Endoscopic Ultrasound (EUS)

Committed to

Endoscopic Ultrasound

Diagnose and treat with confidence.

Endoscopic ultrasound (EUS) combines ultrasound and conventional endoscopy technologies to see beyond the walls of the gastrointestinal tract. EUS allows endoscopists to visualize all five layers of the GI tract, as well as surrounding tissue and organs.

Olympus offers a full product portfolio of EUS processors, echoendoscopes, miniature probes and needles to meet physician needs and preferences. These products can support diagnostic, therapeutic and interventional applications such as EUS-guided tissue acquisition, cyst drainage and biopsies of lesions/lymph nodes.


The Olympus portfolio offers a variety of echoendoscopes and miniature probes, creating a total endosonography solution for a full range of minimally invasive applications.

The diagnostic radial array echoendoscope provides a 360°, cross-sectional view of the GI tract and is primarily used for screening. The curvilinear echoendoscopes are useful for therapeutic applications such as tissue sample collection, cyst drainage, biopsies of lesions/lymph nodes and injection for pain management.

In addition, the endoscopic ultrasound miniature probes generate 360° images in the near field for excellent visualization of submucosal areas.


Visualization is key to accurately identifying tumors and tissue properties and boundaries. New and enhanced features available on Olympus ultrasound processors improve visualization and assist in diagnostic, therapeutic, and interventional procedures, leading to improved quality of patient care.

Olympus offers a full line-up of ultrasound processors designed to meet and exceed the needs of gastroenterologists performing a wide range of EUS procedures.

Therapeutic EUS

Olympus offers a line-up of single-use FNB and FNA needles to help achieve procedural goals for endoscopic ultrasound in a variety of clinical settings.

The EZ Shot 3 Plus FNB needle offers unparalleled access, enhanced puncturability, predictable trajectory and enhanced echogenicity in 19 G, 22 G, and 25 G configurations.

The EZ Shot 3 FNA needle features the same ergonomic handle as the EZ Shot 3 Plus and is designed for precision sampling of lesions, available in 19 G, 22 G and 25 G configurations to suit clinical preferences.


At Olympus, we are committed to innovation. We deliver today’s most comprehensive EUS solution, with a robust portfolio of EUS processors, echoendoscopes and devices.

Endoscopic Ultrasound is the difference between maybe and definitely.
