The Web II Memory Extraction Basket is a biliary and pancreatic duct dislodger, designed for endoscopic retrieval of biliary stones and foreign bodies. Its variants include double lumen, soft wire, helical, and hard wire configurations, each tailored for specific extraction challenges during endoscopic retrograde cholangiopancreatography (ERCP). The device employs memory wire technology to maintain shape and facilitate precise navigation within the biliary tree, while the fusion wire guided basket ensures controlled retrieval of calcified or fragmented stones.
Supplied sterile and intended for single-use, these baskets are categorized under FDA 510(k) clearance (K171969) and comply with the Medical Device Directive (MDD). They are non-magnetic and intended for use in non-lithotripsy applications, requiring compatibility with standard endoscopic equipment. Storage instructions specify maintenance of sterility until first use, with sizes and lumen configurations detailed in the specifications. Authorized for use in gastroenterology and urology, these devices are classified under product code LQR (Device Class II)

Frequently asked questions
What types of stones or foreign bodies is this basket designed to retrieve during ERCP procedures?
The Web II Memory Extraction Basket and its variants are specifically designed for endoscopic retrieval of biliary stones and foreign bodies during ERCP. The different configurations—such as double lumen, soft wire, helical, and hard wire—are tailored to handle various extraction challenges, including calcified or fragmented stones, ensuring precise navigation and controlled retrieval within the biliary tree.
Are these baskets reusable, or are they intended for single-use only?
These baskets are supplied sterile and explicitly intended for single-use only. The packaging maintains sterility until the first use, so reuse is not recommended or supported by the manufacturer.
What wire technologies are included in these baskets, and how do they differ?
The baskets feature memory wire technology to maintain shape during navigation, along with specialized variants like fusion wire-guided baskets (for controlled retrieval of calcified stones) and configurations such as soft wire, helical, and hard wire. These variations address different extraction challenges, such as flexibility for delicate tissues or rigidity for dense stone fragments.
Can these baskets be used with standard endoscopic equipment, and are they compatible with lithotripsy?
Yes, these baskets are designed to be compatible with standard endoscopic equipment. However, they are not intended for lithotripsy applications—they are labeled as non-lithotripsy extraction baskets, meaning they should not be used in conjunction with devices that fragment stones mechanically.
How should these baskets be stored to preserve sterility before use?
The baskets must be stored in their original packaging until the time of first use to ensure sterility is maintained. The manufacturer’s instructions specify that the sterile barrier should remain intact until deployment during the procedure.
