Description
The Minerva Nitinol Basket is a 4‑wire with Tip stone retrieval device designed to capture, reposition, and remove stones of varying sizes in the urinary tract. The Grasper–Basket configuration and atraumatic tipped distal end support controlled access in challenging anatomy while maintaining excellent kink resistance and shape memory.
Key Features
- Hybrid grasper–basket design to both grasp and encircle stones, including small fragments, in a single device.
- Four‑wire nitinol basket for superior flexibility, kink resistance, and reliable shape recovery after repeated cycles.
- Atraumatic distal tip to facilitate guided access into calyces and along tortuous ureteral segments while helping minimize mucosal trauma.
- Low‑friction, torque‑responsive shaft designed for smooth passage through the working channel and precise rotation under endoscopic visualization.
- Ergonomic handle for intuitive opening, closing, and rotation to support single‑handed operation and procedural efficiency.
- Single‑use sterile device to reduce cross‑contamination risk and eliminate reprocessing time.
Clinical Applications
- Endoscopic manipulation and retrieval of urinary stones in the ureter and renal collecting system during ureteroscopy and related minimally invasive procedures.
- Particularly suited when a guided, tipped basket is preferred to navigate tortuous anatomy or reach stones in difficult‑to‑access calyces.
- Can be used following intracorporeal lithotripsy to retrieve residual fragments and support stone‑free outcomes.
Technical Specifications
- Device: Single‑use nitinol Basket for stone retrieval.
- Basket configuration: 4‑wire nitinol basket with distal tip.
- Material: Nitinol basket wires; polymer/flexible sheath; metal/plastic handle.
- Intended anatomy: Kidney and ureter during flexible or semi‑rigid ureteroscopy.
- Compatibility: For use through the working channel of flexible and rigid ureteroscopes
- Use: Sterile, single‑use device; supplied ready to use in procedure pack.
Clinical benefits
- Atraumatic navigation and retrieval: Nitinol construction and a low‑profile tipped design support flexible navigation through curved ureters with less mucosal trauma than more rigid baskets, helping reduce post‑procedure pain and complications.
- Secure capture of variable stone sizes: The hybrid grasper–basket geometry combines end‑engaging grasping with circumferential capture, improving control when retrieving both small fragments and larger stones compared with conventional baskets alone.
- Support for higher stone‑free rates: Active basketing of fragments after lithotripsy is associated with improved stone‑free rates and fewer stone‑related emergency visits than leaving small fragments to pass spontaneously.
- Improved safety in complex anatomy: End‑engaging hybrid designs allow controlled capture and repositioning of stones in difficult lower‑pole or stenotic segments, potentially lowering the force needed for extraction and reducing risk of ureteral injury.
Workflow & efficiency benefits
- Single device for grasping and basketing: Basket functionality allows stone capture, repositioning, and extraction with one device, decreasing the need for multiple instruments and exchanges during ureteroscopy.
- Kink‑resistant nitinol for reliable performance: The flexible, shape‑memory nitinol basket resists kinking and maintains geometry over multiple cycles, reducing procedure interruptions from device deformation.
- Supports one‑surgeon basketing techniques: Ergonomic handle and responsive torque control help a single surgeon manipulate the basket while controlling the ureteroscope, aligning with validated one‑surgeon basketing approaches that maintain safety and effectiveness.
- Can reduce overall procedure time: Efficient stone capture and fewer instrument changes can help shorten the basketing portion of flexible ureteroscopy, which otherwise may account for a substantial share of total operative time.
