  • 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.
