Description
The Minerva Nitinol Dual‑Function Grasper Basket is a hybrid stone retrieval device that combines grasper‑like control with basket‑style capture to manage stones of varying sizes and complexity in a single endoscopic procedure.
Key features
- Dual‑function grasper–basket configuration to capture, secure, reposition, and remove stones without exchanging devices.
- Nitinol construction with excellent shape memory and kink resistance for reliable opening and closing in challenging anatomy.
- Multi‑functional performance for both intact stones and fragments of different sizes and densities.
- Minimally invasive profile that supports deflection, navigation, and tissue‑sparing access in the urinary tract.
- Compatible with standard endoscopic working channels commonly used in ureteroscopy and PCNL.
Clinical applications
- Endoscopic stone manipulation and removal in the urinary tract through the working channel of a cystoscope or ureteroscope.
- Ureteroscopy for ureteral and intrarenal stones where controlled capture and repositioning are required.
- Percutaneous nephrolithotomy (PCNL) procedures requiring retrieval of fragments from calyces or the renal pelvis.
- Complex stone extractions in tortuous or delicate anatomy where a hybrid grasper–basket can enhance safety and control.
Technical specifications
- Configuration: Dual‑function nitinol grasper–basket for stone capture, manipulation, and release.
- Material: Nitinol basket and core for shape memory, flexibility, and kink resistance.
- Basket diameters: 8 mm and 11 mm to accommodate a broad range of stone sizes.
- Working length: 115 cm for use with standard flexible and semi‑rigid urologic scopes.
- Intended use: Stone manipulation and removal in the urinary tract during cystoscopic and ureteroscopic procedures.
- Usage: Sterile, single‑use device (per product labeling and institutional protocols).
Clinical benefits
- Enhanced control in challenging anatomy: Hybrid grasper–basket design enables direct targeting and secure end‑engaging capture with controlled release, supporting safer management in calyces and narrow ureters.
- Reduced trauma versus rigid devices: Nitinol’s flexibility and atraumatic basket geometry allow opening adjacent to delicate tissue surfaces while minimizing mucosal injury and ureteral trauma compared with traditional rigid graspers.
- Effective capture of variable stone sizes: Basket design and nitinol retention strength support reliable capture of both small fragments and larger stones, consistent with bench data showing strong retention and controlled release for similar nitinol hybrid baskets.
- Support for minimally invasive stone management: Low‑profile, kink‑resistant nitinol construction improves scope deflection and irrigation flow, aiding visualization and facilitating contemporary ureteroscopic and PCNL techniques.
Workflow & efficiency benefits
- All‑in‑one dual‑function device: Combines grasper‑like targeting with basket‑style enclosure, reducing instrument exchanges and potentially shortening overall procedure time.
- Fewer scope removals and reinsertions: Ability to capture, reposition, and release stones with a single device can decrease the need for multiple retrieval tools and repeated scope passes.
- Consistent, predictable performance: Shape‑memory nitinol maintains basket geometry and function over repeated cycles, supporting consistent performance from initial access through final stone clearance.
- Seamless fit into existing workflows: Length, diameters, and compatibility with standard working channels allow easy integration into current ureteroscopy and PCNL sets without major changes to surgeon technique.
