DEVICE FOR PERMANENTLY MARKING A SELECTED TISSUE LOCATION WITHIN A PATIENT'S BODY

摘要

A device for marking a selected tissue location within a patient's body comprises at least two markers pre-loaded into a hollow needle and packaged in a sterile fashion with a stopper to prevent a stylet inserted into the needle from releasing the markers during shipping. An indexing mechanism is also provided for releasably blocking the stylet at successive predetermined levels of insertion into the needle with each level of insertion being associated with the discharge of a single marker.
