  • Publication number: 20210113374
    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.

  • 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.

  • Publication number: 20190321611
    Abstract: An implantable device for delivering a therapeutic agent to treat an ear of a patient includes a body having a distal end region and a proximal end region. The body defines, at least in part, a reservoir configured to contain the therapeutic agent. The device includes a shaft attached to the distal end region of the body and a lumen extending through the shaft having at least one inlet at a proximal end region in fluid communication with the reservoir and at least one outlet at a distal end region. Upon implantation of the body in a region of the ear, a length of the shaft is sufficient to extend from the body to at least the round window membrane of the ear. The device is configured to deliver the therapeutic agent to the ear from the reservoir via passive diffusion. Related devices and methods are described.
