VectorVision (VV) Sky Navigation Platform (19" Computer Rack); the 19" computer rack is a component of the VVsky Vario, BrainSUITE iMRI, BrainSUITE NET and BrainSUITE iCT systems; BrainLab AG, Kapellenstrasse 12, 85622 Feldkirchen, Germany Intended to be an intraoperative image guided localization system to enable minimally invasive surgery. Indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where a reference to a rigid anatomical structure can be identified to relative to a CT, CTA, X-ray, MR, MRA and ultrasound based model of the anatomy.

Diameter of cables used for installation are to small for the applied current. If an internal short circuit is produced the medical power supply will not shut down automatically and will continue to deliver current, which could result in overheating cables.

BrainLAB sent Product Notification letters dated 11/12/07 to their VectorVision Sky end users, informing them of the possible overload of electrical cables in VVsky products with Data Billboards and/or microscope integrations and/or Device Connections Panels (Wall Panels). The users were requested to perform an inspection of the medical power supplies and cabling on a regular basis. If anything suspicious is noted, they were directed to shut down the entire system and contact BrainLAB immediately. BrainLAB contacted each account shortly after the sending of the letter to arrange for the installation of small fuses/circuit breakers according to the specific load limits per device, which will open the circuit in case of overload on faulty circuits, and to exchange the low voltage cables that directly connect the medical power supply from 1.5 mm2 to 2.5 mm2 thickness to withstand the full 20 amp current in case of a failure. Any questions were directed to BrainLAB's customer hotline at 1-800-597-5911.
