SchurSign Tissue Marker consists of a radiographic soft tissue marker and a delivery system. SchurSign is a sterile, single patient use, discrete marker that is visible on standard radiographs (x-ray, mammography) as well as ultrasound, and Magnetic Resonance Imaging (MRI). SchurSign Tissue Marker is placed into soft tissue during open, percutaneous, or endoscopic procedures to mark a surgical location. SchurSign Tissue Marker is comprised of chitosan filled with Barium Sulfate. SchurSign Tissue Marker delivery system is a distal delivery needle tip, rigid shaft, sterile, and single patient use preloaded delivery system incorporating the SchurSign Tissue Marker. The delivery system consists of a cannula with a handle, a push rod with a plunger, and an end cap. The tissue marker is retained within the delivery system until placement is desired, where it is delivered through the end port by fully depressing the plunger into the handle. The SchurSign Tissue Marker delivery system is used to place the SchurSign Tissue Marker into soft tissue during open, percutaneous, or endoscopic procedures to radiographically mark a surgical location. The delivery system device has a bevelled 12 cm / 14 to 10 gauge needle with 1 cm depth marks and a plunger.
A device intended to be implanted within the body, either temporarily or permanently, to create identifying marks that can be seen on radiographic film or digital images. It is typically in the form of a wire, needle, bead, clip, stent-like tube, washer or fluid, and used to locate and delineate a tumour, lesion, or other site of interest. It is made from materials compatible with the imaging system with which it is intended to be used [e.g., magnetic resonance imaging (MRI), x-ray, or nuclear medicine]; it may be intended for use during radiotherapy procedures.
