With the PARAGON®, bone marrow aspiration can be performed immediately after the bone marrow biopsy in a single maneuver, which is especially gentle for the patient and ensures optimal sample quality. The unique integrated sample collection mechanism allows for minimally invasive retrieval without bone dislocation, making the procedure less painful and ensuring easy and quick handling. The ergonomic handle with color coding ensures precise and controlled operation and simplifies the identification of needle sizes (gauge).
