  • Publication number: 20190054236
    Abstract: Some embodiments of an infusion pump assembly may be equipped with one or more components to facilitate wireless operation of an infusion pump via a user-operated mobile device. In some embodiments, the mobile device and/or the infusion pump may prompt the user to confirm acceptance of a wirelessly communicated command to prevent an operation by the infusion pump (e.g., a dispensation of medicine) that is not desired by the user.

  • Publication number: 20180161494
    Abstract: Some embodiments of an infusion pump system include a pump device with a drive system that is configured to attach with a medicine cartridge in manner that reduces the likelihood of dosage inaccuracies. In one example, the drive system of the pump device can be equipped with a plunger engagement device that is configured to mechanically anchor into a plunger of the medicine cartridge, and then to bias the plunger of the medicine cartridge in a direction toward a piston rod of the drive system.

  • Patent number: 9956339
    Abstract: Some embodiments of an infusion pump system may be configured to provide a desired level of resistance to liquid ingress to the pump casing while contemporaneously providing air transmissibility for equalization of air pressure differentials between the interior and exterior of the pump casing. Further, some embodiments can detect when moisture inside a casing of the infusion pump system is greater than or equal to a threshold level and can initiate one or more patient safety countermeasures.

  • Publication number: 20180085522
    Abstract: Some embodiments of an infusion pump system can include a controller in which one or more features sets to be provided by the controller are enabled or disabled based upon the particular pump device that is connected to the controller. For example, in some embodiments, one or more advanced features of the controller are available to the user only when a first type of pump device (e.g., having predefined settings stored therein) is connected to the controller, and those advanced features of the controller are disabled when a second type of pump device is connected to the controller.

  • Patent number: 9545476
    Abstract: Some embodiments of an infusion pump system may be configured to detect when at least one component of the pump system is exposed to an impact above a threshold level. In particular embodiments, the infusion pump system can be equipped with an impact detection system that can sense when an impact above the threshold level has occurred to the pump device, which thereby enables the infusion pump system to initiate appropriate patient safety countermeasures.

  • Publication number: 20150327837
    Abstract: A method of navigating and positioning an endovascular device in a vasculature is disclosed. Initially, a system including an endovascular device and at least one transducer is inserted into the lumen of a patient. An acoustic signal is then transmitted within the lumen. A reflected signal is pre-processed to extract one or more acoustic features. The one or more acoustic features are processed using a computer readable set of rules to produce an output related to guidance of the instrument within a blood vessel or a position of the instrument within the blood vessel.
