  • Publication number: 20230302236
    Abstract: Containment units, dry powder inhalers, delivery systems, and methods for the same are disclosed. Exemplary devices are configured to have inlets and outlets which are formed with the containment walls of a containment unit. Air jets formed by the configuration of inlet(s) and outlet(s) inside the containment unit create significant turbulence and deaggregate the powder. Delivery system components downstream of the containment unit may integrate the exiting aerosol plume with a low flow nasal cannula air stream for delivery to a subject.

  • Patent number: 11534569
    Abstract: Devices, systems, and methods are disclosed which permit ventilation therapy concurrent with humidity and aerosol drug delivery. Exemplary mixer-heaters employ alternating actuation of humidity and drug nebulizers and may use a single constant power setting for the heating section while keeping a controlled outlet temperature over the course of treatment.

  • Patent number: 10010692
    Abstract: A mixer-heater device provides controllable reduction in aerosol droplet size. Additionally, an intermittent delivery mode for administering an aerosol to a patient may take into account patient expiration and reduce aerosol losses without prolonging treatment time. Depositional losses in aerosol delivery systems may be reduced by streamlining the three dimensional geometry of conduits which change stream direction or flow path diameter. Ventilation systems may also benefit from streamlined components, in particular Y-connectors, with resulting advantages such as reduced rebreathed CO2.

  • Publication number: 20180043585
    Abstract: A method of delivering a therapeutic agent comprises providing an aerosol generator that produces an aerosol of particles or droplets containing a therapeutic agent and an excipient for delivery to a first portion of a respiratory tract. The particles or droplets have an initial diameter from about 1 ?m to about 8 ?m, and the initial momentum of the particles or droplets minimizes deposition in the first portion. The particles or droplets are exposed to relative humidity in the respiratory tract by delivering them at a flow rate that defines the residence time in the respiratory tract. The particles or droplets increase in diameter due to hygroscopic growth caused by relative humidity. The aerosol is nasally exhaled so that particles or droplets are delivered to the nasal cavity and deposited in the nasal turbinates or sinus in part because of their increased diameter.

  • Publication number: 20160368181
    Abstract: An assembly and methods for providing a contoured biological tissue are described. The assembly comprises a first plate and a second plate. The first plate is configured to receive a biological tissue. The second plate is configured to apply a compressive force on the biological tissue that is disposed on the first plate. One or both of the first and second plates comprise a defined shape and a contoured area within the defined shape. The contoured area comprises at least first and second elevations and a continuous transition between the first and second transitions. One or more energy sources is associated with one or both of the first and second plates. The one or more energy sources delivers energy while the second plate applies the compressive force on the biological tissue disposed on the first plate.

  • Patent number: 9433588
    Abstract: Pharmaceutically engineered aerosols (e.g. submicrometer and nano-particles and droplets) containing a hygroscopic growth excipient or agent are employed to improve the delivery of respiratory aerosols to the lung. Inclusion of the hygroscopic agent results in near zero depositional loss in the nose-mouth-throat regions and near 100% deposition of the aerosol in the lung. Targeting of the aerosol to specific lung depths is also possible. In addition, methods and apparatuses for delivering aerosols to the lung are provided. The aerosol is delivered to one nostril of a patient while a relatively high humidity gaseous carrier is delivered to the other nostril, resulting in post-nasopharyngeal growth of the aerosol to a size that promotes deposition in the lung.

  • Patent number: 8479728
    Abstract: Methods and devices for inhalation therapy to deliver and embed (deposit) particles less than about 1 ?m in diameter in the lung. High humidity treatment of the lungs causes condensational growth in particle size upon entering the lungs. Increased particle size is conducive to particle embedment (deposition) in deep lung tissue or at a specific targeted lung region.
