FLOW ACTUATED VALVE FOR IMPLANTABLE DRUG DELIVERY DEVICE

摘要

An "MRI-safe" implantable infusion apparatus and method that includes a flow actuated valve (FAV) that closes to prevent a free flow of infusate to a patient during an MRI procedure, and a release mechanism that opens the valve so that the device may return to normal operation following the MRI procedure. In this manner, patient safety is improved and the inconvenience of having to empty the pump reservoir before undergoing an MRI procedure may be avoided.
