4A Stone Retrieval Basket (Nitinol)

SKU: 4A-UR-0048

The Nitinol Stone Retrieval Basket is an advanced endourological tool constructed from superelastic Nickel-Titanium (Nitinol) alloy shape-memory wire. Engineered for flexible ureteroscopy (RIRS), it maintains its pre-formed shape even under extreme scope deflection, allowing tipless capture of mucosal-adjacent renal calyx stones without tissue trauma.

Key Benefits

  • Superelastic Shape Memory: Nitinol wires bend without taking a permanent kink, returning to shape after extreme flexible scope deflection.
  • Atraumatic Tipless Geometry: Eliminates the distal wire tip, allowing the basket to lay flat against the calyceal wall to sweep flush stones safely.
  • Kink-Resistant Performance: Resists deformation during repeated stone captures, maintaining full expansion capabilities throughout long procedures.
  • Micro-Size Sheath Profiles: Available in sub-2 Fr diameters to maximize scope deflection and irrigation flow rates during laser lithotripsy.
  • True 1:1 Torque Transmission: Rotates smoothly with handle movement for precise orientation around target stones.

4A Screw Dilator

The Screw Dilator (Threaded Ureteral Dilator) is a unique endourological device featuring a continuous helical thread along its distal working end. By converting rotational torque into controlled forward axial motion, it allows urologists to advance through tough, fibrous urethral or ureteral strictures that resist direct axial pushing.

4A Path Finder (Track Finder / Guide Wire Finder)

The Path Finder (Track Finder) is a specialized endourological access instrument designed to facilitate precise guide wire placement and anatomical navigation through complex, strictured, or tortuous urinary tracts. Engineered for use during advanced endoscopic procedures such as ureteroscopy and percutaneous nephrolithotomy (PCNL), it acts as an auxiliary directional catheter to negotiate difficult pathology. Its atraumatic tip and flexible shaft enable urologists to bypass impacted calculi and severe strictures while establishing safe, continuous upper tract access.
