Neurological Stereotaxic Instrument（HAW）

Locking mechanisms may not properly secure to the Arc system, resulting in shifting of coordinates during procedures.

When the device is activated during surgery, the device software issues an error message "Instrument Face Mask (6001385000000) is not valid for this application" resulting in an inability to use the device.

Due to increased risk that paint flakes from the engravings may separate from the device and there is the possibility that the flake may inadvertently enter the wound

A complaint was received (MDR 3002250546-2024-00003) prompting an investigation. The investigation revealed a schematic for a spacer tube which is too long relative to the size of other components was included in the build order for Lot 244517 of P/N 66-IT-06P. Use of the product with a spacer tube which is too long could result in intercranial hemorrhaging and brain damage.

Elekta has become aware that Disposable Biopsy Needles can contain some microscopic debris on the inside of the biopsy needle. The material in the debris is stainless steel, same material as the biopsy needle. No debris has been found on the outer parts of the biopsy needles.

Due to a software issue, there is the potential for a missing digit, letter, or decimal in either the "distance to target" or "tip stop point" display during navigation.

Elekta has become aware that Disposable Biopsy Needles (911933) from one batch (837838839) can contain some microscopic debris on the inside of the biopsy needle. The material in the debris is stainless steel, same material as the biopsy needle. No debris has been found on the outer parts of the biopsy needles. The sterility of the biopsy needles has not been affected. This issue has been reported from one site.

Defective Skull Anchor Key. After attachment of the single use Skull Anchor Key to the patient, the user was unable to attach the CT Localizer to perform stereotactic Imaging. Attachment of the localizer is typically accomplished by fully screwing in the four thumbscrews of the localizer into the threaded holes found on the top surface of the Skull Anchor Key.

Sterile-packed Cranial Drills may not be sterile due to a breach in the packaging and/or may have discoloration near the drill tip.

Due to a software anomaly which potentially could result in the surgical planning data shifting to an unintended location.

In nonaxial/some axial exams if surgical plan utilized, Target Guidance selected, tip projection utilized, Navigate Projection enabled, software anomaly may occur during tumor resection/shunt placement/deep brain stimulation, where distance to/past target text no longer synchronized with navigation information, inaccurate value displayed; may result in prolonged/additional procedure, tissue injury

During non-axial/some axial exams, software anomalies occur during procedures affecting depth gauge graphic displays for cranial biopsy; causing displays to no longer synchronize with other navigational information showing inaccurate values, which may result in prolonged/additional procedure, tissue injury

The incorrect IFU was distributed with the devices.

Due to increasing complaint trend for the Non-Invasive Patient Tracker system where complaints analysis indicates that users are unable to successfully verify their navigation instruments during image-guided surgery.

Cranial biopsy procedure software can enter a state where the biopsy depth gauge is no longer synchronized with the rest of the navigational information on the screen and may display an incorrect position of the biopsy needle, which may result in prolonged procedure, the need for additional surgical procedure, tissue injury.

A tracker that holds and guides neurosurgical surgical instruments may be subject to separation/weld failure, where the tracker connects to the instrument tube. If a weld separation occurs and a navigation inaccuracy is experienced, it may result in prolonged procedure and tissue injury. Per 11/24/21 firm email: The Bundle Autoguide Reg Kit does not have a model number. The Bundle Autoguide Reg Kit is internal terminology and not visible to the customer and are used as sales and shipping configuration only. When this sales bundle is chosen by an internal Medtronic Sales Representative the devices included in the bundle are individually packaged and labeled and sent to the customer in a single shipment. The devices included in the bundle are ordered, packed, and shipped as individual medical devices with unique model numbers, which is the reason that the Autoguide Tracker (28248) and the Stealth Autoguide Basic Instrument Kit (9736188) are the only part numbers subject to this FCA.

The firm has become aware of a software anomaly affecting ROSA One 3.1 Brain application which led to the inaccurate placement of an electrode during surgery. The firm has received 3 global complaints related to the issue. An incorrect trajectory could result in serious injury or death if undetected during surgery.

There was an increase in complaints related to tip breaks and wobble/vibration.
