  • Publication number: 20200197084
    Abstract: A cooling radiofrequency ablation probe for delivering electrical and thermal energy to tissue of a patient's body is provided. The probe comprises a handle having an upper portion, a lower portion, and a Luer connector. The probe further comprises an extended electrocap assembly interfacing with one end of the handle, and a cable-tubing assembly interfacing with another end of the handle. The cable-tubing assembly includes an electrical cable that terminates at an electrical connector and a dual-lumen fluid tubing that terminates at inlet and outlet fluid connectors. An active tip of the extended electrocap assembly is configured to deliver the electrical and thermal energy to the tissue of the patient's body.

  • Patent number: 10327997
    Abstract: A connector for coupling to a base of an indwelling device equipped with a circular hub having a radius, a top surface, a side surface, and a circumferential recess defined in the side surface. The connector has a resilient assembly including a plurality of release buttons extending from the resilient assembly and may include a conduit defining a fluid pathway through the connector. Each release button has a finger contact zone and a catch. The catch is configured to releasably engage the circumferential recess. The connector is coupled by positioning the connector on the circular hub and depressing the connector until the catches engage the circumferential recess such that the connector is configured to rotate completely about the circular hub. The connector is decoupled from the hub by pressing the release buttons to reversibly displace the respective catches radially to disengage from the circumferential recess.

  • Patent number: 10245401
    Abstract: A subglottic suctioning system with a tracheal tube having a ventilation lumen, a cuff inflation lumen, and a suction lumen are disclosed which may help reduce the incidence of ventilator associated (or acquired) pneumonia. The suction lumen communicates with the space in the trachea above the cuff where secretions accumulate. The suction lumen has a valve on the proximal end for connection to a source of vacuum. The valve is adapted to interrupt the supply of vacuum to the suction lumen to allow for the introduction of a rinsing fluid in its place and to automatically re-establish the connection to the source of vacuum upon completion of rinsing. The rinsing fluid aids in maintaining an open suction lumen and may include medicaments and mucolytic agents to enhance or promote healing or to alter the properties of the mucus to make removal easier. The user may easily and repeatedly alternate suction and rinsing fluid through the suction lumen, i.e.

  • Patent number: 9434977
    Abstract: There is provided a lateral flow assay that can provide an indication of Gram negative (GN) or Gram positive (GP) infection (or both) within 30 minutes, and desirably in less than 15 minutes. The immediate result would signal the presence of Gram negative bacteria, Gram positive bacteria, both Gram negative and Gram positive bacteria, or no bacteria detected. The detection level would be above a specific bacterial concentration threshold that is clinically significant infection source (e.g. 10^3 cfu/ml) versus the presence of a colonizing bacteria that is not a part of the active infection.

  • Patent number: 9381338
    Abstract: A connector for coupling to a base of medical device equipped with a circular hub having a circumferential recess. The connector includes a cap having a top surface, a bottom surface, a central region, and a circumferential region. The cap defines at least two slots extending from the circumferential region towards the central region, the slots defining the cap into at least one lobe. The at least one lobe has an outward projecting lift tab and an inward projecting catch. Positioning the connector on the circular hub and depressing the connector engage the catch with the circumferential recess of the circular hub so the connector can rotate completely about the circular hub. Lifting the one lift tab to reversibly displace the lobe and its respective catch radially to disengage from the circumferential recess decouples the connector.

  • Patent number: 9364652
    Abstract: A connector for coupling to a base of medical device equipped with a circular hub having a circumferential recess. The connector includes a cap having a top surface, a bottom surface, a central region, and a circumferential region. The cap defines at least two pairs of slots extending from the circumferential region towards the central region dividing the cap into at least two fixed lobes and at least two resilient lobes. Each resilient lobe has an outward projecting lift tab, an inward projecting catch, and at least a resilient region. Positioning the connector on the circular hub and pressing the connector engage the catches with the circumferential recess of the circular hub so the connector can rotate completely about the circular hub. Lifting at least one lift tab to reversibly displace the resilient lobe and its respective catch radially to disengage from the circumferential recess decouples the connector.

  • Patent number: 9155684
    Abstract: An inflatable retention system for an enteral feeding tube having a base deployed outside the human body and an indwelling retainer which is deployed within a lumen or cavity of the body by insertion through a stoma from outside the body. The retention system includes a tube having a proximal end, a distal end, an external tube diameter, and tube walls defining a feeding lumen and an inflation lumen. The retention system also includes an inflatable balloon located at a distal end of the tube in fluid communication with the inflation lumen, the balloon having thin, flexible walls, a predetermined spheroid shape, and a volume at which a fluid in the balloon is under no pressure such that upon inflation with a fluid to pressurize fluid in the balloon, the balloon assumes a stable spheroid shape and exhibits a substantially linear pressure versus volume curve.

  • Patent number: 8974399
    Abstract: There is provided a device for sampling bodily fluids. Some embodiments have a handle, a lumen, and a diverter valve. The distal end of the handle is adapted to connect with a sampling device and is in fluid communication with the lumen. There is a vacuum connection on the proximal end of the handle that is also in fluid communication with the lumen. A suction valve may desirably be located in the lumen to control the application of vacuum from the vacuum connection to the sampling device. The diverter valve directs the flow through the lumen such that a sample from the patient goes into a sputum trap when the trap is connected. The device may further have a saline port in fluid communication with the lumen, located distal to the suction valve, for rinsing the tube and diluting secretions.
