20090183555 | INTERCONNECT FOR MEMS DEVICE INCLUDING A VISCOELASTIC SEPTUM - Provided is a micro electro mechanical systems (MEMS) device for use with an elongate structure. The MEMS device includes a generally planar substrate, a device wall layer formed upon the substrate, a septum cavity formed in the device wall layer, a channel formed in the device wall layer in fluid communication with the septum cavity, and a septum element disposed in the septum cavity. The septum element is formed of a viscoelastic material. The septum element defines a septum entry surface and a septum exit surface with the septum exit surface being exposed to the channel and disposed between the septum entry surface and the channel. The septum element is without any openings formed through the septum element extending between the septum entry and exit surfaces. Methods of manufacturing and interacting with the MEMS device are also provided. | 07-23-2009 |
20090192493 | IMPLANTABLE DRUG-DELIVERY DEVICES, AND APPARATUS AND METHODS FOR REFILLING THE DEVICES - In various embodiments, a needle is employed in refilling drug-delivery devices. | 07-30-2009 |
20100217209 | DRUG DELIVERY DEVICE WITH IN-PLANE BANDPASS REGULATION CHECK VALVE IN HEAT-SHRINK PACKAGING - A drug delivery device may include a drug reservoir configured to contain and controllably deliver a fluidic drug. A tube may be configured to deliver the fluid from the drug reservoir through a lumen in the tube to another location. A valve wholly within the lumen of the tube may regulates the flow of the fluid through the tube without substantially diverting the direction in which the fluid flows through the tube. The valve may contain only a single member which moves during operation of the valve. The valve may be configured to regulate the flow of fluid in a bandpass manner by allowing fluid to flow through the valve only when the pressure of the fluid is above a minimum and below a maximum. The valve may be held in place within the tube solely by frictional force between the valve and a wall of the tube. | 08-26-2010 |
20100222769 | MEMS ELECTROCHEMICAL BELLOWS ACTUATOR - 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. Methods of making the bellows which utilize stacked sheets are also disclosed. | 09-02-2010 |
20100305550 | MEMS DEVICE AND METHOD FOR DELIVERY OF THERAPEUTIC AGENTS - Embodiments of an implantable device for delivering a therapeutic agent to a patient include a reservoir configured to contain a liquid comprising the therapeutic agent, and a cannula in fluid communication with the reservoir. The cannula is shaped to facilitate insertion thereof into a patient's eyeball. | 12-02-2010 |
20110144617 | MEMS DEVICE AND METHOD FOR DELIVERY OF THERAPEUTIC AGENTS - Embodiments of an implantable device for delivering a therapeutic agent to a patient include a reservoir configured to contain a liquid comprising the therapeutic agent, a cannula in fluid communication with the reservoir, and means for forcing fluid from the reservoir into the cannula. Circuitry for controlling the means for forcing fluid from the reservoir into the cannula may be included. | 06-16-2011 |
20110144619 | MEMS DEVICE AND METHOD FOR DELIVERY OF THERAPEUTIC AGENTS - Embodiments of an implantable device for delivering a therapeutic agent to a patient include a reservoir configured to contain a liquid comprising the therapeutic agent, and a cannula in fluid communication with the reservoir. A valve for maintaining a constant flow rate through the cannula independent of the pressure applied to the device may be included. | 06-16-2011 |
