The Madison Mini Bone Biopsy System is a specialized, direct-access 13G tool designed for obtaining samples from small, rounded bones with little surrounding soft tissue. As a compact version of the Madison system, it forgoes a drill, utilizing a perforating cannula introducer with a screw-lock handle that can be entirely removed to minimize exterior weight and size during the procedure. This design facilitates accurate tactile targeting of small lesions. The system includes a clockwise trephine-tip biopsy needle, engineered to retrieve optimized cylindrical samples even from hard, sclerotic, or blastic bone lesions. Its procedural approach aims to reduce soft tissue trauma during access.
