A sterile, single patient use, non-absorbable polymer monofilament that is visible on standard radiographs (e.g., X-ray, mammography, CT). It is passed through soft tissue and tied into place during open, percutaneous, or arthroscopic/laparoscopic/endoscopic procedures and standard surgeon's knots or a continuous running outline are used to quickly mark soft tissue for subsequent imaging or for radiotherapy localization.
A sterile 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 formed as a wire, needle, bead, stent-like tube or washer, 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.
