  • Publication number: 20230302267
    Abstract: The disclosure relates to a subcutaneously implanted port device for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein may reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a tapered seat for receiving an access tube, the first tapered seat having a proximal portion, a distal portion, and a conical section extending between the proximal portion and the distal portion; and an interface surface configured to engage a blood vessel or a vascular access catheter. The proximal portion of the tapered seat is configured to receive the access tube therethrough, and the tapered seat creates a mismatch fit with a diameter of the access tube when in use for an increase in flow during treatment.

    Abstract: A method of manufacturing an armour layer of a flexible pipe for transporting fluid from a subsea location and apparatus are provided. The method comprises winding a first length of composite tape to form a first section of the armour layer and positioning an end region of the first length of composite tape over an end region of a second length of composite tape to form an overlapping tape section. Heat and pressure is applied to the overlapping tape section to form a joined overlapping tape section in which the first length of tape is joined to the second length of tape such that the joined overlapping tape section has a lap shear strength of at least 11 MPa. The joined overlapping tape section and the second length of composite tape are wound to form a second section of the armour layer.
