Abstract: A surgical visualization and medical imaging device and related computer based imaging methods and systems are disclosed. The surgical devices of the present invention use indocyanine green dye combined with a plastic, and are used in enhanced surgical imaging in applications such as robotically assisted surgeries. A near infrared light source, such as an 805 nm laser, may be used to excite the surgical device so that the device emits 835 nm light. Both the excitation and emission wavelengths penetrate tissue and blood, and provide enhanced imaging of surgical procedures. The resulting fluorescence image allows a user to readily determine relative tissue depth, to identify tissue inhomogeneity, to detect masses or tissue irregularities, to pinpoint anatomical holes, and to visualize tears.

Abstract: The tumor stroma, which accounts for a large part of the tumor mass, represents an attractive target for the delivery of diagnostic and therapeutic compounds. Here, the focus is notably on a subpopulation of stromal cells, known as cancer-associated fibroblasts, which are present in more than 90% of epithelial carcinomas, including pancreatic, colon, and breast cancer. Cancer-associated fibroblasts feature high expression of FAP, which is not detectable in adult normal tissue but is associated with a poor prognosis in cancer patients. The present invention provides small-molecule radiopharmaceutical and imaging agents based on a FAP-specific inhibitor.
