StoneMaster is an innovative stone retrieval system designed to comfortably, safely, and quickly extract concretions of various sizes—particularly from hard-to-reach areas in the renal pelvis. Its unique three-arm nitinol basket leverages hybrid functionality, combining the benefits of both a grabber and a stone extraction basket, ensuring fast stone capture and atraumatic removal even from the distal ureteral or calyceal system.
Perfect Hybrid of Grabber and Basket
Elastic, Fully Articulated Three-Armed Basket: Seamlessly toggles between a basket configuration (for encasing the stone) and a grabber approach (for direct grasping), giving clinicians heightened procedural flexibility.
High-Performance Nitinol Construction
Shape Memory & Flexibility: Nitinol wires retain stability while allowing the basket to open and close smoothly in the confines of the renal collecting system.
Durable & Kink-Resistant: Ensures consistent performance during repeated captures, even in tortuous ureteral or calyceal anatomy.
StoneWrapper Integration
Three-Arm Hybrid Head: Combines direct basket function with a specialized grabber tip—encasing stones quickly while minimizing risk of trauma.
Advanced Guide Wire Technology: High shaft stiffness with a hyperflexible distal end streamlines catheter manipulation and stabilizes the StoneMaster device in challenging angles.
Tuohy-Borst Adapter & Insertion Aid: Simplifies introduction into the working channel of flexible ureteroscopes and acts as a splash guard—maintaining a clean and safe workspace.
Multiple Sizes & Opening Options
Two Basket Diameters: Adaptable to various stone sizes or anatomical variations encountered during retrograde intrarenal surgery (RIRS).
Varied Opening Mechanisms: Operators can choose from standard or larger opening designs, tailoring retrieval method to stone burden and location.
Clinical Advantages & Applications
Efficient Stone Extraction
Direct Removal of Marginal Stones: Ideal for capturing even small or “slippery” concretions lodged in difficult angles of the renal pelvis or lower calyx.
Rapid & Reliable: Shortens procedure times, reducing anesthesia requirements and enhancing patient comfort.
Improved Patient Safety & Comfort
Atraumatic Basket Action: The nitinol arms gently enclose stones, diminishing the risk of mucosal damage or bleeding.
Minimized Device Exchanges: The hybrid design (grabber + basket) lessens the need for switching instruments mid-procedure.
Optimized Visualization & Control
Excellent Irrigation: System design fosters clear endoscopic viewing, ensuring the operator can locate and remove stones effectively without losing vision.
Stable Handling: The ergonomic push handle and stiff/hyperflexible guide wire synergy reduce operator fatigue, enabling consistent performance through complex manipulations.
Flexible & Versatile
Lower Pole & Multi-Calyx Access: StoneMaster’s sinusoidal and pigtail expansions adapt to varied angles, addressing branched or angled calyceal anatomies.
Compatibility: Integrates with most standard flexible ureteroscopes, enabling universal adoption for renal stone retrieval.
