  • Patent number: 11672960
    Abstract: Described here are systems, devices, and methods for delivery of an implant to a bodily cavity. The implant may include a hub and a plurality of legs, and may be moveable between a low-profile and expanded configuration. The systems may include a crimping device having a crimping member with a plurality of arms. The plurality of arms may engage the plurality of legs of the implant, and may move the legs to move the implant to the low-profile configuration. In some instances a delivery device may aid in crimping and/or delivery of the implant.

  • Patent number: 11672959
    Abstract: Described here are systems and methods for delivering an active agent to target tissues of the ear, nose, or throat using an expandable member having drug crystals layered thereon, and methods for manufacturing such systems. The expandable member can be delivered to the target tissues in a low-profile configuration and expanded to contact and/or dilate surrounding tissue. Expansion of the expandable member transfers the drug crystals to the target tissues, which then act as an in situ depot that enables maintenance of a therapeutic level of an active agent for a desired time period after removal of the expandable member. Multiple expansions of a single expandable member can be employed during treatment. For example, the systems and methods can be useful when it is desired to treat multiple paranasal sinuses with a single expandable member.

  • Patent number: 11291812
    Abstract: The invention provides biodegradable implants for treating sinusitis. The biodegradable implants have a size, shape, density, viscosity, and/or mucoadhesiveness that prevents them from being substantially cleared by the mucociliary lining of the sinuses during the intended treatment period. The biodegradable implants include a sustained release therapeutic, e.g., an antibiotic, a steroidal anti-inflammatory agent, or both. The biodegradable implants may take various forms, such as rods, pellets, beads, strips, or microparticles, and may be delivered into a sinus in various pharmaceutically acceptable carriers.

  • Patent number: 10814108
    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: 10688289
    Abstract: This application is generally related to systems and methods for accessing the paranasal sinuses and other passages of the nose, ear, and throat. The systems and methods generally employ devices capable of maintaining a fixed handle orientation with respect to the patient while generating the appropriate applicator deflection angle required to rotationally align or orient the applicator tip to the intended target tissue/anatomy for treatment. Methods are also described for deploying drug delivery devices within these body structures using the systems to treat medical conditions associated therewith.
