Claim Text:
1. A delivery device comprising: a first housing portion; a second housing portion configured to selectively engage with and disengage from the first housing portion; a rotatable member supporting a grouping of coupled projections for movement in an annular path with the rotation of the rotatable member; a resilient member supported by the first housing portion and having a flexible portion and arranged within at least a portion of the annular path of the grouping of coupled projections to be engaged at a single location along the annular path, in turn, by the grouping of coupled projections when the second housing portion and the first housing portion are engaged, the flexible portion of the resilient member being resiliently collapsible at the single location of engagement of the grouping of coupled projections to provide an intermittent pulse of force at the single location as the rotatable member rotates the grouping of coupled projections along the annular path while the second housing portion and first housing portion are engaged, the resilient member being connectable in fluid flow communication with an injection site, wherein the flexible portion of the resilient member is supported on a flat support surface; a reservoir having an interior volume for containing a fluid, the interior volume of the reservoir being in fluid flow communication with the resilient member; and a motor supported by the second housing portion and operatively coupled to the rotatable member for selectively rotating the rotatable member.
