  • Patent number: 11058856
    Abstract: An apparatus includes a housing and a pushrod. The housing defines a delivery passage and an exit port in fluid communication with the delivery passage. At least a portion of the pushrod is movably disposed in the delivery passage. A distal end portion of the pushrod is configured to move a drug dosage form through at least a portion of the delivery passage to convey the drug dosage form through the exit port when the distal end portion of the pushrod is moved from a first position to a second position. A surface of at least one of the pushrod or the housing defining the delivery passage is nonplanar, curved and/or contoured.

  • Publication number: 20180243169
    Abstract: Single dose drug dosage form dispensing devices, and methods for operating such devices are disclosed herein. In one embodiment, an apparatus includes a housing defining an actuation pathway and a pusher. At least a portion of the pusher is disposed within the actuation pathway such that a distal end portion of the pusher and a distal end portion of the housing define a volume configured to contain a drug-containing tablet. The pusher is configured to move relative to the housing in a distal direction from a first position to a second position to expel the drug-containing tablet from the volume. The distal end portion of the pusher is extended from an opening in the housing when the pusher is in its second position. The housing is configured to limit movement of the pusher relative to the housing in a proximal direction from the second position of the pusher towards the first position of the pusher after the drug-containing tablet is expelled from the volume.

  • Patent number: 8499966
    Abstract: A method of administering small, bioadhesive drug tablets includes moving an end portion of a delivery member. A surface of the delivery member can be positioned to prevent movement of the drug tablet from a tablet cartridge channel to a delivery passage of a delivery device when the end portion of the delivery member is in a first stopped position. The end portion of the delivery member can be moved to a second position within the delivery passage such that the tablet cartridge channel is in communication with the delivery passage. The drug tablet can be conveyed into the delivery passage via the tablet cartridge channel. The end portion of the delivery member can be moved to a third position within the delivery passage to convey the drug tablet through an exit opening of the delivery device.
