    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.

    摘要： An injectable formulation of therapeutic agent may comprise the therapeutic agent and a stabilizer such that a substantial portion of the stabilizer remains in the therapeutic device to stabilize the therapeutic agent when the therapeutic agent is released from the therapeutic device. The injectable formulation may comprise one or more of binding agent particles or erodible material particles, such that the formulation can be injected into the therapeutic device. The binding agent particles can bind reversibly to the therapeutic agent so as to modulate release of the therapeutic agent, and the erodible material particles can generate protons of an acid so as to increase stability of the therapeutic agent and may modulate release of the therapeutic agent. The therapeutic agent can be combined with one or more of the stabilizer, the binding agent particles or the erodible particles to increase stability of the therapeutic agent and may modulate release.

    摘要翻译： 治疗剂的可注射制剂可以包含治疗剂和稳定剂，使得当治疗剂从治疗装置释放时，大部分稳定剂保留在治疗装置中以稳定治疗剂。 可注射制剂可以包含一种或多种粘合剂颗粒或可侵蚀材料颗粒，使得可以将制剂注射到治疗装置中。 结合剂颗粒可以可逆地结合治疗剂以调节治疗剂的释放，并且可侵蚀的材料颗粒可以产生酸的质子，以增加治疗剂的稳定性并且可以调节治疗剂的释放。 治疗剂可以与稳定剂，结合剂颗粒或可侵蚀颗粒中的一种或多种组合以增加治疗剂的稳定性并且可以调节释放。

    摘要： A therapeutic device to release a therapeutic agent comprises a porous structure coupled to a container comprising a reservoir. The reservoir comprises a volume sized to release therapeutic amounts of the therapeutic agent for an extended time when coupled to the porous structure and implanted in the patient. 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. A plurality of interconnecting channels can extend from the first side to the second side so as to connect a first a plurality of openings on the first side with a second plurality of openings on the second side. Each of the openings on the first side can be connected to each of the openings on the second side with the plurality of interconnecting channels, such that the rate of release of the therapeutic agent can be substantially maintained when one or more of the openings is blocked, for example with particles, cells, bacteria or tissue when the device is implanted for an extended time. The length of the channels extending from the first side to the second side may comprise an effective length greater than a distance across the porous structure from the first side to the second side. The therapeutic device many comprise an expandable retention structure and an expandable reservoir, such that the device can be delivered from a lumen of a delivery device and expand when positioned in the patient. The therapeutic device may comprises a penetrable barrier to inject therapeutic agent into the device when implanted in the patient.
