A clip and a bioabsorbable marker are employed to mark a biopsy site. The former provides a permanent marker that is clamped onto tissue and that cannot migrate from the site over time. The latter is gradually bioabsorbed over time but the time may vary widely from weeks to months. In most embodiments, the clip and marker are integrally formed with one another at the time of manufacture. In one embodiment, the clip and marker are independently made but are joined to one another during the site-marking process. The markers are deployed by core biopsy needles of the type employing a vacuum, of the type that does not employ a vacuum, and by coaxial biopsy needles.

A method and device for producing subsurface markings in a transparent material body by focusing a pulsed laser beam in the interior of the material body so that the laser beam exceeds the destruction threshold of the material body to produce a permanent marking. Individual markings form a freely selectable internal engraving as a result of a relative movement between the laser beam and the material body. The laser pulse is varied with respect to its pulse energy (P) by means of a discharge pulse (E) that has an adjustable time delay from an excitation pulse (A). Markings that have varying optical properties depending on the pulse energy (P) are produced in this fashion.
