal assembly. A syringe may serve as the fluid supply storage unit and the waste storage unit. The pump may include a bi-directional motor and a gear coupled to the motor. The gear may be engageable with a rack on the syringe plunger to drive the plunger either for fluid aspiration or infusion. Depression of one portion of the foot pedal assembly causes the motor to drive the gear in one direction, and depression of another portion of the foot pedal assembly causes the motor to drive the gear the other direction. The system may include a control device to keep pressure in the fluid path from exceeding a limit.
