  • Patent number: 11937886
    Abstract: Disclosed biopsy markers are adapted to serve as localization markers during a surgical procedure. Adaptation includes incorporation of materials detectable under ultrasound during surgery, as well as features for co-registration with image guidance or other real-time imaging technologies during surgery. Such biopsy markers, when used as localization markers, improve patient comfort and reduce challenges in surgical coordination and surgery time. Additional disclosed biopsy markers are adapted to serve as monitoring and/or detection apparatuses, Localization of an implanted marker may be done with ultrasound technology. Ultrasound image data is analyzed to identify the implanted marker. A distance to the marker or a lesion may be determined and displayed. The determined distance may be a distance between the ultrasound probe and the marker or lesion, a distance between the marker or lesion and an incision instrument, and/or a distance between the ultrasound probe and the incision instrument.

  • Publication number: 20240085033
    Abstract: A direct outdoor air system may include an enclosure having an air inlet to direct environmental air into the enclosure, a heat exchanger section to receive the environmental air and direct conditioned air to an air outlet of the enclosure, and a blower section to receive the environmental air from the air inlet and direct the environmental air to the heat exchanger section via an air flow path between the blower section and the heat exchanger section. The air outlet may direct the conditioned air to a conditioned space. The direct outdoor air system may also include a heat exchanger disposed in the heat exchanger section to condition the environmental air, generating the conditioned air, and a blower disposed in the blower section to motivate the environmental air through the air flow path. Additionally, a heat exchange area of the heat exchanger may be oriented vertically relative to gravity.

  • Patent number: 11913305
    Abstract: A seal arrangement includes a body having a face seal, and a flexible arm extending from the body. The arm includes a contact seal. A flapper valve, includes a housing, a flapper and a flapper seat. The flapper seat includes a body having a face seal positioned to make sealing contact with the flapper in selected flapper positions A method for sealing a flapper valve includes closing a flapper toward a seat and making a seal, by deflecting a flexible arm of the flapper seat that supports a contact seal. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a seal arrangement disposed within or as a part of the string.

  • Patent number: 8858584
    Abstract: An emergency transection intervention device has an elongated catheter (4) with a movable nose cone dilator (8) temporarily closing off the first end of the elongate catheter, a haemostatic seal (6) on a second end of the catheter and closing off the second end of the elongate catheter. First and second inflatable balloons (12, 14) are spaced apart on the elongate catheter, and there is an aperture (16) in the elongate catheter between the balloons and the haemostatic seal. The emergency transection intervention device can be deployed into a blood vessel of the human or animal body, during an emergency procedure for instance, with the balloons positioned either side of a damaged portion of the vessel and the balloons inflated such that a region of the vessel between the balloons is isolated. The nose cone dilator can then be advanced to allow blood flow through the elongate catheter and exit through the aperture in the elongate catheter to bypass the damaged portion of the vessel during repair.

  • Publication number: 20060185222
    Abstract: A fish line guide device formed by a plurality of removably engageable guide members forming a serpentine fish line path. The guide members can be engaged to a surface of a basket worn by an angler or to the surface on which the angler is standing such as a boat deck. Engagement is accomplished by base mounts which engage with the base end of the guide members and hold the guide member substantially perpendicular from the surface. A sandwiched engagement of the guide member and base mount or a suctional engagement of the base mount to a surface, or a tongue and groove style engagement provides the projecting mount of the guide members to the surface. The guide members may also be engaged to a flexible surface layer which is then supported upon a support surface adjacent to an angler.
