| 20090118672 | Microneedle array patch - Microneedle devices for transport of molecules, including drugs and biological molecules, across tissue, are provided. The microneedle devices permit drug delivery or removal of body fluids at clinically relevant rates across skin or other tissue barriers, with minimal or no damage, pain, or irritation to the tissue. Microneedles can be formed of biodegradable or non-biodegradable polymeric materials or metals. In a preferred embodiment, a microneedle device includes a plugging element comprising a platform including a plurality of microneedle plugs for preventing skin or other tissue barriers from entering the hollow microneedles. In another preferred embodiment, a microneedle device includes a plurality of bioerodible elements for temporarily plugging the hollow microneedles, thereby preventing skin or other tissue barriers from entering the hollow microneedles. | 05-07-2009 |
| 20090157005 | HYDRAULICALLY ACTUATED PUMP FOR LONG DURATION MEDICAMENT ADMINISTRATION - Presently disclosed is a hydraulic pump device and its use thereof, especially in a fluid delivery system. In one embodiment, the fluid delivery system is an inexpensive, single-use device for slow dosing medicament applications. The fluid delivery system may employ a spring-compressed bellows crank or other combination of simple mechanisms operating according to the well-known peristaltic principle to force a volume of ultrapure bio-inert hydraulic fluid through an aperture, thereby expanding one chamber of a two chamber hydraulic cylinder. The second, fluid storage chamber, containing the medicament, is emptied through a conventional orifice in response to the expansion of the pump chamber. The medicament may thence flow through any suitable infusion set into a patient removeably attached thereto. | 06-18-2009 |
| 20090187160 | METHODS AND DEVICES FOR DELIVERING AGENTS ACROSS BIOLOGICAL BARRIERS - The invention provides for microneedle devices for delivering agents across biological barriers. The microneedles include agent reservoirs integrated into the bodies of the microneedles, themselves. | 07-23-2009 |

| 20100217191 | HYDRAULICALLY ACTUATED PUMP FOR FLUID ADMINISTRATION - A fluid delivery device comprises a hydraulic pump chamber having a hydraulic fluid. A fluid reservoir is coupled to the hydraulic pump chamber and is configured to contain a fluid deliverable to a patient. A first actuator is coupled to the hydraulic pump chamber and is configured to pressurize the hydraulic pump chamber and configured to transfer energy through the hydraulic pump chamber to the fluid reservoir. A second actuator is coupled to the hydraulic pump chamber and is configured to pressurize the hydraulic pump chamber and configured to transfer energy through the hydraulic pump chamber to the fluid reservoir. | 08-26-2010 |
