  • TUBING ASSEMBLY AND SIGNAL GENERATOR PLACEMENT CONTROL DEVICE AND METHOD FOR USE WITH CATHETER GUIDANCE SYSTEMS
    Publication number: 20110230828
    Abstract: A tubing assembly having a signal generator placement control device for use in conjunction with electronic catheter guidance systems. The control device facilitates control of the position the guidance systems' signal generator relative to the end of the tubing assembly. The tubing assembly includes a tubular insulator coupled to one end of the control device, and the tubing assembly includes a tubular connector attached to the other end of control device. Also, the tubing assembly includes a catheter attached to the tubular connector and an end member attached to the catheter.

  • MEDICAL DEVICE POSITION GUIDANCE SYSTEM WITH WIRELESS CONNECTIVITY BETWEEN A NONINVASIVE DEVICE AND AN INVASIVE DEVICE
    Publication number: 20080097475
    Abstract: A medical device position guidance system having a noninvasive medical device communicable with an invasive medical device. The system provides outputs useful to assess the position of an invasive medical device in an animal, such as a human. A magnetic field is used to gather information about the position of the invasive device. Radio waves are used to communicate this information between the noninvasive device and the invasive device.
