  • Publication number: 20220054405
    Abstract: Described here are systems and methods for delivering an active agent to target tissues of the ear, nose, or throat using a drug delivery platform having the therapeutic drug embedded as part of the drug delivery platform. The drug delivery platform is implanted into a target tissue, and the active agent elutes out of the body of the drug delivery platform for a target period of time, delivering a therapeutic dose of the drug for that period of time. The duration of therapy for an implant into a sinus tissue can be from 3 to 12 months, or longer, thereby providing relief for the full duration of an allergy season. Moreover, the duration of therapy can provide relief to individuals with chronic paranasal sinus condition symptoms for a period of time longer than presently available therapies, thus allowing for only semi-annual or annual applications of the therapy.

  • Publication number: 20180154051
    Abstract: The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.

  • Publication number: 20180146530
    Abstract: A safety lamp includes a light sensing unit, a first driving unit, a motion sensing unit, a second driving unit, a time setting unit, and a light-emitting unit. The first driving unit outputs a low-current power and the second driving unit outputs a high-current power. The motion sensing unit senses a movement of an object and output a sensing signal. The time setting unit counts the number of lighting times of the light-emitting unit. The light-emitting unit is driven by the low-current power when the light sensing unit is turned on; the light-emitting unit is driven by the low-current power and the high-current power when the motion sensing unit is turned on; when the number of lighting times is completed, the time setting unit disconnects the high-current power outputted from the second driving unit to the light emitting unit.
