Medtronic Navigation, Inc.-Littleton Recalls

Hazard: Potential for an electrical component of the O-arm" O2 Imaging System to intermittently shut off,failure can cause the potential for surgical delay, additional imaging, cancellation and rescheduling of surgery, or completion of surgery without the benefit of image guidance.

Hazard: Ground cable installed incorrectly.

Hazard: Due to a manufacturing issue affecting particular O-arm" O2 Imaging Systems, Medtronic has determined that the gantry tractor motor drive belt may loosen over an extended number of uses at a higher frequency in these systems. If the belt loosens, it may result in rotation of 3D images about the gantry isocenter. While the 3D image is anatomically accurate within the image itself and may be used to confirm therapy, its electronic registered location may be rotated relative to the actual physical position of the patient.

Hazard: The 0-arm 1000 Imaging System uses energy from the batteries to generate X-rays and move the system. If a charger board is not functioning properly, the batteries will not receive a full recharge of the potential capacity and results in the inability of the system to take X-rays, open the gantry, and move the system from one place to another, which may affect the ability to continue use within the operating room until the charger board and/or the batteries are replaced

Hazard: O-arm 02 Imaging Systems correction to software version 4.1.0; new version of the user manual and an Image Acquisition System ("IAS") product label; replacing blown fuse of the new AC power input circuit

Hazard: Software anomalies were reported to affect the following system functionalities: startup and shutdown, system and network communication, motion control, image acquisition and output, dose reporting, and logs generation. Software version 3.1.7 will be installed on all 2nd edition imaging systems.

Hazard: Software update ("SW Update 3.2.1") is being implemented to address the following issues: Inability to power the system after shutdown, System stays in standalone mode, Image reconstruction, System/Pendant bootup, Dose display/report, Gantry motion, Network communication, System shutdown, and Early termination of 3D spin.

Hazard: During servicing of certain internal components of the O-Arm O2 Surgical Imaging System, it is possible that the high-power cable connector may come in contact with surrounding metal during the disconnecting/reconnecting process which may result in an electrical short and a shock to the field service technician.

Hazard: O-arm O2 Surgical Imaging System Spatial calibration may be erroneous in Stealth Station navigated images

Hazard: Review of on-system electronic product labeling and Instr uctions for Use in response to an internal management concern uncovered gaps in compliance with the requirements for information to be provided to users in 21CFR part 1 020.30(h).

Hazard: It has been discovered that replacement x-ray generator and system motion batteries could become damaged during shipment, resulting in unacceptable risk of failure.
