1. A system for injecting a therapeutic agent into an ocular implant, the ocular implant being at least partially implanted in an eye, the system comprising:
a cartridge configured to couple to a syringe; and
a needle coupled to the cartridge defining an injection lumen and an outlet lumen fixed relative to one another, wherein the injection lumen is longer than the outlet lumen such that an opening from the injection lumen is positioned distal to an opening into the outlet lumen,
wherein application of positive pressure into the injection lumen injects a therapeutic agent into an ocular implant through the injection lumen and displaces pre-existing fluid in the ocular implant through the outlet lumen into the cartridge, and
wherein the outlet lumen includes a restriction structure configured to resist flow into the outlet lumen such that a portion of the therapeutic agent injected through the injection lumen passes as a bolus through the ocular implant and into the eye.
