Claim:
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: an injection lumen configured to provide a pathway for injecting a therapeutic agent into the ocular implant, the injection lumen having an outlet opening for therapeutic agent to flow out of the injection lumen into the implant; an outlet lumen configured to provide a pathway through which pre-existing fluid in the ocular implant exits the ocular implant as therapeutic agent is injected into the ocular implant through the injection lumen, wherein the outlet lumen surrounds at least a portion of the injection lumen, the outlet lumen having an inlet opening for fluid to exit into the outlet lumen from the ocular implant; a receiver chamber fluidly coupled to the outlet lumen, the receiver chamber configured to receive fluid that exits the ocular implant via the outlet lumen; wherein injection of the therapeutic agent into the ocular implant via the injection lumen displaces pre-existing fluid in the ocular implant into the receiver chamber via the outlet lumen, and wherein the injection lumen is in a fixed position relative to the outlet lumen.
