| 20130046239 | Fluid Delivery Device - A fluid delivery device comprises a housing having a fluid reservoir. A needle is in fluid communication with the fluid reservoir in an engaged position and out of fluid communication with the fluid reservoir in armed and storage positions. A proximal end of a biasing member is coupled to the housing and a distal end of the biasing member is configured to deliver a force to the fluid reservoir. A piston member extends through the biasing member and is coupled to the distal end of the biasing member. The piston member is fixed with respect to the housing in a locked position such that the biasing member does not deliver the force to the fluid reservoir and moveable with respect to the housing in a released position such that the biasing member delivers the force to the fluid reservoir. Transitioning the needle from the storage position to the armed position transitions the piston from the locked position to the released position. | 02-21-2013 |
| 20110306929 | Fluid Delivery Device Needle Retraction Mechanisms, Cartridges and Expandable Hydraulic Fluid Seals - A fluid delivery device includes an automatic needle retraction mechanism configured to automatically retract a delivery end of a needle into a housing. In one embodiment, the needle assembly is configured to automatically withdraw the delivery end of the needle into the housing upon an actuator moving from the first position to the second position. In one embodiment, the needle assembly is configured to automatically withdraw the delivery end of the needle into the housing upon decoupling a bottom surface of the housing from a skin surface. | 12-15-2011 |
| 20110172634 | INJECTION SYSTEMS - The invention in general relates to various injection systems and devices that can be used, for example, in needleless injection systems for human, and for domestic and farm animals. In certain embodiments, the invention provides an injection system comprising: an injector defining a first cavity in fluid communication with an orifice configured for needleless injection; a housing defining a second cavity, the housing different than the injector; a first movable member between the first cavity and the second cavity, wherein the first movable member is configured to transfer a fluid from the second cavity to the first cavity; and wherein the first movable member is configured to be substantially stationary until the first movable member is moved by a propellant. | 07-14-2011 |
| 20110137287 | MULTI-CARTRIDGE FLUID DELIVERY DEVICE - A fluid delivery device for administering a first medicament and a second medicament includes a first fluid reservoir configured to contain the first medicament and a second fluid reservoir configured to contain the second medicament. The fluid delivery device may include one or more basal drive mechanisms to provide a basal delivery of one or more of the first and second medicaments. The fluid delivery device may further include one or more bolus drive mechanisms to provide a bolus delivery of one or more of the first and second medicaments. | 06-09-2011 |
| 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 |
