  • Patent number: 10426514
    Abstract: A self-dilating cannula for introduction into a patient's vasculature includes an elongate body and an atraumatic tip. The elongate body has a proximal end, a distal end, and a fluid-flow lumen extending therebetween. The atraumatic tip is positioned at the elongate body's distal end and has a blunted end and a conical shape. The atraumatic tip includes a plurality of fluid-flow openings proximal to the blunted nose that are configured to disperse fluid from the fluid-flow lumen in a plurality of directions with respect to the atraumatic tip. The atraumatic tip also includes an opening in the blunted nose that is sized to a guidewire.

  • Patent number: 6413233
    Abstract: Method and apparatus to automatically monitor and control a perfusion hyperthermia treatment using a system including one or more programmed computers, and mechanical and sensor subsystems. The system includes a fluid path between a patient and an external fluid-treatment subsystem, wherein control of the external fluid-treatment subsystem includes feedback from sensors coupled to the patient. The resulting integrated system provides automated monitoring and control of the patient, the external fluid-treatment subsystem, and the treatment. In one embodiment, the fluid passing between the patient and the external fluid-treatment subsystem is blood. In one embodiment, an apparatus and method are provided for using a computerized system for a perfusion hyper/hypothermia treatment of a patient which obtains a body fluid having a temperature. A plurality of temperature signals representative of temperatures at each of a plurality of patient locations on or within the patient are coupled to the computer system.

  • Patent number: 5391142
    Abstract: Apparatus and a method for performing extracorporeal treatment of a patient's blood for various conditions. The apparatus includes means by which an extracorporeal blood circuit is defined. Such a blood flow circuit includes first means for cannulating a vein of a patient to define a blood egress point and second means for cannulating an artery of the patient to define a blood ingress point. A discontinuous conduit is provided to interconnect, in part, the first and second cannulating means. The apparatus also includes a module which includes a conduit portion. The module integrates a number of components into a single unit, and the conduit portion thereof is able to be interposed in the discontinuity in the discontinuous conduit to complete the blood flow circuit.
