  • APPARATUS AND METHODS FOR DRUG DELIVERY USING MICRONEEDLES
    Publication number: 20220280341
    Abstract: A microneedle has a proximal end portion and a distal end portion and defines a lumen. The proximal end portion is configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge. The proximal end portion includes a base surface that is configured to be placed in contact with a surface of a target tissue. The distal end portion of the microneedle includes a beveled surface. The beveled surface defines a tip angle of less than about 20 degrees and a ratio of a bevel height to a bevel width of less than about 2.5.
    Type: Application

  • Apparatus and methods for drug delivery using multiple reservoirs
    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.
