Claim 18:
19. A device for removing a protective shield from a drug delivery system having a medicament container, an injection needle in communication with the medicament container, a protective shield disposed about said injection needle, the device comprising:
a puller body having a sidewall that circumscribes an interior space about a longitudinal axis, a distal bottom wall interconnected to the sidewall, and a proximal end opening in communication with the interior space, the interior space configured to receive the protective shield through the proximal end opening, wherein the sidewall defines sidewall openings therein;
a plurality of resilient fingers, each resilient finger of the plurality of resilient fingers disposed in a corresponding sidewall opening of the sidewall openings defined in the sidewall and located surrounding the interior space, each resilient finger of the plurality of the resilient fingers having a finger proximal end flexibly coupled with the sidewall and extending distally toward the distal bottom wall to a finger distal end; and
each resilient finger of the plurality of resilient fingers further including a plurality of projections axially arranged and extending toward the interior space and engageable with the protective shield in a manner to facilitate removal of the protective shield during removal of said device, each projection of the plurality of projections having a proximal surface and a distal surface, wherein the distal surface of a distalmost projection of the plurality of projections of each respective resilient finger defines a distal engagement surface, the distal engagement surface extends farther radially outward than the distal surface of at least one of the other projections of the plurality of projections.
