Siemens Medical Solutions USA Recalls

Hazard: Some Artis zee ceiling systems show an increased abrasion of the cabling at the cable outlet of the inner C-arm, the limited functionality may not be sufficient to continue with treatment as planned. This may result in a situation where it is necessary to cancel clinical treatment or to continue treatment on an alternative system.

Hazard: Due to the configuration of certain Windows Service Permissions within the operating systems of the Sensis/ Sensis Vibe computer, there is a risk for exposure of sensitive information, manipulation of data, or Denial of Service attacks and could result in incorrect diagnostic or therapeutic decisions

Hazard: A patient image was assigned to a different patient during image recovery process. In the unlikely event of interrupted connection to a MAX detector during initiated image recovery, instead of the currently acquired image, previously acquired image (potentially image of the previous patient) may be displayed to the user, potentially impact diagnosis of the patient examined when the connection was interrupted

Hazard: The ultrasound system averages the Mean Sac Diameter (MSD) and Gestational Sac Diameter (GSD) into the Estimated Date of Delivery (EDD) calculation. This may result in an incorrect EDD, which may influence patient management decisions regarding induction of labor and elective caesarean delivery, which may result in premature births.

Hazard: Siemens has become aware of a potential issue in which the imaging system UPS sporadically forces a shutdown of the imaging system PC without a true power supply problem.

Hazard: SOMATOM systems-issues in with software syngo.CT VA30A_SP2 or syngo.CT VA30A_SP2a, may result in sporadic problems causing scanning workflow interruptions and unexpected user notifications. Delay in diagnosis or patient rescan may occur. Sporadic software errors during interventional workflows may also result

Hazard: System may sporadically freeze (lock-up) during operation or while being in an idle state, no longer possible to interact with the system

Hazard: Misleading error messages and a gap in the Operator Manual which affects ARTIS Icono biplane or ARTIS Icono floor systems with software version VE20B. Potential issues include System error management, Erroneous error messages, Zoom/Pan Function, Grid Indication, and Coolant Level. May cause procedures to be terminated and performed on an alternative x-ray system

Hazard: After the March 2019 corrective action on the monitor support arm, there is a residual risk of the support arm becoming dislodged in cases when the monitor support arm is used intensely over a long period of time.

Hazard: After the March 2019 corrective action on the monitor support arm, there is a residual risk of the support arm becoming dislodged in cases when the monitor support arm is used intensely over a long period of time.

Hazard: System does not trigger a cancel command followed by a reload of the scan with the new parameter(s). This issue may result in a delay in diagnosis and/or need for patient rescan

Hazard: When the user changes frame rates from lower frequency (e.g. 10 f/s) to higher frequency (e.g. 30 f/s) during continuous release of Fluoro "Fluoro Override", the measured Air Kerma Rate can exceed the regulatory limits.

Hazard: Some electronic components within the generator were equipped with an incorrect protection diode. As a result, protection against overvoltage may be inadequate, and the system may not function properly in the event an overvoltage situation occurs.

Hazard: There is a software problem which affects the DSA Roadmap application on ARTIS Icono and ARTIS Pheno systems with software version VE20B. In rare cases, when the DSA acquisition has been started while the C-Arm or table is moving, there may be a shift between the image acquired at the start position and the image (i.e. DSA vessel map) taken at the reference position. This may lead to a DSA vessel map being overlaid to a subtracted fluoro image at a position that is not accurate.. However, if the displacement is slight or at an unfavorable plane, the user might rely on incorrect visualization of the catheter relative to the vessel map. This could imply danger to the patient.

Hazard: Potential malfunction in which the examination room monitor may become intermittently dysfunctional (e.g., no display/flicking/wrong resolution).

Hazard: Potential exists for the collision supervision not to work properly following loss of the individual room configuration data settings causing danger of collision with fix mounted room equipment, walls or floor may occur. This might cause components of the system to fall or tilt which could result in crushing of patients, operators or staff, collision of system parts with patients, as well as result in delay or interruption of the clinical procedure

Hazard: Due to adverse events received by the firm for left atrial perforations and Atrioventricular Node block.

Hazard: Sporadic problems with the current software may result in scanning workflow interruptions and unexpected user notifications causing delay in diagnosis or patient rescan

Hazard: Calibration offset between the central CT image plane and the external RT lasers has been set automatically to the factory default of 50.00 cm, if the misadjustment of the offset value is not recognized during the subsequent treatment planning process or remains undetected during the position verification at the treatment system (e.g. linear accelerator), this can potentially result in an incorrect dose or dose applied to the wrong location

Hazard: This letter is to inform you of the possibility that your Symbia S or Symbia T system(s) may have unintended slow motion of the detectors in specific situations which could pose a potential risk.

Hazard: The connector linking the EtCO2 module to the HemoBox may break and become damaged, if the connector is re-attached to the HemoBox in this damaged state, under certain incorrect pin alignment conditions, the HemoBox may stop functioning and all vital signs are lost

Hazard: E. CAM and Symbia system with foresight detectors performing gated or dynamic acquisition may lose some detector time information. Our risk analysis indicates that the probability of occurrence is remote. SPECT: To detect or image the distribution of radionuclides in the body or organ, using the following techniques: planar imaging, whole body imaging, tomographic imaging for isotopes with energies up to 588keV. CT: The CT component is intended to produce cross sectional images of the body by computer reconstruction of x-ray transmission data from either the same axial place taken at different angles or spiral planes taken at different angles. SPECT+CT: Perform CT scans and nuclear imaging studies within the same instrument. To obtain attenuation corrected images and to provide registration of anatomical and physiological images within the patient's anatomy.

Hazard: Siemens has become aware of a hardware error which affects Cios Spin and Cios Alpha systems after the previous repair of the X-ray Generator with an integrated Energy Storage Unit (ESU).

Hazard: Siemens has become aware of a hardware error which affects Cios Spin and Cios Alpha systems after the previous repair of the X-ray Generator with an integrated Energy Storage Unit (ESU).

Hazard: Hardware error- Hot Plugging feature could cause an electrical malfunction on the main control D80 (below revision 04 installed) of the generator which is part of the main unit (c-arm) and cause permanent loss of imaging functionality.

Hazard: Two software issues (1) Using the override function in case of blocked system movements affecting Luminos dRF Max, Luminos Agile Max and Uroskop Omnia Max systems may cause collision of the system under operator control with obstacles or persons .(2) Incorrectly assigned image affecting Ysio Max, Luminos dRF Max and Luminos Agile Max systems with detector MAX Static causing incorrect base for diagnosis

Hazard: If the user modifies for any reason (e.g. reduction of artifacts) the original image orientation of a standard MR protocol to acquire images in a different orientation for further processing in Synthetic CT , the software does not recognize the adapted acquisition plane. This may result in images with wrong geometry. When this distortion remains unnoticed and the images are subsequently exported to a treatment planning system (TPS), an incorrect calculated radiation treatment plan cannot be excluded. The occurence of this issue is very unlikely and has never been reported so far.
