Abstract
A method for reducing small volume subcutaneous leaks of therapeutic fluids during procedures to refill an implantable medical device includes reducing pressure in a reservoir of the device. A refill needle can be percutaneously inserted into a fill port in communication with the reservoir and therapeutic fluid can be delivered through the needle into the reservoir. Reduced reservoir pressure upon withdrawal of the refill needle from the port can result in reduced subcutaneous leakage of the therapeutic fluid.
