SUBCONJUCTIVAL IMPLANT FOR POSTERIOR SEGMENT DRUG DELIVERY

摘要

A therapeutic device can be configured to place the reservoir substantially between the conjunctiva and the scleral such that the size of the reservoir can be increased and the size of the scleral penetration decreased so as to decrease invasiveness. The device may comprise a substantially constant reservoir volume and drug release mechanism, in which the volume of the reservoir and mechanism are tuned to receive a quantity of therapeutic agent with a volume of injected formulation and release the therapeutic agent for an extended time with a release rate profile. The porous structure may comprise a first side coupled to the reservoir and a second side to couple to the patient to release the therapeutic agent, and a plurality of interconnecting channels can extend from the first side to the second side.
