Radial EBUS Probes

Endobronchial Ultrasound

Radial EBUS Probes

Compatible with a channel diameter of 1.7 mm or more, depending on the model chosen. (See available models below) Radial EBUS probes can be inserted directly through the bronchoscope or used with the Olympus Guide Sheath Kit for an effective solution that can aid in accessing and sampling peripheral pulmonary lesions.

Key Benefits

  • Precise, real time confirmation: Olympus radial EBUS probes provide real-time confirmation of lesion location.1
  • 360-degree, real time visualization:  Radial EBUS provides a 360-degree image of the airway wall and surrounding structures external to the airway. The mechanical scanning technique produces a real-time ultrasound image enabling direct visualization of the lesion location for sampling.1
  • Proven technology: Clinical data demonstrates that radial EBUS provides an adequate alternative to conventional transbronchial bronchoscopy, without the increased risk of clinical complications associated with transthoracic needle aspiration (TTNA).2

Complications from bronchoscopy are rare and most often minor, but if they occur, may include breathing difficulty, vocal cord spasm, hoarseness, slight fever, vomiting, dizziness, bronchial spasm, infection, low blood oxygen, bleeding from the biopsied site, or an allergic reaction to medications. Only rarely do patients experience other more serious complications (for example, collapsed lung, respiratory failure, heart attack and/or cardiac arrhythmia).
