  • Publication number: 20240058166
    Abstract: A process and related assemblies for delivering slush through a tube towards a patient. Obtaining an elongated container partially filled with slush with a port end that has a first port and a second port. Placing the first port in fluid communication with tubing for delivery of slush towards the patient. Placing the second port in fluid communication with a source of gas which may be air. Subjecting the elongated container to automated repetitive movements so that the slush in the partially filled elongated container moves against interior surfaces within the elongated container. Ideally, two different forms of repetitive motion are used to impose complex movement upon the slush within the elongated container. Applying a pressure gradient to cause slush to flow out of the first port towards the patient. The elongated container may be made from a slush bottle with a reversibly engaged cap with the two ports.

  • Publication number: 20210236223
    Abstract: A heating system for providing heat to a draped basin containing liquid above the drape. In addition to having at least one temperature sensor that controls a flow of electricity to the heating element, the system has at least one air gap detector in thermal contact with the heating element. Each air gap detector responding to a temperature above a high setpoint temperature for that air gap detector by interrupting the flow of electricity until detecting that the temperature has fallen below a reset setpoint temperature for that air gap detector so that an air gap in proximity to the one of the air gap detectors is prevented from causing a severe temperature excursion in a portion of the draped basin. Thus, the drape is protected from a local temperature excursion.

  • Patent number: 10973601
    Abstract: Drapes for covering fluid heating devices having basins. Some drapes have a set of at least one positioning component trapped between the drape basin layer and the drape device layer by a set of bonds. The positioning component aligns the drape with the basin bottom. Optionally, the drape may have a low-slip film for basin contact and a non-slip film for at least a portion of the drape beyond the basin. Alternatively, a single layer drape may have a set of at least one positioning component bonded to the drape. Some drapes have basin-shaped sterile vented barrier with vents to allow the sterile vented barrier to be inserted into the basin and to vent air out of the basin. The heating system for the fluid heating device may interrupt electricity provided to a heating element when a temperature sensed at an air gap detector exceeds a high temperature setpoint.

  • Publication number: 20210085298
    Abstract: A core biopsy instrument for taking samples of tissue such as prostate tissue comprises a handle configured to releasably receive a cartridge that holds a core collector. In use, after loading a cartridge in the handle, a spring drives the core collector into target tissue and shortly thereafter, in less than a second, a spring drives a cannula over the core collector to cut tissue in a trough thereof from surrounding tissue. The core collector is withdrawn proximally to its initial position in the cartridge and the cartridge is removed from the handle. The cartridge, with the core collector and the tissue sample therein is treated as needed for sending as a unit to a laboratory, thus preserving the orientation and completeness of the tissue sample therein.

  • Patent number: 10575984
    Abstract: A sleeve kit comprising a container sleeve and a sleeve cap which may be engaged with the container sleeve to form a sleeve assembly that envelopes a slush container, the sleeve kit including an attachment system to allow the sleeve cap to be engaged with the container sleeve to form the sleeve assembly and then become disengaged so that the slush container may be removed from the container sleeve. The attachment system may be a single-use attachment system to allow the sleeve cap to be engaged with the container sleeve to form the sleeve assembly. The container sleeve may have a set of at least one vent which allows air to move from an open top end of the container sleeve to a space between a bottom of an inserted slush container and a bottom of the container sleeve to facilitate removal of the slush container from the container sleeve.

  • Patent number: 9693892
    Abstract: Methods and apparatus for producing saline slush for surgical applications. Producing surgical saline slush in a slush bottle that is a rigid or semi-rigid, high integrity, sturdy container that resists punctures and leaks to better maintain a sterile barrier and does not rely on having an external object placed in the fluid to mix the slush. Slush is agitated within the slush bottle. Slush bottle features are discussed which agitate and condition slush for use in medical procedures. The slush bottle may be rotated using a pair of rollers. A slush station may have one or more compartments for the production of slush and a basin shell for maintaining slush as slush in a basin. Specialized techniques for a vertical slush bottle are discussed.

  • Patent number: 9549843
    Abstract: Creation of surgical slush having desirable mechanical properties by chilling a closed slush container with liquid saline and an air gap. The closed slush container having interior surfaces that are smooth and hydrophobic to resist adherence of ice crystals. Moving the closed slush container so the contents move in a complex set of motions rather than constant rotation around a longitudinal centerline of the slush container as the liquid saline is converted into surgical slush with a mixture of liquid saline and ice crystals. Interior surfaces of the closed slush container move into and out of an air gap to help shed any ice crystals forming on the interior surfaces. In some instances, as the orientation of the closed slush container relative to gravity changes over time, different interior surfaces shed the ice crystals. An optional method for delivering surgical slush to the sterile field is included. The full range of the disclosure exceeds the scope of this brief abstract.

  • Patent number: 9114218
    Abstract: A series of implementations of open access sleeves for holding one or more closed containers of sterile fluid for use in medical procedures are disclosed. The open access sleeves may be adapted to provide heat to maintain the containers of sterile fluid above the ambient air temperature of the room. The provision of heat may be controlled by a control system. The control system may use a temperature measurement device to obtain a temperature representative of the container of sterile fluid and of the sterile fluid in the container. The access sleeve may be included in a device for maintaining an open volume of sterile fluid within a range of a target temperature to maintain the closed containers of sterile fluid at a temperature near target temperature for open volume of sterile fluid.

  • Patent number: 8309891
    Abstract: A liquid warming device for heating sterile fluids in a removable container is described with emphasis on the properties of the container interaction with the liquid warming device and with a drape that works with the container to maintain a sterile field above the drape and the top of the container. The interactions between a temperature sensor and a temperature well integrated in the removable container are disclosed. Also disclosed are various desirable aspects for a control system for a liquid warming device are provided. The liquid warming device can selectively employ a adapter in order to receive a container limited to a smaller diameter than the largest container diameter that can be accommodated by the liquid warming device. The small diameter container may receive a volume of sterile fluid so that the liquid warming device can maintain the sterile fluid in the small diameter container within a prescribed range of temperatures above ambient air temperature.
