  • Publication number: 20130304017
    Abstract: In various embodiments, an injector control system may be configured to control a needle-free injector to inject fluid injectate to a desired penetration depth. The injection control system may also be configured to receive injection performance data and use the injection performance data to make further adjustments to the needle-free injector. In various embodiments, the needle-free injector may be configured to be adjustable according to either an injection pressure and/or a nozzle orifice diameter in order to achieve injection at the desired penetration depth. In various embodiments, the needle-free injector may be configured to inject the fluid injectate according to a combined injection relationship that is both substantially linear between the adjusted pressure and the desired penetration depth and between the nozzle orifice diameter and the desired penetration depth. Other embodiments may be described and claimed.

  • Patent number: 8444699
    Abstract: A bone augment for repairing a bone defect. The bone augment includes a porous body and a metallic liner. The porous body defines a bore and is configured to be intraoperatively shaped to correspond to the bone defect. The metallic liner is injection molded within the bore such that portions of the liner interlock with pores of the porous body. The metallic liner is operable to mount an implant to the bone augment.

  • Patent number: 8105272
    Abstract: 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.

  • Publication number: 20110315269
    Abstract: 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.
