20100324496DOSE SETTING MECHANISM FOR PRIMING A DRUG DELIVERY DEVICE - A method and system for providing a drug delivery device. The drug delivery device comprises a dose setting mechanism comprising a spindle and a cartridge holder coupled to the dose setting mechanism. The cartridge holder comprising a cartridge having a movable bung at one end of the cartridge. The cartridge holder must be rotated before a dose may set with the dose setting mechanism.12-23-2010
20100324497BIASING MECHANISM FOR A DRUG DELIVERY DEVICE - A method and system for biasing a cartridge in a drug delivery device. An element for biasing a cartridge in a cartridge housing of a drug delivery device is provided. This non-plastic element does not comprise a coil spring. A self retained element for providing a spring bias to a cartridge in a cartridge holder of a drug delivery device comprises a first member having a shape that allows passage of a spindle of the drug delivery device. A portion of the first member is self retained by an internal surface of the drug delivery device. The self retained element biases the cartridge against an inner surface of the cartridge holder. This cartridge could be a removable cartridge.12-23-2010
20100331786SPINDLE AND BEARING COMBINATION AND DRUG DELIVERY DEVICE - An improved spindle and bearing combination for a drug delivery device is provided that has a first connection between the spindle and bearing comprising a web and a second connection that replaces the first connection when the web is severed that allows the spindle to rotate relative to the bearing.12-30-2010
20100331788RESETTABLE DRUG DELIVERY DEVICE - A resetting mechanism for a reusable drug delivery device. The device comprises a spindle and a spindle guide engaging the spindle. During a resetting step of the resetting mechanism, the spindle rotates while the spindle guide does not rotate.12-30-2010
20100331790SPINDLE FOR A DRUG DELIVERY DEVICE - A spindle for driving a bung of a cartridge. The spindle includes a generally circular shaft having an outer surface. The generally circular shaft extends from a distal end to a proximal end of said circular shaft. A first helical groove is provided along a first portion of the outer surface. The first helical groove having a first pitch. A second helical groove provided along a second portion of the outer surface of the generally circular shaft. The second helical groove overlapping the first helical groove. The second helical groove having a second pitch.12-30-2010
20100331791DRUG DELIVERY DEVICE WITH DOSE DIAL SLEEVE ROTATIONAL STOP - A method and system for a dose setting mechanism of a drug delivery device. The dose setting mechanism includes an inner housing having a helical groove along an external surface of the housing. The inner housing includes a rotational stop feature near one end of the helical groove. The dose setting mechanism also includes a dial sleeve rotatably engaged with the helical groove of the inner housing. When a user rotates the dial sleeve to select a dose, the rotational stop member prevents the user from selecting a dose greater than a pre-defined maximum selectable dose.12-30-2010
20100331792DRUG DELIVERY DEVICE INNER HOUSING HAVING HELICAL SPLINE - A dose setting mechanism for a drug delivery device is disclosed. The mechanism comprises an outer housing and an inner housing having an external groove and a helical spline. The inner housing helical spline guides a driver to dispense a set dose. A dial sleeve is disposed between the outer and inner housing and is rotatably engaged with the inner housing. When a dose is set, the dial sleeve is rotated and translates away from both the outer housing and the inner housing.12-30-2010
20100331806DRIVE MECHANISM FOR A DRUG DELIVERY DEVICE - A dose setting mechanism for a drug delivery device is disclosed. The mechanism comprises an outer housing and an inner housing having an external groove. The inner housing guides a driver having either a blocking or locking member disposed inside the driver that can lock a flexible tab to an internal groove during dose delivery in the inner housing such that the driver follows the path of the groove and to advance a spindle to move a cartridge bung. A dial sleeve is disposed between the outer and inner housing and is rotatably engaged with the inner housing.12-30-2010
20110015576MEDICAMENT IDENTIFICATION SYSTEM FOR MULTI-DOSE INJECTION DEVICES - A dynamic identification system for a multi-dose injection device includes a dose dial sleeve containing indicia of the medicament contained within the device becomes visible or available to the olfactory or gustation senses only during dose setting as the dial sleeve is translated proximally out of the outer housing of the device. A user can readily identify the medicament contained within the device as the dose is being set. A static identifier located on the device that matches the dynamic identifier on the dial sleeve can also be used as a medicament identifier.01-20-2011
