Abstract: A medication delivery device usable with a medication container wherein advancement of a piston within the container expels medication. The device includes a housing and a drive assembly. The drive assembly includes a drive ribbon having distal and proximal edge sections. The drive ribbon has a retracted configuration defining a spiral and an extended configuration defining a helix. The drive ribbon is movable from the retracted configuration to the extended configuration with the movement defining a drive axis and advancing the piston. In some embodiments, the drive ribbon may not rotate as the drive ribbon is advanced while in other embodiments, the ribbon does rotate. Disclosed drive assemblies include manually driven assemblies, spring driven assemblies and motor driven assemblies. The container may be replaceable to allow for reuse of the device. In some embodiments, replaceable cartridges which include both the medication container and the drive ribbon are employed.

Abstract: A medical delivery device for advancing a piston in a medicament container to expel a medicament. A support structure supports the container and a drive assembly that advances the piston. The drive assembly includes a drive ribbon that can be retracted and extended. The retracted ribbon defines a spiral and the extended ribbon defines a helix. The drive ribbon is incrementally moveable between the retracted spiral configuration and extended helical configuration. A mechanical drive rotates the drive ribbon to selectively extend and retract the ribbon. A thrust member having a helical ramp engages a proximal edge of the drive ribbon where it transitions between a spiral and helix. A bearing member at the distal end of the drive ribbon exerts an axial force on the piston when the ribbon is extended.

Abstract: A method and apparatus for imaging an object including the steps of projecting radiation from a radiation source through an object and moving the radiation source through multiple imaging positions relative to the object without stopping movement of the radiation source. Movement is accomplished while projecting radiation at more than one of the imagining positions with the source having a source velocity for at least one imaging position that is different from a source velocity for a second imaging position. Radiation transmitted through the object is also detected. Radiation may be projected while moving the radiation source through the multiple imaging positions. In addition, the velocity at which the radiation source is moved through a select imaging position may be related to a resolution desired for data collection at the select imaging position. The velocity of the radiation source may be varied within a select imaging position.

Abstract: A dose indicating assembly in a pharmaceutical injection device (20). The dose indicating assembly includes an external housing barrel (31) extending in an axial direction, and a dial at least partially disposed within the housing barrel. The dial (33) is screwably movable in the axial direction relative to the barrel during dose setting. The dial includes an outer radial periphery with a plurality of parallel arrays (38, 39, 40) of dose indicia provided thereon, each of the plurality of arrays of dose indicia provided in a helical pattern on the periphery. The dose indicating assembly also includes means (50) for viewing the dose indicia of a selectively chosen one of the plurality of arrays.
