To reinforce existing instructions within the Directions for Use (DFU) and provide further guidance which will be added to the DFU that may reduce the likelihood of metal cap and fiber tip break temperature related complaints.
When a user acquires XperCT scan on an Azurion 2.0 system, enters the XperGuide guidance step and moves the L-arm away from the initial scan position before starting the live guidance, a warning message directs the user to move the L-arm stand back to the initial XperCT scan position. Although the software generates this message, it does not prevent the use of live guidance if the L-arm stand is not repositioned. Using live guidance with a mispositioned L-arm can result in the display of an incorrect overlay and needle path.
Potential issue with the manufacture and inspection of U-channel sheaths in Implantation Instruments Sets. Affected U-channel sheaths may be more likely to cause damage to ProACT implant devices when passes through the sheaths.
Registering dose and structures in the treatment delivery workflow could result in an alignment discrepancy between the imported previously delivered dose and the displayed patient anatomy and structures. The MRIdian TPDS software shows this misalignment to the user in the predicted dose-volume histogram (DVH). The misalignment impact may not be obvious to the user. During plan re-optimization the previously delivered dose would be incorrectly accounted for by the software. This may result in unexpectedly higher or lower dose than the intended dose calculated for the subsequent treatment plan. When this occurs in the treatment planning workflow, the registration fails to align the dose with the image and the user is unable to proceed.
During the sterilization of radial compression devices, some of the inflatable balloons may break or burst, which may result in air leakage and the inability to maintain pressure/compression. This may result in a lack of hemostasis resulting in bleeding or a delay in treatment; the defect is likely to be visually identified by the clinician before use or identified during inflation of the balloon.
The vertical dimensions of screw-hole position in some standalone cages might be out of range in engineering drawings. A possibility exists of screw pullout, lossening, instability, or less bone-screw engagement than intended by physicians.
A faulty locking piece of the Instrument Carrier that does not fulfil the requirement of locking force to the Arc has been found during an internal check of a Leksell Vantage Stereotactic Arc System.
Certain iLab Polaris Systems which were upgraded with a previous 2.10 software version (disk batch 629774) contained a bug in which only the True Color Secondary Capture (SC) format will archive Diastolic Hyperemia-Free Ratio data as intended. If either Multi-Frame UltraSound (US) or SC Image Storage formats are used, the DFR data will not be archived and the user will not be notified of this unexpected behavior.
