  • Publication number: 20200016377
    Abstract: Described here are devices, systems, and methods for treating conditions or diseases of the nose, ear, or throat with an expandable device having a drug coating. The expandable devices may be delivered to a body cavity in a low-profile configuration and expanded to contact surrounding tissue. The expandable devices may deliver or release the drug coating to the tissue. Multiple expansions of a single device may be employed during treatment. Various coating excipients and manufacturing parameters for the expandable devices may also be adjusted to enhance or slow transfer of the drug coating and/or release of the drug to the target tissue site. The drug transferred to the tissue may act as an in situ depot that enables maintenance of a therapeutic level of locally delivered drug for a desired time period after removal of the expandable devices.

  • Patent number: 10299776
    Abstract: A method for maintaining the alignment of the edges of a trocar defect by inserting into a defect a device for compressing the tissue such that part of the device is above while the other is below the defect, then pulling back on the device so that the part below the defect is up against the defect, then while holding the device below the defect in place, push down on the part above the wound so that it compresses the tissue. Finally, release the device from the insertion tool.

  • Patent number: 10166015
    Abstract: A biodegradable device for maintaining the alignment of the edges of a trocar defect, consisting of two bases coupled and offset by a connector. The first base to be positioned below the defect and a second base above. The first base has a threaded hole from its upper surface but not through the lower surface. The connector attached to the bases such that there is a hole aligned with the threaded hole in the first base allowing a device to mate with the threads in the first base. The second base has a hole aligned with the hole in the connector and wide enough to allow a device to mate with the threads in the first base. The device is arranged so the distance between the lower surface of the second base and upper surface of the first base holds the fascia around the trocar defect.

  • Patent number: 9907695
    Abstract: An ophthalmic shunt includes a seal or septum through which multiple injections of the therapeutic agent can be made as needed, thereby avoiding repeated injury to the sclera. The therapeutic agent is temporarily carried in a tube connected to the septum. The therapeutic agent release may be rapid or sustained over a period of time.

  • Publication number: 20170042816
    Abstract: Formulations and methods are disclosed which provide controlled, sustained release of a biologic therapeutic to a space within the body. More specifically, formulations comprising a plurality of hydrophilic polymer strands, and methods of forming and administering such formulations, are disclosed. In some embodiments, the formulations exhibit a burst release, an initial release, a triphasic release, and release over thirty to ninety days of the biologic therapeutic. In some embodiments, the formulations exhibit reversible precipitation of the biologic therapeutic into precipitates having a diameter of about 50 nm to about 10 ?m.

  • Publication number: 20170027724
    Abstract: A polymeric stent can be implanted for treatment of the Eustachian tube. The stent can be designed to have length-dependent radial strength to allow it to stay within the Eustachian tube and to allow normal closing and opening of the Eustachian tube. A balloon can be used to implant the stent, and the balloon can be coated with a therapeutic agent. A coated balloon can also be used to transfer therapeutic agents to the sinus cavity during a balloon sinus dilation procedure.
