| 20080208114 | NEEDLE-FREE INJECTION DEVICES AND DRUG DELIVERY SYSTEMS THEREFOR - Needle-free injection devices and drug delivery systems are disclosed. The needle-free injection devices may include a drug delivery system, a power source, an activation system, and a disabling element. The drug delivery system may include a needle-free syringe and a drug storage system. The needle-free syringe may include a plunger slidably disposed within an injection chamber. The injection chamber may include an injection orifice, and the plunger may be configured to expel a volume of fluid from the injection chamber through the injection orifice. The drug storage system may include a storage chamber and an outlet. The drug storage system may be frangibly connected to the needle-free syringe with the outlet proximate to and fluidly connected with the injection orifice. The drug storage system may be configured to inject a fluid from the storage chamber through the outlet, through the injection orifice, and into the injection chamber. | 08-28-2008 |
| 20090137948 | NEEDLE-FREE INJECTION DEVICE WITH AUTO-DISABLE - Needle-free injection devices having a body, an actuation system, and a delivery system including a drive assembly and configured to receive a nozzle assembly. In some embodiments, the drive assembly includes a spring and a support member configured to restrict movement of the spring in a direction non-parallel to a central axis of the spring. In some embodiments, the drive assembly includes a transmission assembly configured to couple a drive source with the actuation system upon engagement of a nozzle assembly with the drive assembly. In some embodiments, the body is configured to acoustically seal an interface between the delivery system and the actuation system. In some embodiments, the body includes a gripping member selectively extendable from the body. | 05-28-2009 |
| 20090137949 | NEEDLE-FREE INJECTION DEVICE WITH NOZZLE AUTO-DISABLE - A nozzle assembly for a needle-free injection device. The nozzle assembly includes a nozzle body including an injectate chamber and one or more outlet orifices and a plunger configured to move through the injectate chamber toward the one or more outlet orifices. In some embodiments, the plunger includes a first portion and a second portion removably joined by a frangible region. In some embodiments, the plunger includes extensions configured to couple the plunger to a drive assembly of a needle-free injection device. | 05-28-2009 |
| 20090247940 | TRIGGERING MECHANISM FOR A NEEDLE-FREE INJECTOR - Needle-free hypodermic jet injection devices having an actuation system to effect an injection from a drug delivery system. The actuation system includes an injection force assembly adapted to transmit a driving force to the drug delivery system. The actuation system further includes a trigger assembly adapted to alter the actuation system between a plurality of configurations including a fired configuration in which the injection force assembly transmits a driving force to the drug delivery system. In some embodiments, the device has a recoil restriction system including a restriction member adapted to couple the recoil restriction system to the trigger assembly and a recoil member coupled to the injection force assembly and movable relative to the restriction member. The restriction member limits movement of the recoil member once the recoil member moves a predetermined distance relative to the restriction member. | 10-01-2009 |
| 20100025503 | NEEDLE-FREE INJECTION DEVICE WITH NOZZLE AUTO-DISABLE - A nozzle assembly for a needle-free injection device. The nozzle assembly includes a nozzle body including an injectate chamber and one or more outlet orifices and a plunger configured to move through the injectate chamber toward the one or more outlet orifices. In some embodiments, the plunger includes a first portion and a second portion removably joined by a frangible region. In some embodiments, the plunger includes extensions configured to couple the plunger to a drive assembly of a needle-free injection device. | 02-04-2010 |
| 20100076374 | INJECTION DEVICE PLUNGER AUTO-DISABLE - A nozzle assembly for a needle-free injection device. The nozzle assembly includes a nozzle body including an injectate chamber and one or more outlet orifices and a plunger configured to move through the injectate chamber toward the one or more outlet orifices. In some embodiments, the plunger includes a first portion and a second portion removably joined by a frangible region. In some embodiments, the plunger includes extensions configured to couple the plunger to a drive assembly of a needle-free injection device. | 03-25-2010 |
| 20110315269 | HIGH WORKLOAD INJECTION SYSTEM - A filling device for a needle-free injector system is provided that is adapted to sterilely deliver a predetermined amount of an injectate from a vial to a plurality of cartridges. The filling device normally includes a single-use fluid path disposed between the vial and a receiving cartridge. The fluid path may include a vial connector adapted to couple to a vial, a filler head, and a conduit connecting the vial connector and filler head. The filling device typically further includes a pump coupled to the fluid path and adapted to propel the injectate from the vial to the receiving cartridge, and a cartridge-advancing element. Activation of the cartridge-advancing element is adapted to sequentially advance empty cartridges into a position opposite the filler head. Also provided are disposable fluid path kits and methods of using the filling device. | 12-29-2011 |
| 20110319860 | INTRADERMAL INJECTION DEVICE - Embodiments herein relate to the field of injections, for instance needle-free injections, and more specifically, to methods and apparatus for spring-driven intramuscular and intradermal injections. Provided in some embodiments are needle-free injectors adapted to deliver intradermal injections, as well as vial adaptors that are adapted to function as spacers when used with a needle-free injection device. | 12-29-2011 |
