  • Publication number: 20100036284
    Abstract: A guiding insert assembly is disclosed that has electromagnetic-radiation-elements at each of its ends. A guiding insert having these elements is suitable for use in conjunction with known equipment in the process of locating the distal end of the guiding insert being placed into a patient. The proximally located element of the guiding insert can be used instead of a connector for contact-less coupling of the guiding insert and the location determining equipment, using an inductive coupler, so as to couple signal to and from the guiding insert during the location process. The coupling device preferably includes an insert retention arrangement, a guiding insert identification means and an end of travel detector. The placement of a catheter over the guiding insert either after placement or at the time of placement is possible.

  • Patent number: 5099845
    Abstract: An instrument location determining device which has a radiating element forming part of the instrument to be inserted into an object. The element radiates a signal and the signal is detected by at least one receiving element. A signal energy level measurement device is coupled to the receiving element and it produces an energy level value for each one of the receiving elements. The distance of the radiating elements from the receiving element is calculated from the measured energy level values received by each of the receiving elements. The measured distance is then indicated to an operator of the instrument so that he can locate the instrument within the object.
