An implantable blood monitoring and medication administering system includes an infusion device (2) which is implantable beneath the skin of a human or animal and which contains medication. A catheter (4) which is implantable in a vessel V is connected to the infusion device. An information transmitting sensor (22) is located in the catheter (4) and is connected to a microprocessor (8) within the system which controls a pump (10) for first withdrawing blood from the vessel V and submitting it to the sensor (22) and then returning the withdrawn blood to the vessel V along with a predetermined amount of medication, the pump may act to pump medication as well as blood or to pump blood alone. In the latter instance, a second pump (44) acts to pump the medication.
