FHC microTargeting Guideline 4000 ver 1.4 (GL4K) Software, Catalog # MT-GL4K. Intended to assist in functional neurological procedures.

The raster tab for the GL4K version 1.4 software may assign incorrect depths for waveform recordings and if used to identify the implantation target for the DBS lead, the implant may be placed in the wrong location.

FHC notified customers by telephone and by an Urgent: Medical Device Correction email, dated December 2009, beginning December 28th. Customers have been instructed to keep the instruction with the GL4K until FHC can provide a revision to the software; and, to use only "distance from zero" or "distance traveled" modes (not "distance from target" mode) during procedures using the raster tab. Customers are to notify their FHC representative to confirm receipt of the notification. A software patch has been verified and validated and will be installed on all affected units. The new version of the corrected software is Guideline 4000 version 1.41. Questions should be directed to Jason Moyer, product manager or Keri Seitz, recall coordinator at 207-666-8190.
