  • Patent number: 8986250
    Abstract: A drug delivery platform is provided for delivering a controlled infusion of a drug to an individual. The drug delivery platform includes a reservoir for receiving the drug therein and a pressure source engageable with the reservoir. The pressure source is movable between a first configuration and a second configuration wherein the pressure source exerts a pressure on the reservoir to urge the drug therefrom. An output conduit is provided for transmitting the drug into the individual. An actuation mechanism is operatively connected to the pressure source and the output conduit. The actuation mechanism is movable between a non-actuated position and an actuated position wherein pressure source moves from the first configuration to the second configuration and wherein the input of the output conduit communicates with the drug and the output end of the output conduit is receivable in the individual.

  • Patent number: 8795259
    Abstract: A drug delivery platform is provided for delivering a controlled infusion of a drug to an individual. The drug delivery platform includes a reservoir for receiving the drug therein and a hydrogel engageable with the reservoir. The hydrogel is movable between a first configuration and a second configuration wherein the hydrogel exerts a pressure on the reservoir to urge the drug therefrom in response to a predetermined stimulus. A flow guide distributes the predetermined stimulus over the hydrogel in response to activation by an individual.

  • Publication number: 20110172638
    Abstract: An apparatus for delivering a drug to a subject is provided. The apparatus includes a housing, a microneedle coupled to the housing and configured to extend from the housing when activated, an activation control coupled to the housing and an outer shell. The outer shell includes a top wall having an inner surface and a sidewall extending from the top wall, the sidewall having an inner surface. The outer shell includes a first attachment structure configured to attach to the housing. The outer shell covers the activation control when the first attachment structure is attached to the housing. The outer shell includes a second attachment structure configured to attach to the housing. The outer shell covers the activated microneedle when the second attachment structure is attached to the housing.

  • Publication number: 20110172637
    Abstract: A drug delivery device for delivering a drug to a subject includes a microneedle configured to facilitate delivery of the drug to the subject. The microneedle includes a tip portion and is moveable from an inactive position to an activated position. When the microneedle is moved to the activated position, the tip portion of the microneedle is configured to penetrate the skin of the subject. The drug delivery device includes a tissue support structure that includes a channel and an engagement element. The channel has a first end and a second end and is in axial alignment with the microneedle. At least the tip portion of the microneedle extends past the second end of the channel in the activated position.

  • Publication number: 20080038130
    Abstract: A medical pump includes a chassis having a fixed seat, and a main carriage having a carriage footing for receiving a fluid delivery device and restricting its movement. An actuator automatically moves the main carriage between open and closed positions to engage the fluid delivery device to the seat. The seat establishes the position of both the main carriage and fluid delivery device in the closed position. The actuator is connected to the main carriage by a rear carriage assembly having a manual release element for disengaging the actuator from rear carriage assembly and thereby from the main carriage. A processing unit detects jam conditions by processing carriage position data and electrical load data from the actuator.
