  • Medical tissue-marker and manufacturing method for the same
    Patent number: 10022459
    Abstract: A medical tissue-marker which enables the identification of a location even from the outside of an organ, can remain topical over a long period, and enables the easy identification of a marked location within the whole organ; also a manufacturing method for the medical tissue-marker. The medical tissue-marker includes a vesicle formed by the synthesis of a phospholipid and a near infrared fluorescent dye, and an emulsion formed by the synthesis of the phospholipid and an X-ray contrast medium, and has agglomerated clusters wherein the vesicle and the emulsion are contained in a hydrophilic solvent and a plurality of capsules are formed by use of an emulsifier.
