  • Patent number: 10478551
    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.

    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.

  • Publication number: 20150141911
    Abstract: The invention is about a next-generation blood pump that provides pulsatile blood flow, and has been developed for cardiopulmonary by-pass devices used for maintaining extracorporeal blood circulation during heart surgeries and the supportive devices of circulation system. This device is technically a sort of synchronous power-assisted motor employing direct driver technology. The mentioned blood pump contains a rotor rotating on a magnetic bearing without a shaft and through the helical wings placed into the rotor it provides pulsatile blood supply adequate for the body requirement synchronous with the ECG signals received from the patients. It provides a patient safer and controlled pulsatile blood flow while running at high efficiency.

  • Publication number: 20150045735
    Abstract: Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

  • Patent number: 8915399
    Abstract: A medical fluid injection system may include a powered injector and a fluid reservoir that contains a simulated contrast medium. The simulated contrast medium may exhibit a fluid flow property substantially equal to that of an active contrast medium but be devoid of any active contrast agent that provides contrast during diagnostic imaging. During operation, a syringe in the powered injector may be filled with the simulated contrast medium and then evacuated to discharge the simulated contrast medium from the syringe. The simulated contrast medium may be used to test and evaluate the performance of the powered injector prior to use in a medical procedure without exposing personnel to an active contrast agent or creating medical waste that contains the active contrast agent.
