Abstract
An apparatus for marking a location within the tissue of a patient includes an optical fiber whose forward end illuminates to facilitate localization of a target tissue by a physician. A strain relief tube is disposed around the outer diameter of the optical fiber adjacent the forward end of the optical fiber. An anchor means, such as a pair of hooks, is mounted to the strain relief tube for engaging the tissue of a patient to secure the tip of the optical fiber within the tissue of the patient. The anchor means is deployed to anchor the tip of the optical fiber in the vicinity of a location desired to be marked. The rearward end of the optical fiber is optically coupled to a light source to transmit light through the optical fiber to illuminate the tip, thereby to facilitate a physician in visually locating the tip.
