| 20100324527 | DRUG DELIVERY DOSE SETTING MECHANISM WITH VARIABLE MAXIMUM DOSE - A method and system for proving a drug delivery device having a variable dose. The drug delivery device comprising a first tubular member and a second tubular member rotatably coupled to the first tubular member. A maximum stop component is operatively coupled to the first and second tubular member such that the maximum stop component is movable from a first position to a second position. The first position defines a first maximum dose that may be set by a user of said drug delivery device and the second position defines a second maximum dose that may be set by the user of said drug delivery device. | 12-23-2010 |
| 20100324528 | DOSE SETTING MECHANISM FOR PRIMING A DRUG DELIVERY DEVICE - A method and system for priming a drug delivery device. The drug delivery device includes a dose dial sleeve and an internal housing portion. The dose dial sleeve is coupled to the internal housing. The dose dial sleeve rotates on a substantially circumferential rotational path during priming of the drug delivery device. Further, the dose dial sleeve rotates on a helical path during dose setting of the drug delivery device. | 12-23-2010 |
| 20110152784 | PEN-TYPE INJECTOR - The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose-cartridge and permit a user to set the delivery dose. The injector may include a housing, a piston rod adapted to operate through the housing, a dose dial sleeve located between the housing and the piston rod, and a drive sleeve located between the dose dial sleeve and the piston rod. The dose dial sleeve may have a helical thread of first lead and the drive sleeve may have a helical groove of second lead. The first lead of the helical thread and the second lead of the helical groove may be the same. | 06-23-2011 |
| 20110178474 | DRIVE MECHANISMS SUITABLE FOR USE IN DRUG DELIVERY DEVICES - A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device. | 07-21-2011 |

| 20120010575 | DRIVE ASSEMBLY SUITABLE FOR USE IN A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE - A drive assembly for use in a drug delivery device is proposed, the drive assembly comprising: a housing having a proximal end and a distal end; an axis extending between the proximal end and the distal end; at least one drive member; a piston rod adapted to be driven along the axis by the drive member; an indicator adapted to provide positional information about a position of the piston rod relative to the proximal end, wherein the indicator and the piston rod are configured to convert a movement of the piston rod with respect to the housing into a rotational movement of the indicator. Additionally, a drug delivery device comprising the drive assembly is provided for. | 01-12-2012 |
