USER MANUAL
1. Introduction
Operating Principle
The Navigator 2.0 System detects presence of gamma rays, emitted from radioactive isotopes in
body organs or tissue. System use requires the Navigator 2.0 Control Unit, which allows the user to
adjust the system's settings and produces a variety of signal outputs. The control unit is powered by
battery. The system provides an increasing or decreasing sound and visual counts that vary as
level of gamma radiation increases or decreases.
The control unit works in conjunction with a hand-held probe that is connected to the control unit
either via a cable or wireless technology. Detecting gamma radiation with a hand-held probe is
based on nuclear physics laws which allow detection of radiation emitted from a small source.
Placing probe close to a radioactive site increases number of counts detection and localization
occurs. Excision of the region of interest is then performed using standard surgical technique. On
the other hand, as the distance between the probe and the radiation source is increased, the sound
signal and number of counts decrease.
The control unit is used with any of the following Navigator
™ hand-held probe models. The probes
differ primarily in their size, shape, detector technology and connection to the control unit.
·
14mm Wireless Pilot Probe
™ (angled tip)
·
14mm Standard Lymphatic Mapping Probes (angled tip & straight tip)
·
12 mm Lymphatic Mapping Probe (angled tip)
·
11mm Superficial Head & Neck Probe (straight tip)
·
10mm Daniel Lung Probe
™ (straight tip)
·
10mm Laparoscopic Probes (310mm & 190mm Lengths, straight tips)
The system is supplied non-sterile. This manual includes guidelines for the use of the probes and
accessories within the sterile field.
Intended Use
For the detection and quantification of gamma radiation from gamma-emitting isotopes in the body or
tissues. Use for non-imaging procedures to measure the amount of radionuclide absorbed by a
particular organ or body region.
Indications for Use
For the detection and quantification of gamma radiation from gamma-emitting isotopes in the body or
tissues. Use for non-imaging procedures to measure the amount of radionuclide absorbed by a
particular organ or body region in open-surgical, laparoscopic or thoracoscopic surgical procedures.
Manufacture and Distribution
The system is manufactured and distributed by Dilon Technologies of Newport News, VA. Please
direct all inquiries about the Navigator 2.0 to Dilon Technologies.
The year of manufacture on the control unit are indicated in the first four numbers of the serial
number. The year of manufacture on the probe are indicated in the last two numbers of the serial
numbers.
