Abstract
A self-contained apparatus and corresponding methods are provided for delivering viscous fluids in a controlled manner, such as delivering a viscous fluid in a surgical setting. The self-contained apparatus can include a motion following pressure regulator that allows for linear control of a regulated pressure. The regulated pressure can be used for dispensing a viscous fluid from a syringe that is coupled to the self-contained apparatus. The pressure regulator regulates a pressure derived from a pressurized fluid reservoir located at least partially within a housing of the apparatus. This allows the viscous fluid to be delivered using pressure to provide a driving force greater than a force easily delivered manually, while still allowing a surgeon to retain fine control over the rate of viscous fluid delivery.
