Near-infrared fluorescent surgical dye markers

摘要: The potential use of a PMMA encapsulated near-infrared fluorescent dye includes endoscopic tattooing intestinal neoplasms, location visualization non-palpable breast lesions, and, but not limited to, location/visualization soft tissue lesions in difficult anatomic regions. Commercially available imaging systems, both open and laparoscopic, would be used conjunction to fluoresce these marked tissues, augmenting the surgeon's ability intraoperatively locate correct lesion resect.
