  • Publication number: 20190167897
    Abstract: Systems and methods are provided for signaling a condition of an infusion assembly. A system may comprise an elastomeric pump that includes a chamber for receipt of a volume of fluid, an outer layer configured to expand and contract as the chamber receives and dispenses fluid, and a passive indicator provided on the outer layer for signaling a change in the volume of fluid in the chamber. The system further may comprise an image capture device configured to capture an image of the pump, and a processing system configured to process the image to signal the condition of the infusion assembly to a user of the system. A method may comprise capturing an image of a pump; processing the image; and displaying information to a user of the pump to communicate the condition of the pump to the user. Elastomeric pumps for infusion assemblies also are provided.

  • Publication number: 20190159753
    Abstract: The present invention is directed to an ultrasound imaging system having a motor-assisted needle guide assembly for easier needle placement during an ultrasound-guided medical procedure. The ultrasound imaging system includes an ultrasound probe having a transducer housing, a transducer transmitter, a needle guide assembly communicatively coupled to the ultrasound probe, at least one actuator component configured with the needle guide assembly, and a controller. Thus, the controller is configured to determine an insertion angle and a lateral position for the needle guide assembly with respect to the ultrasound probe based on the target site and control the actuator component based on the insertion angle and the lateral position so as to locate the needle guide assembly at the target site during a medical procedure.

  • Publication number: 20190001054
    Abstract: An elastomeric pump having at least one sensor for sensing changes in elongation of a bladder of the pump is provided. Also provided is an infusion assembly including an elastomeric pump having a bladder, at least one sensor for sensing changes in elongation of the bladder, and an indicator for providing one or more outputs of the sensor. The sensor may be a flexible sensor positioned in contact with the bladder of the pump, or a dielectric material may be incorporated into the material the bladder is made from such that the dielectric elastomer material of the bladder forms the sensor.

  • Publication number: 20180322943
    Abstract: Methods and systems for managing patient health data are provided. A patient data tracking system is provided that aggregates patient data to create one or more patient data sets. The system analyzes and/or sorts the patient data set(s) to selectively provide information to different entities. The patient data may be secured such that the patient data set(s) are stored and/or disseminated in compliance with one or more applicable governmental or organizational regulations. As one example, the system can provide targeted information to a physician and healthcare organization that can help the physician and healthcare organization direct a patient's pain management therapy, develop treatment protocols for a patient population, or the like. The platform may use one or more dashboards to disseminate targeted information to the different entities. The dashboards may present information regarding an individual patient or one or more patient populations, e.g., aggregate patient population data or trends.

  • Publication number: 20180310914
    Abstract: The present disclosure is directed to an ultrasound imaging system for generating 3D images. The system includes an ultrasound probe having a transducer housing and a transducer transmitter. The housing has a body extending from a proximal end to a distal end along a longitudinal axis. The distal end includes an internal cavity that extends, at least, from a first side to a second side along a lateral axis of the housing. The transmitter is mounted to the first and second sides within the cavity and is configured to rotate about the lateral axis for scanning of an ultrasound beam. Thus, during operation, the transmitter is free to rotate in a clockwise direction and/or a counter-clockwise direction about the lateral axis so as to continuously scan two-dimensional (2D) images. The system may also include a controller configured to receive and organize the 2D images in real-time and generate a 3D image based on the 2D images.

  • Publication number: 20180280608
    Abstract: A system for delivering fluid to a user transcutaneously includes a subcutaneous infusion cannula base assembly, a cannula inserter assembly and a fluid connection assembly. The subcutaneous infusion cannula base assembly is configured to be located on the user's skin. The cannula inserter assembly is coupled to the cannula base assembly and is configured to drive an infusion cannula through the user's skin in a nominally helical trajectory. The fluid connection assembly is configured to fluidically connect the cannula base assembly to a source of delivery fluid. Cannula and stylet assemblies configured for helical or non-helical insertion are also disclosed.

  • Publication number: 20180280053
    Abstract: The present disclosure is directed to an ultrasound imaging system with an integrated needle advancer. More specifically, the ultrasound imaging system includes an ultrasound probe having a transducer housing, a transducer transmitter, a needle assembly, and a controller. The transducer housing has a body that defines an internal cavity. The internal cavity includes a passageway extending from a proximal end to a distal end of the body. The needle assembly is configured within the passageway of the internal cavity. The transducer transmitter is configured within the distal end of the body. Further, the transducer transmitter is configured to emit and receive ultrasound beams. Thus, the controller is configured to generate an image from the ultrasound beams.

  • Publication number: 20180207356
    Abstract: A continuous subcutaneous infusion catheter includes an elongate flexible cannula and a plurality of holes through the cannula wall that are positioned both along the axial length of the cannula and radially around the cannula. The proximal end of the cannula is configured to be attached to a pump, and the distal end of the flexible cannula is atraumatic. The catheter can be used to deliver insulin to a patient.

  • Publication number: 20180199915
    Abstract: The present disclosure is directed to an ultrasonic catheter assembly. More specifically, the catheter assembly includes a catheter and one or more piezoelectric or echogenic components. The catheter has a side wall that extends from a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the lumen is configured to deliver a treatment fluid from the proximal end to the distal end. In addition, the piezoelectric component(s) are configured with the side wall of the catheter and/or embedded at least partially within the side wall of the catheter. As such, the piezoelectric component(s) are configured to enhance ultrasonic imaging of the catheter, e.g. when activated by a stimulator assembly.

  • Publication number: 20180177980
    Abstract: The present invention is directed to an echogenic member assembly for use with a catheter assembly. The echogenic member assembly includes at least one echogenic member having a cylindrical body extending between a first end and a second end. Thus, the body defines a longitudinal length between the first and second ends. Further, the cylindrical body has an exterior surface extending from the first end to the second end. The exterior surface includes a plurality of discontinuities arranged in a predetermined pattern so as to enhance ultrasonic imaging. In addition, the longitudinal length of the echogenic member is less than a total length of a catheter of the catheter assembly. As such, the echogenic member provides enhanced ultrasonic imaging to the catheter assembly without compromising the inherent flexibility of the catheter.

  • Patent number: 7697430
    Abstract: A packet scheduler includes a packet manager interface, a policer, a congestion manager, a scheduler, and a virtual output queue (VOQ) handler. The policer assigns a priority to each packet. Depending on congestion levels, the congestion manager determines whether to send a packet based on the packet's priority assigned by the policer. The scheduler schedules packets in accordance with configured rates for virtual connections and group shapers. A scheduled packet is queued at a virtual output queue (VOQ) by the VOQ handler. In one embodiment, the VOQ handler sends signals to a packet manager (through the packet manager interface) to instruct the packet manager to transmit packets in a scheduled order.
