An EUS-guided access needle system designed to support therapeutic EUS interventions and guidewire passage.
Its purpose is taking a sample, gaining access and injecting during endoscopic procedures, and its indications are cytological examination, biliary obstruction that conventional ERCP cannot reach, and pseudocysts and cysts that may degenerate. Its lumen takes a guidewire up to 0.035 inch, so the access step connects to the ERCP accessories.
The sheath outer diameter is 2.1 mm, and the working channel has to be at least 0.2 mm larger than the outer diameter of the device.
