System integrates motor-driven coarse manipulators and oil hydraulic fine manipulators. Device comprises coarse/fine drive units, control units, and power supply. Operated by clinicians in laboratory settings to manipulate microtools during procedures. Provides mechanical assistance for positioning; does not perform automated analysis or decision-making. ## Clinical Evidence No clinical data. Bench testing only. ## Technological Characteristics System consists of motor-driven coarse manipulators and oil hydraulic fine manipulators. Includes coarse/fine drive units, control units, and power supply. X, Y, and Z-axis movement for both coarse (22mm range) and fine (10mm range) operations. Non-software controlled mechanical/hydraulic system. ## Regulatory Identification Assisted reproduction micromanipulators are devices intended to control the position of an assisted reproduction microtool. Assisted reproduction microinjectors are any device intended to control aspiration or expulsion of the contents of an assisted reproduction microtool. ## Special Controls *Classification.* Class II (special controls) (design specifications, labeling requirements, and clinical testing). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 884.9. ## Predicate Devices - MM-89 Motor drive Manipulator ([K002291](/device/K002291.md)) - MMO202ND Three axis Hanging Joystick Oil Hydraulic Micromanipulator ([K002659](/device/K002659.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
