  • Publication number: 20230338282
    Abstract: 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.

  • Patent number: 11786396
    Abstract: Methods and apparatus provide a therapeutic fluid to devices implanted in the body, for example to containers of devices implanted in the eye of a patient. The methods and apparatus may comprise an injector to increase an amount of therapeutic agent injected into the device implanted in the eye, or a structure to receive the therapeutic fluid within the device implanted in the eye, or combinations thereof. The device implanted in the eye may comprise a reservoir chamber having a fluid with a density different than the therapeutic fluid, and the apparatus can be adapted to at least partially separate the implanted device fluid from therapeutic fluid within the reservoir chamber to increase and amount of therapeutic fluid placed in the reservoir chamber.

  • Patent number: 11679027
    Abstract: Methods and apparatus provide treatment with a first therapeutic agent and a second therapeutic agent for an extended time. The first therapeutic agent may comprise a VEGF inhibitor and the second therapeutic agent may comprise an antiinflammatory, such as a non-steroidal anti-inflammatory, for example a cyclooxygenase inhibitor. One or more of the first therapeutic agent or the second therapeutic agent can be injected into the eye, for example injected into a therapeutic device implanted into the eye to release the injected therapeutic agent for an extended time.

  • Publication number: 20230102547
    Abstract: A therapeutic system comprises an ocular insert placed on a region outside an optical zone of an eye. The ocular insert comprises two structures: a first skeletal structure and a second cushioning structure. The first structure functions as a skeletal frame which maintains positioning of the implant along the anterior portion of the eye and provides support to the second, cushioning structure. This first structure maintains the attachment of the therapeutic system to the anterior portion of the eye for at least thirty days. In some embodiments the first structure remains a constant size and shape, e.g. a ring shape, a ring with haptics, or a curvilinear ring that is confined to and restrainingly engages the inferior and superior conjunctival fornices so as to retain the implant within the tear fluid and/or against the tissues of the eye.

  • Patent number: 11065151
    Abstract: 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.

  • Publication number: 20210096397
    Abstract: A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10-4 Pa*m3 to about 5×10-4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

  • Patent number: 10835416
    Abstract: A comfortable insert comprises a retention structure sized for placement under the eyelids and along at least a portion of conjunctival sac of the upper and lower lids of the eye. The retention structure resists deflection when placed in the conjunctival sac of the eye and to guide the insert along the sac when the eye moves. The retention structure can be configured in many ways to provide the resistance to deflection and may comprise a hoop strength so as to urge the retention structure outward and inhibit movement of the retention structure toward the cornea. The insert may move rotationally with deflection along the conjunctival sac, and may comprise a retention structure having a cross sectional dimension sized to fit within folds of the conjunctiva. The insert may comprise a release mechanism and therapeutic agent to release therapeutic amounts of the therapeutic agent for an extended time.

  • Patent number: 10653554
    Abstract: An injector apparatus comprises an elongate structure having one or more openings positionable near a penetrable barrier of an implantable device so as to receive fluid of the implantable device. The apparatus comprises a needle and a sheath extending over at least a portion of the needle. The elongate structure may comprise a distal tip to penetrate tissue and the penetrable barrier, and a distal opening near the tip to release therapeutic fluid into the implantable chamber. In many embodiments the distal tip, the distal opening, and the plurality of openings are separated from a stop that engages a tissue of the patient and limit penetration depth such that the distal opening and the plurality of openings are located along an axis of the implantable device to increase an efficiency of the exchange.
