  • Publication number: 20100222769
    Abstract: An implantable fluid delivery system may include a fluid reservoir configured to hold a supply of fluid, to dispense that fluid under the control of an actuator, and to be implanted within the body of a living host. An actuator within the fluid reservoir may cause the fluid to be controllably dispensed from the fluid reservoir. The actuator may include a bellows configured to expand in a direction when inflated. The bellows may have folds with surfaces which run substantially perpendicular to the direction of expansion in a collapsed state and which define a stacked set of convolutions. Each convolution may have a collapsed height of no more than 1 mm and a width perpendicular to the direction of expansion of no more than 8 mm. Electrodes may be configured to come in electrical contact with an electrolyte within the bellows and to cause electricity to run through the electrolyte, thereby causing the electrolyte to break down into a gas and, in turn, to cause the bellows to expand.

  • Publication number: 20080039792
    Abstract: An implantable device for delivering a therapeutic agent to a patient is provided. The device includes a reservoir configured to contain a liquid comprising the therapeutic agent. The device further includes a cannula in fluid communication with the reservoir. The cannula has an outlet configured to be in fluid communication with the patient. The device further includes a first electrode and a second electrode, at least one of the first electrode and the second electrode is planar. The device further includes a material in electrical communication with the first and second electrodes. A voltage applied between the first electrode and the second electrode produces gas from the material, the gas forcing the liquid to flow from the reservoir to the outlet.
