MinBasket™ Nitinol Basket – 4‑Wire Tipless

The MinBasket™ Minerva Nitinol Basket is a 4‑wire tipless stone retrieval device designed for flexible ureteroscopy and endourology, combining the security of a grasper with the versatility of a stone basket in a single disposable instrument. It enables efficient capture, repositioning, and removal of urinary tract stones of varying sizes while minimizing trauma in confined anatomy.

Key Features

• Basket design for secure capture, repositioning, and release of stones and fragments in one device.
• 4‑wire, tipless nitinol basket to allow atraumatic engagement close to the mucosa and improved access in challenging calyces.
• Superelastic nitinol construction for kink resistance, shape memory, and reliable opening/closing even at high scope deflection.
• Small French size options to preserve irrigation flow and visualization while sharing the working channel with a laser fiber where applicable.
• Ergonomic handle designed for single‑handed operation, repeated open/close cycles, and precise stone control throughout the case.

Clinical Applications

• Retrieval and repositioning of renal and ureteral calculi during flexible ureteroscopy, including post‑lithotripsy fragments down to approximately 1 mm.
• Access to challenging locations (e.g., lower pole calyces) where deflection, atraumatic manipulation, and sustained visibility are critical.
• Capture and removal of stone fragments and selected foreign bodies in the upper urinary tract when a tipless, nitinol basket is preferred to limit mucosal trauma.

Technical Specifications

• Device: Single‑use nitinol Basket for stone retrieval.
• Basket configuration: 4‑wire, tipless nitinol basket.
• Material: Nitinol basket wires; polymer/flexible sheath; metal/plastic handle (device‑specific).*
• Intended anatomy: Kidney and ureter during flexible or semi‑rigid ureteroscopy.
• Compatibility: Standard ureteroscopes; sizes selected to preserve working‑channel irrigation and deflection.
• Use: Sterile, single‑use device; supplied ready to use in procedure pack.

Clinical benefits

• Atraumatic access in tight spaces: Tipless, 4‑wire nitinol design allows the basket to open right at the base of the calyx, encircle stones, and reduce the likelihood of mucosal damage or perforation.
• Improved scope deflection and visibility: Small‑diameter nitinol basket maintains flexion and irrigation flow during flexible ureteroscopy, supporting access to lower‑pole and difficult calyces.
• Efficient stone capture and clearance: Nitinol basket geometry and flexibility help capture and remove both intact stones and small fragments, supporting high stone‑free rates after ureteroscopic lithotripsy.

Workflow & efficiency benefits

• Fewer device exchanges: Basket style design can grasp, reposition, and retrieve stones of multiple sizes in one device, reducing the need to switch instruments mid‑procedure.
• Reliable opening/closing at deflection: Nitinol’s kink resistance and shape memory maintain basket performance through repeated cycles, even in tortuous anatomy.
• Versatility across cases: Suitable for ureteroscopy, RIRS, and post‑lithotripsy fragment retrieval, giving physicians a single, adaptable retrieval option for most stone locations.
