Formulations include those which have a viscosity of about 5 cS or more at about 20° C. and which can have 0.5 ml or more administered by a needle-free injector in about 0.1 second±0.02 seconds.09-04-2008
20130204183DRUG DELIVERY DEVICE AND METHOD FOR ASSEMBLING A DRUG DELIVERY DEVICE - A drug delivery device comprises a first component and a second component, wherein a substance is provided on at least one of the first component and the second component. An inner friction of the substance is great enough to stabilize at least one of the orientation and the position of the first component and the second component with respect to one another. The inner friction of the substance is small enough to allow relative movement of the first component and the second component necessary for the intended operation of the device. Furthermore, a method for assembling a drug delivery device is provided.08-08-2013
20100286604Universal Syringe with Retractable Needle - This invention relates to medical devices useful for infusion therapy and, more particularly, to a syringe that can be selectively used with a retractable needle or with frontal attachment devices such as luer hubs, valves or other connectors in needleless systems.11-11-2010
20100286603KIT AND METHOD FOR PREPARATION OF A DEGARELIX SOLUTION - A kit and method for preparing a Degarelix solution for administration to a patient. The kit includes a first chamber containing lyophilised Degarelix, a second chamber containing water, a syringe for transferring the water from the first chamber to the second chamber, at least one of a hypodermic needle, a safety needle device, or a needleless device for delivery of the Degarelix to the patient, and a mixing apparatus. The mixing apparatus is configured to receive the first chamber to mix the Degarelix and water to produce a Degarelix solution suitable for deliver to a patient. The method includes transferring a volume of water from a first chamber into a second chamber containing lyophilised Degarelix, connecting the second chamber to a mixing apparatus and mixing the water and lyophilised Degarelix for a period of time.11-11-2010
20100063439INJECTION DEVICE - The invention relates to an injection device, especially for a device for injecting an injectable product. Said device comprises a reservoir (03-11-2010
20130158474Intranasal Cartridge Devices - Intranasal delivery devices include dosage forms containing medical compositions for use in the intranasal devices, and methods of delivering medical compositions to the nasal mucosa of users. The devices dispense a predetermined quantity of fluid into the nasal passage of a user, in which the predetermined quantity of fluid is contained in, or produced in a dosage form or blister that is crushed by a plunger with sufficient force to drive the dosage form against a piercing mechanism, piercing the dosage form and forcing the liquid contents from the dosage form and through a delivery channel into a spray to be directed into the nasal passage of a user. The plunger is connected to a trigger device by a linkage that confers a mechanical advantage to the trigger mechanism.06-20-2013
20130190684PISTON FOR A NEEDLELESS VALVE SYSTEM - A piston for a needleless valve system comprising a head portion configured to be disposed in the needleless valve system and controlling fluid flow through the needleless valve system. The head portion comprising a continuous top surface, and an opening disposed proximate the continuous top surface, wherein the continuous top surface is non-planar when the opening is in an open position.07-25-2013
20130190685NEEDLELESS INJECTOR - The present invention relates to a needleless injector. The needleless injector includes: a piston shaft including a plurality of holders on an outer surface in a circumferential direction thereof; a cylinder assembly which slidably receives and supports the piston shaft in the forward and backward directions; a plurality of balls which are received in the cylinder assembly and disposed around the piston shaft, the plurality of balls being movable in a radial direction and inserted into the plurality of holders when the piston shaft is moved in the backward direction; a trigger button slidably coupled to a rear end of the cylinder assembly to form a trigger end interrupting the movement of the balls inserted into the holders in the radial direction, the trigger button releasing the interruption of the trigger end when the piston shaft is slid in the forward direction; a first elastic pressing unit for pressing the piston in the forward direction; and a second elastic pressing unit for pressing the trigger button in the backward direction.07-25-2013
