An EUS access needle enters a target cavity or duct under endoscopic ultrasound (EUS) guidance and places a guidewire; in EUS-guided pseudocyst drainage it gives the puncture and the guidewire. SonoTip AccessPro is a single-use 19G EUS needle: blunt stainless steel cannula, cutting nitinol stylet, 0.035 inch guidewire lumen. It is used for access, guidewire placement, aspiration and injection.

An EUS-guided access needle system designed to support therapeutic EUS interventions and guidewire passage.
An EUS access needle (EUS-guided access needle) is used to enter a target cavity or duct under endoscopic ultrasound (EUS) guidance and to place a guidewire, while a sampling needle is made to bring back cells or a tissue core. SonoTip AccessPro (also written Access Pro) has a blunt stainless steel cannula and a cutting nitinol stylet with a trocar cut, so the cutting edge is on the stylet. Its lumen takes a guidewire of up to 0.035 inch, against 0.030 inch on our 19G sampling needles.
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.
The access needle gives the puncture and the guidewire for the drainage devices that follow. SonoTip AccessPro is 19G, takes a guidewire of up to 0.035 inch and has a 2.1 mm sheath. Once the guidewire is in the cavity, the tract is widened and kept open with stents. Our Cystogastrostomy Set is a separate product for drainage into the stomach or duodenum. It punctures with its own high frequency needle knife.
The ESGE 2022 therapeutic EUS guideline prefers EUS-guided biliary drainage over percutaneous drainage in malignant distal biliary obstruction after failed ERCP, where expertise is available (strong recommendation, moderate quality evidence). It makes no recommendation on needle size, and the choice follows the guidewire to be used. SonoTip AccessPro is 19G and takes a guidewire of up to 0.035 inch. The choice of needle is the physician's decision.
