What is it indicated for?

The Marker System is intended for establishing fixed reference points in patients requiring stereotactic surgery. Examples of situations necessitating stereotaxy could include patients in need of biopsy, resection, lesion generation, implantation of radioisotopes, and small field external beam radiotherapy.

The Marker System can be used as an accessory with all currently marketed Howmedica Leibinger® stereotactic systems and can also be used with frameless navigation systems from other manufacturers.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
