Abstract
An implantable pump system employing a flow regulator isolates the regulator sensing chamber from the path of drug flow. This is accomplished by establishing either an independent sensing chamber in the regulator or coupling it to the propellant chamber of the pump. Additionally, a downstream restrictor may be used to provide an additional pressure drop between the regulator and the outlet catheter.
