| 主权项 | 1. An implantable drainage device for draining a patient's cerebro-spinal fluid, the device comprising: a drainage valve comprising a valve member and a valve seat; a control unit suitable for modifying an operating parameter of said valve, at least as a function of a measurement (D) of the fluid flow rate through said valve, said control unit being also suitable for re-evaluating a setpoint flow rate (D*) at regular intervals and/or following a particular event; and an actuator controlled by the control unit, suitable for modifying the operation of said valve as a function of said operating parameter as modified by the control unit; the device including a mass flowmeter suitable for taking said measurement of said flow rate of fluid through said valve. | ||
