    Product information

    Product details at a glance:

    • Correctable localisation system for the preoperative marking of non-palpable, suspicious breast lesions
    • New and highly compact application system
    • Provides flexibility and maneuverability in constricted interventional situations, for example when using 2D biopsy compression plates with holes, this compact application system is very useful.

    Marking wire

    • Easy repositioning can be achived by simply pulling back the wire into the cannula
    • Twisted Nitinol double wire with distal double arches and extremely sharp bevelled wire tips ensure a firm anchorage in the tissue
    • Variably tight twisting of the wire serves as depth markings for the surgeon and provides information on the distance to the tumor center
    • Good visibility during mammography and ultrasound thanks to the special material and surface quality, as well as the arched shape of the marking wire
    • Highest stability of form and resistance to pressure together with simultaneous flexibility
    • Enclosed fixation part enables secure fixing of the wire after application

    Puncture cannula

    • Optimal visibility under mammography, ultrasound and MRI
    • Depth markings on the cannula shaft enable orientation during the application
    • Particularly sharp and atraumatic due to the faceted bevel
    • Good gliding features due to the cannula coating

    Packaging Unit: 10 pieces

    The SOMATEX® Duo-System Stereo is intended as a preoperative marker of non-palpable suspected breast lesions to facilitate the intraoperative localization by the surgeon. The Duo-System Stereo consists of the puncture cannula and a preloaded marking wire with a distal double arch.

    New and highly compact application system

    New application system with a highly compact design provides flexibility and maneuverability in constricted interventional situations. This system is very helpful while using 2D biopsy compression plates with holes.

    Marking wire
    The marking wire is made of a twisted double wire made of Nitinol with a double-arch shape. The tips of the double arches are extremely sharp-bevelled and ensure a firm anchorage in the tissue (double-loop technique). The shape of the double arches allows for the smooth withdrawal of the marking wire of the Duo-System Stereo into the cannula and its re-release to carry out a positional correction if necessary. Markings on the wire provide information as to whether the wire is located inside or outside of the cannula. Furthermore, the significantly tighter twisting at the head of the marker wire functions as depth marking and facilitates the intra-operative localisation of findings for the surgeon.

    Puncture cannula
    The puncture cannula of the Duo-System Stereo is equipped with a sharp bevelled edge. Subsequently, the penetration of the skin is particularly atraumatic and patient-friendly. The cannula shaft has been provided with centimeter markings to allow for depth orientation. Due to its coating the puncture cannula of the Duo-System Stereo has good lubricating features.

    The Duo-System Stereo is delivered sterile and in a preloaded condition, including a fixation part to avoid dislocations and is ready for immediate use.
