Product Details
The Expect Slimline (SL) Needle is an EUS-FNA needle that is indicated for four diagnostic and therapeutic indications, providing physicians with clinical options to manage their patients.
The Expect Slimline (SL) Needle is designed to sample targeted submucosal and extramural gastrointestinal lesions through the accessory channel of a curvilinear echoendoscope. It can also be used for the delivery of injectable materials (fluids) or fiducials into tissue or for passage of accessory devices.
Compatible with New Fiducial Markers: The Expect Slimline (SL) 22ga EUS Needle is compatible with the new LumiCoilTM Platinum Fiducial Markers, which feature platinum construction designed for clear visibility in CT, X-Ray, EUS, CBCT, and MRI procedures.* Two loading options are available for the straight marker configuration based on preference; through the needle tip or through the needle’s luer**.
Sharp needle grind: For precise targeting and sampling
Cobalt-Chromium construction***: Provides benefits over some stainless steel alloys including greater needle hardness and excellent tensile properties to deliver:1****
- Superior needle penetration1
- Improved pushability and kink resistance1
- Increased resistance to needle damage or deformation after multiple passes1
Echogenic pattern extends onto needle tip:
- Provides precise guidance within the target site
- Helps maintain tip visibility at all times
Stylet cap with integrated clip
- Keeps stylet safely contained
Custom sheath sizes
- Designed to improve passability
Control ZONE™ and Lubricomp Polymer
- Two ergonomically defined areas designed to optimize control during actuation
The Expect Slimline (SL) 19ga Flexible EUS-FNA Needle is compatible with the Mauna Kea Technologies Cellvizio AQ-Flex™ 19 Confocal Miniprobes™ accessory device to perform optical biopsy procedures. Learn more about Cellvizio.
