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 2):
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 injector comprising a distal port; connecting the distal port of the drug reservoir injector to an input port of a needle assembly, the needle assembly comprising: a needle hub comprising a tubular body, the input port on a proximal end of the needle hub, and a distal stop surface; a needle comprising a proximal end and a distal end, the proximal portion of the needle housed within the tubular body of the needle hub, the distal end of the needle extending distally beyond the needle hub; a slidable shield comprising a cylindrical body, a proximal end, a distal end, and a sidewall, the slidable shield operatively coupled to the needle hub and having a fixed axial dimension; and an external 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 hub between the input port and the distal stop surface 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 hub; loading the drug reservoir 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 hub to move the slidable shield into a second distal position with respect to the needle hub, wherein the proximal end of the slidable shield is distal to the proximal end of the needle hub in both the first, proximal position and the second, distal position.
