Abstract: A fluid delivery system is provided for delivering fluid to a patient. The system comprises a reservoir for storing the fluid to be delivered to the patient and a fluid discharge device operatively coupled to the reservoir for delivering the fluid from the reservoir to the patient. A controller is configured to operate the fluid discharge device. An input device is in electronic communication with the controller and configured for setting at least one operating parameter of the system. The controller operates the fluid discharge device based on the at least one operating parameter and locks the system after the at least one operating parameter is set such that the at least one operating parameter is unable to be modified. A display is in electronic communication with the controller to at least periodically display a code for resetting the at least one operating parameter. The code is altered at least once during use.

Abstract: An infusion assembly for delivering therapeutic fluid to plural body sites is provided. The assembly includes a positive displacement pump that discharges the therapeutic fluid. The assembly also includes a flow regulator valve including a valve housing that defines a pressure chamber, an inlet bore that opens into the pressure chamber, and first and second outlet passageways. The first and second outlet passageways extend, respectively, from separate first and second outlet openings to a first catheter and a second catheter through which the therapeutic fluid is directed to the body sites. A controller cyclically regulates the operation of the pump so that, in a first phase of each cycle, the pump is actuated so as to cause a fluid pulse to be presented through the inlet bore of the valve housing to the diaphragm and in a second phase of each cycle, the pump is not actuated.

Abstract: A catheter for delivering medication from a fluid source to an anatomical site of a patient and a method of manufacturing the same are provided. The catheter comprises an elongated tube extending between an open proximal end and a closed distal end. The elongated tube includes a catheter wall having an inner surface that bounds a lumen for conveying the fluid from the fluid source. A plurality of openings are defined in the catheter wall to discharge the fluid from the lumen to the anatomical site. A reinforcing coil is disposed within the lumen to improve fluid delivery and provide kink resistance to the catheter. The reinforcing coil has spaced convolutions in an unstretched state. An annular flow space is defined between the reinforcing coil and the inner surface of the catheter wall.
