    The SOMATEX® Coaxial MR Puncture Cannula is especially suitable as sheath for multiple sample collection of soft tissue with the MRI Biopsy Handy. It is also ideally suitable for initial punctures, as a sheath for catheters and guide wires and can be used as an injection and drainage cannula.

    Puncture sheath
    The cannula is made of a special non-magnetic metal alloy that allows for problem-free use in magnetic resonance tomography. The cannula tip is circular and blunt. A pencil-tip mandrin is located inside. The cannula shaft is equipped with centimetre marks to guarantee optimal depth orientation during use.

    Pencil-tip mandrin
    The pencil-tip mandrin is equipped with a particularly sharp trocar grinding, offers very good visibility under MR imaging and is distinguished in use by a particularly low puncture trauma. In addition, it provides great cannula stability and is particularly atraumatic.
