are operating properly. If the system is not performing correctly, contact your
doctor.
Therapeutic radiation
The Medtronic MiniMed 2007D Implantable Insulin Pump System has been
tested with therapeutic radiation. These procedures have no effect on the
Pump. However, it is recommended not to focus therapeutic levels of radia-
tion directly over the pump. After such procedures, you should test the Pump
function (e.g., program a “SELF TEST”) to determine that the Pump and PPC
are operating properly. If the system is not performing correctly, contact your
doctor.
Magnetic resonance imaging
You cannot undergo Magnetic Resonance Imaging procedures with the
Medtronic MiniMed 2007D Implantable Pump System.
Pump and catheter under-delivery
Under-delivery or “backflow” may occur when insulin deposits collect in the
pumping mechanism inside your Pump. These deposits affect the vacuum seal
in the pumping mechanism, and can prevent some of the insulin from being
delivered. If the pumping mechanism is unable to seal tightly, the pump will
under-deliver its insulin.
If your Pump is under-delivering insulin, you may feel symptoms of hypergly-
cemia. If this occurs, you should contact your doctor immediately. Your doc-
tor will instruct you on how to manage your blood glucose levels until the
Pump can be corrected.
Another under-delivery condition can also be caused by body fluids or body
tissue collecting at the tip of the Catheter. To correct a Catheter obstruction,
your doctor may need to flush your Catheter with a sterile solution.
Pump electronic or alarm malfunction
If the Pump’s electronic or alarm systems malfunction, Self Test circuitry will
detect the malfunction and may stop the Pump. Notify your doctor immedi-
ately if this occurs. If your doctor cannot correct the malfunction, your Pump
may need to be replaced and you will need to take alternative insulin therapy.
