Abstract:
Injection devices for delivering pharmaceutical compositions into the eye are described. Some devices include a resistance component for controllably deploying an injection needle through the eye wall. The resistance component may be disposed on a removable injector attachment or on a portion of the injection device housing. Other devices may include a filter for the removal of air, infectious agents, and/or other particulate matter from the composition before the composition is injected into the eye. Related methods and systems comprising the devices are also described.

Claim (Index 21):
A method of more safely loading a drug from a vial into a drug reservoir, comprising:\n providing a drug vial comprising a stopper and a drug within the vial; providing a drug reservoir comprising a distal port; connecting the distal port of the drug reservoir to an input port of a needle assembly, the needle assembly comprising: a tubular body, the input port on a proximal end of the needle assembly; a needle comprising a proximal end and a distal end, the proximal portion of the needle housed within the tubular body of the needle assembly, the distal end of the needle extending distally beyond the needle assembly; a slidable shield comprising a cylindrical body, a proximal end, a distal end, and a sidewall, the slidable shield operatively coupled to the needle assembly and having a fixed axial dimension; and a resistance component comprising a locking mechanism; advancing the distal end of the needle through the stopper of the vial such that the slidable shield axially moves along the needle assembly until the needle tip penetrates through the vial stopper to access the vial cavity such that the slidable shield is in a first, proximal position with respect to the needle assembly; loading the drug reservoir injector with the drug from the vial through the needle assembly; and withdrawing the needle assembly from the drug vial, wherein the slidable shield moves axially distally such that the needle is completely circumscribed by the slidable shield or the distal end of the needle assembly to move the slidable shield into a second distal position with respect to the needle assembly, wherein the proximal end of the slidable shield is distal to a distal end of the drug reservoir in both the first, proximal position and the second, distal position.
