Unet™ Stone Basket (Three-wire)

● Secure three-wire capture design with super-elastic nitinol construction ensures uniform force distribution, stable stone grip, and reduced risk of stone displacement

● Excellent maneuverability and trackability through a stainless steel braid-reinforced shaft with hydrophilic coating, providing kink resistance and precise 1:1 torque control

● Enhanced visibility and safety with radiopaque markers for clear fluoroscopic visualization and an atraumatic tip to minimize mucosal injury

● Ergonomic one-handed operation integrates basket opening, closing, and rotation functions for streamlined stone capture and improved procedural efficiency


Intended Use

Unet™ Stone Basket (Three-wire) is designed for capturing, securing, and removing urinary tract stones and stone fragments during endoscopic urological procedures. It supports effective stone retrieval, stone clearance, and maintenance of urinary tract patency.

Technical Features

● Three-wire nitinol basket architecture provides symmetrical expansion and balanced circumferential force for stable stone capture while minimizing mucosal trauma

● Optimized stone retention design enhances engagement stability and reduces the risk of fragment displacement during withdrawal

● 1:1 torque-controlled rotational mechanism enables precise 360° steering for accurate alignment within tortuous ureteral segments and lower pole calyces

● Low-profile hydrophilic-coated sheath (4.5 Fr) supports smooth passage through flexible and rigid ureteroscopes while maintaining irrigation flow and scope deflection control

● Radiopaque proximal and distal markers ensure clear fluoroscopic visualization of deployment, positioning, and stone capture

● Available in reusable (autoclavable) and sterile single-use configurations to accommodate different clinical and institutional requirements


Clinical Applications

● Ureteroscopic Stone Extraction (URS): Primary retrieval device for ureteral and renal stones during semi-rigid and flexible ureteroscopy, particularly effective for stones 5–15 mm in diameter.

● Basket-Assisted Lithotripsy: Stabilizes stones during laser lithotripsy, preventing fragment migration and enabling controlled, piece-by-piece extraction.

● Lower Pole Stone Retrieval: Enhanced deflectability and rotational control facilitate access to challenging lower pole calyces.

● Stone Relocation Procedures: Enables controlled proximal migration of distal ureteral stones to the renal pelvis for optimized lithotripsy.

● Pediatric Ureteroscopy: Low-profile design and atraumatic nitinol wires support safe and precise stone retrieval in pediatric patients.

● Residual Fragment Clearance: Effective for removing small residual fragments following lithotripsy to achieve stone-free outcomes.


Structure Composition

● Basket Head: Tipless design constructed from braided nitinol wire, providing high flexibility and shape retention during repeated stone retrieval

● Composite Braided Outer Sheath: Reinforced sheath design enables smooth advancement, retraction, and synchronous rotation of the basket, even under extreme scope angulation

● Tight-Closure Mechanism: Ensures secure basket closure and smooth reintroduction through the working channel

● Available Sizes: Sheath outer diameter options include 1.7 Fr, 1.9 Fr, and 2.2 Fr
