Olympus Introduces Forward-Viewing Curvilinear Ultrasound Gastrovideoscope

Olympus has launched its 510(k)-cleared forward-viewing curvilinear ultrasound gastrovideoscope.

The design of Olympus’ new EUS scope with forward-viewing optics makes it an ideal interventional tool, the company claims. The design of the scope is significant because it provides a reduced distal tip length compared to its oblique-viewing counterparts. The combination of a shorter tip with wider angulation capabilities (180 degrees up) delivers enhanced maneuverability and handling, according to executives. In addition, the scope’s straight channel enables therapeutic devices to be delivered directly (or head on) to the target site, potentially providing easier access to regions of interest.

The scope’s enhanced maneuverability and handling potentially can improve visualization of fundus diseases, which can be challenging to see and diagnose. In addition, an auxiliary water jet potentially provides better acoustic coupling and saves money by eliminating the need for a balloon.

“The forward-viewing therapeutic echoendoscope is a major advance for interventional endoscopy,” said Kenneth Binmoeller, M.D., medical director of the Interventional Endoscopy Service at California Pacific Medical Center. “It is the first true ‘hybrid’ ultrasound endoscope, enabling both ultrasound and endoscopy-guided interventions with the same instrument. This will facilitate existing EUS-guided therapies, such as pseudocyst drainage, as well as enable new EUS-guided treatments.”

The TGF-UC180J is powered by a next-generation ProSound F75 Ultrasound Imaging Platform the company developed in partnership by Hitachi Aloka Medical Ltd. The platform helps doctors more accurately diagnosis diseases and cancers of the GI track and surrounding organs. The scope also is backward compatible with prior generation processors, including the Olympus EU-ME1 and Hitachi Aloka SSD-α10.

“We are pleased to introduce this newest advance in EUS technology,” said Luke Calcraft, president of the Medical Systems Group at Olympus Corporation of the Americas. “The TGF-UC180J has the potential to pave the way for new EUS-guided treatments and assist healthcare facilities in their efforts to meet the triple aim of Affordable Care through advanced diagnostic and therapeutic capabilities, clinical and cost efficiencies, and less invasive interventions for treatment of diseases and cancers in the GI tract.”

Olympus pioneered endoscopic ultrasound (EUS), which combines ultrasound technology with endoscopy to better visualize the tissues of the digestive tract and adjacent anatomical structures inside the human body. Conventional ultrasound is performed by placing a transducer against the skin to produce images of internal organs. With EUS, the transducer is endoscopically inserted into the body through the digestive tract, putting it closer to the region of interest to obtain higher resolution images.  

The demand for minimally invasive procedures continues to grow with the introduction of more advanced technologies. More than 250,000 EUS outpatient procedures were performed in the United States in 2011 and that number is expected to grow at a 6 percent compound annual growth rate for the next five years, according to estimates.

The advanced design of the TGF-UC180J scope can help healthcare providers address the key requirements of healthcare reform, including:

— Increased quality of care – EUS drives optimal patient outcomes through easy identification and more accurate staging of diseases and cancers in the GI tract.
— Decreased costs – Interventional procedures can be performed in the GI suite which saves operating room time. In addition, the forward-viewing scope does not require a balloon, reducing accessory expenditures.
— Enhanced Patient Satisfaction – EUS offers patients a less invasive treatment compared to surgical interventions, and procedure times may be shorter.

Olympus Medical Systems Group, a division of global technology leader Olympus, develops solutions for healthcare professionals that help improve clinical outcomes, reduce overall costs and enhance quality of life for their patients.
