You can replenish any medical fluid in the pump via percutaneous access to the pump refill septum and reservoir after implantation of the pump. So, long-term drug infusion can continue until the installed battery life has run out. The reservoir is elastic and configured in such geometry as to allow gentle palpation to confirm an approximate level of fluid in the reservoir.
The technology driving the infusion is a patented "Rotary Finger" method. This method is a unique form of peristalsis. The precise "micro-stick" pushes a rubber tube in the pump in a uniform and sequential manner.
The accuracy of iPRECIO is +/-5%.
