Implantable infusion pump with a propellant chamber, an infusate chamber separated from the latter by an elastic element, a catheter attachment piece, and a throttle path lying between infusate chamber and catheter attachment piece, a switching valve releasing the throttle path, a first pressure sensor lying upstream from the throttle path, and a computer which controls the valve on the basis of a default value calculated for a nominal propellant pressure via an external control device, characterized in that the computer is configured to correct the default value of the control device or the resulting duty ratio as a function of the pressure actually present upstream from the throttle path. |
