  • Patent number: 12201558
    Abstract: An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

  • Patent number: 11142634
    Abstract: This disclosure relates to a continuous solution polymerization process wherein production rate is increased. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst formulation are injected into a first reactor forming a first ethylene interpolymer. Process solvent, ethylene, optional comonomers, optional hydrogen and a heterogeneous catalyst formulation are injected into a second reactor forming a second ethylene interpolymer. The first and second reactors may be configured in series or parallel modes of operation. Optionally, a third ethylene interpolymer is formed in an optional third reactor, wherein an optional heterogeneous catalyst formulation may be employed. In a solution phase, the first, second and optional third ethylene interpolymers are combined, the catalyst is deactivated, the solution is passivated and following a phase separation process an ethylene interpolymer product is recovered.

  • Patent number: 10188550
    Abstract: A cartridge, including a first member that defines an inner volume and a second member disposed therein, is disposed in a housing. A first reservoir is disposed in the inner volume in a position distal to the second member. The first member is partially disposed in a second reservoir, defined by the housing. The second member is configured to be moved from a first position, in which the first reservoir contains a drug and the second reservoir is fluidically isolated from the inner volume, toward a second position, in which the first reservoir and the second reservoir are in fluid communication with the inner volume, such that the second reservoir receives a volume of the drug from the first reservoir. The first member and the second member are collectively moved relative to the second reservoir to expel the volume of the drug from the second reservoir.

  • Patent number: 10039691
    Abstract: A method of providing airway clearance therapy to a patient includes receiving an expiratory airstream from the patient in a chamber, causing a back pressure to be created in the chamber (10) in response to receiving the expiratory airstream, causing a one-way valve, such as a magnetic duckbill valve (26), located downstream of the chamber to open only in response to the back pressure being at least equal to a certain predetermined level, causing a vibratory effect to be generated downstream of the one-way valve, for example using a vibratory ball check valve (32), when the one-way valve is open and in response to the expiratory air-stream passing therethrough, and delivering a percussive sensation to the patient through the chamber responsive to the vibratory effect.
