An EUS-FNA needle (EUS-guided fine needle aspiration needle) takes cells for cytology from pancreatic, submucosal and extramural lesions and from lymph nodes under endoscopic ultrasound (EUS) guidance. SonoTip ProControl is a single-use EUS aspiration needle on a stainless steel shaft, with a Twist-Lock handle and a VacLok™ syringe, in 19G, 22G and 25G.

The 19G model is the one that pairs with a 0.030 inch cyst guidewire.
An EUS fine needle aspiration (FNA) system with Twist-Lock technology for single-handed needle and tube length adjustment.
EUS-FNA (EUS-guided fine needle aspiration) is a sample taken with an aspiration needle passed through the working channel of the echoendoscope under endoscopic ultrasound (EUS) guidance. It brings back cells and cell clusters; the diagnosis is mostly cytological, and a cell block can also be prepared. The EUS-FNA needle is single use. EUS-FNA needles are also made by manufacturers such as Boston Scientific and Olympus; SonoTip ProControl from Medi-Globe is a stainless steel needle of the same product class, in 19G, 22G and 25G. The list is not complete and implies no ranking or superiority.
The FNA needle brings back cells; the FNB needle aims for a tissue core, and the FNB needle of this range is on the TopGain page. The ESGE 2025 guideline recommends on-site cytology (ROSE) when FNA is performed (strong recommendation, moderate quality evidence) and, without ROSE, at least 4 passes with an FNA needle against 2 with an end-cutting FNB needle. For solid pancreatic masses it prefers end-cutting FNB over FNA (strong recommendation, high quality evidence), and where ROSE is available FNA keeps a role. With ROSE, a network meta-analysis found no needle significantly superior to the others (Gkolfakis 2022). The choice of needle is the physician's decision.
They are three ways of applying suction. The suction method is the physician's choice: dry suction with a syringe, slow pull of the stylet, or wet suction, where the needle is filled with saline. Suction is closed before the needle leaves the mass. The pack holds a VacLok aspiration syringe with a 20 ml fill volume.
The models table pairs them: the 19G needle is 1.1 mm on a 2.1 mm sheath, and the 22G and the 25G needle are 0.7 and 0.5 mm on a 1.8 mm sheath. The sheath diameter is the one that has to pass the working channel of the echoendoscope.
The maximum guidewire diameter changes from model to model: up to 0.018 inch on the 22G needle and up to 0.030 inch on the 19G needle, where the recommended wire is a 400 cm nitinol cyst guidewire. The 25G model carries no guidewire figure.
The price depends on the model (19G, 22G or 25G) and the quantity. We do not publish a list price on this page. Use the quote button on this page for a fast quote. We quote for hospitals in Türkiye and answer international enquiries.
EUS needles fall into three groups by job. FNA needles bring back cells for cytology: SonoTip ProControl (stainless steel, 19G, 22G, 25G) and ProFlex (nitinol, 22G, coming soon). FNB needles aim for a tissue core for histology: SonoTip TopGain (19G, 22G, 25G) and TopGain Flex (nitinol, 22G, coming soon). Access needles enter a cavity or duct and place a guidewire: SonoTip AccessPro (19G, 0.035 inch guidewire). The Cystogastrostomy Set is a separate set for drainage. The guidelines name needle types, not products, and the choice of needle is the physician's decision.
