  • Patent number: 10602960
    Abstract: A device and method are described for navigating and positioning a central venous catheter into the venous system using two different modes of location. For example, a peripherally inserted central catheter (“PICC”) may be navigated and positioned within the superior vena cava. A light emitting element is used in the first mode to navigate the PICC to the superior vena cava. To improve visibility during navigation, the light emitted from the light emitting element may include a narrow range of wavelengths that generally matches the wavelengths of light that are transmissable through a light absorbing material defining the wall of the catheter. A conductive medium is used in the second mode to monitor an ECG signal in order to position the PICC in the superior vena cava. One advantage of this procedure is that X-ray visualization can be eliminated to reduce the danger associated with X-rays.

  • Patent number: 9346181
    Abstract: A cutting tool is provided for cutting the end of a catheter to provide custom length catheters. The cutting tool has a cutting member that moves within the cutting passageway in the housing. The catheter is positioned within a catheter passageway in the housing. The cutting passageway transacts the catheter passageway so that a blade on the cutting member crosses the catheter passageway and cuts through the width of the catheter to form a cut end on the catheter.
