  • Patent number: 5911706
    Abstract: An implantable single or dual-lumen or more lumen device for repeated accessing vessels within a body. The device uses a resilient material to form a seal, and has a smooth streamlined flowpath with no flow discontinuity. The device is joined to a catheter, in most cases, such that fluids can be extracted from or injected into the vessel to be accessed. The device is designed for the high flowrates, on the order of 150 and greater milliliters per minute, associated with hemodialysis, plasmapheresis, and other fluid exchange therapies. In such applications smooth flow streaming is important to minimize damage to the blood. A corresponding straight-needle apparatus is designed to mate and lock with the access device, where alignment and open flowpath is ensured. A valve seal incorporates opposing very hard surfaced guide elements that are retained and in intimate contact with the seal itself.

  • Patent number: 5894011
    Abstract: A device for selectively controlling the direction of blood flow to and from the patient during hemodialysis comprises two interlocking disks that rotate in relation to each other without separating. The two disks have fluid fittings that allow the blood lines attached to the patient to connect to one of the disks and the blood inlet and outlet for the hemodialysis machine to connect to the other. The center of each fluid fitting is a channel that aligns to a corresponding channel in the other disk. The disks rotate between two fixed relative positions, referred to herein as preferred alignments. The preferred alignments are such that the line drawing blood from the patient in the first preferred alignment becomes the line returning blood to the patient in the second preferred alignment, and the line returning blood to the patient in the first preferred alignment becomes the line drawing blood from the patient in the second preferred alignment.

  • Patent number: 5346502
    Abstract: The ultrasonic instrument includes a shaft having an integral sheath of PTFE encompassing the shaft and attached solely to the shaft. At the proximal end of the shaft, wrench flats are exposed through openings in the sheath and grooves cooperate with complementary ribs on the sheath, to prevent relative longitudinal and rotational displacement of the sheath and shaft. The sheath is in contact with the shaft at the nodes along the shaft. The diameter of the sheath is about 5 mm whereby the instrument may be used with a 5 mm trocar port. To manufacture the instrument, the sheath is initially formed to a diameter equal to or less than the diameter of the shaft and then mechanically expanded. Subsequently, the sheath is heat-shrunk about the shaft and rolled continuously along the shaft, except at regions corresponding to the nodes along the shaft, to expand the sheath to a larger diameter to space the sheath from the shaft except at the nodes of the shaft.
