    Abstract: A system and method can provide for a remote electronic device to be used to remotely initiate delivery of a medicament bolus with a medical device, such as an insulin pump, with the medical device providing audible or tactile confirmation of the programmed bolus. The bolus amount can be calculated by or programmed or otherwise entered into the smartphone, etc., and then transmitted to the medical device. When the pump receives the transmitted bolus amount, it issues one or more indications such as audible sounds and/or vibrations in any number of desired combinations. For instance, each individual sound or vibration may correspond to an increment of the medicament. The user can therefore determine the size of the medicament bolus by the number of sounds or vibrations and can confirm or cancel delivery of the bolus.

  • Patent number: 9358336
    Abstract: Drug delivery device with electronically controlled and axially displaceable piston drive member (10) adapted to engage a loaded cartridge piston. The piston drive member is moveable between a proximal loading position in which a cartridge can be received and a distal loaded position in engagement with the piston. A proximity sensor (11,12) provides a varying output indicative of a varying distance between the piston drive member and the piston. A controller (30) coupled to the proximity sensor is configured to control movement of the piston drive member from the loading position to the loaded position and stop movement when the controller based on input from the proximity sensor system determines that the loaded position has just been reached. By this arrangement it is prevented that a drug-filled cartridge is pressurized during the loading and initializing procedure.

  • Patent number: 9248241
    Abstract: In certain embodiments, a syringe mount of the invention may include a plate, an actuator, and one or more movable members located between the plate and the actuator. Each of the plate and the actuator may have an orifice defined therein, and an imaginary reference axis of the syringe mount may extend through one or both of these orifices. The actuator may be movable relative to the plate in a direction substantially perpendicular to the reference axis. Further, the moveable member(s) may be designed to move (e.g., pivot) toward the reference axis due to movement of the actuator from a first position to a second position and to move (e.g., pivot) away from the reference axis due to movement of the actuator from the second position to the first position.

  • Patent number: 9180252
    Abstract: A bellows assembly for a fluid delivery system is a multi-component device that includes a cylindrical pressure jacket and a bellows syringe that is received within the pressure jacket. The bellows syringe includes a cap member and a bellows member. The bellows syringe in one embodiment is adapted to be secured to the pressure jacket by the cap member. The cap member is formed with a discharge port, which may be formed as conventional luer fitting. The discharge port is disposed coaxially within an annular wall on the outward facing side of the cap member and may be recessed within the annular wall. The bellows member is a hollow body that includes a series of bellows sections or rings. A distal end of the bellow member is formed with a discharge neck terminating in a discharge port, and the proximal end is formed with a closed end wall.

  • Patent number: 9063552
    Abstract: An electronic controller module for controlling outward movement of the piston comprises an input/output port and a processor module. The processor module determines a prescribed movement speed and sends a motor command via the port at an initial motor speed. The motor causes the outward movement. The port receives speed measurements. The processor module attempts to match the measurements to a prescribed speed by sending successive motor commands via the port.

  • Publication number: 20150148779
    Abstract: Apparatus for delivering material into a patient includes a catheter having a proximal end and a distal end. Material, preferably of filamentary or thread form, is fed from a material supply into a Y-fitting having a main branch and a side branch. The side branch is connected to a source of driving fluid able to feed drive fluid under pressure into the material carrier so as to pull material forwardly and out of the distal end of the catheter. The assembly includes an inner cannula within which material is passed from the material source. This increases the speed of delivery of material though the device and reduces the amount of drive fluid which is required.
