Medical device recalls

For the automated multi-image-acquisition procedure Ortho x-ray collimation is set in a preparative stage for the entire examination area prior to the exam. During acquisition of each individual x-ray image, the x-ray collimator is automatically positioned in a way that the subsequent series of acquisition covers the defined field of view needed for each step. However, during the acquisition the collimation area displayed to the operator on the User Interface does not correctly represent the collimation area specified by the system. It indicates to the user an open collimator instead, e.g., the information displayed on the User Interface shows wider area of collimation than values preset prior to the examination. However, the collimation of the x-ray is performed correctly and always matches the examination area predefined by the user.

New or replacement insulin pumps are not pre-programmed with basal rates or other verified settings (bolus wizard settings, sensor settings, etc.), which must be set up and saved on pumps prior to use. Patients who do not realize this will receive no basal insulin, which can lead to insulin under-delivery. Insulin under-delivery can cause severe hyperglycemia, which may lead to diabetic ketoacidosis. Current device labeling does not clearly identify that these insulin pumps are capable of functioning with the default basal setting of 0.0 units/hr for all 24 hours and that no error message will appear if the default basal setting remains active. Furthermore, the labeling for the affected devices does not highlight that saving the basal settings requires multiple steps and failure to complete all steps will not save the new basal settings, nor that the steps required to set and save a basal profile and other parameters which are used as part of the bolus calculator function are different.

There is a potential that the DNA sequence analyzer may short circuit shortly after disconnection and reconnection of circuit board or imaging module due to an insufficient reconnection of the ribbon cable. The short circuit results in the device being inoperable.

The drill and adjustable drill guide can jam/bind intraoperatively resulting in the drill guide breaking.

The Hanger-Bar is being recalled due to the potential for the set screw loosening as a result of a manufacturing issue (failure to apply Loctite adhesive). As a result of the set screw loosening, there is the potential for a fall hazard.

Incorrect source to skin or surface distance (SSD) calculation may result in dose error when using RayStation system.

An issue where the combined density in a dose grid voxel partially covered by the External ROI and also partially covered by an ROI of type Bolus, Support or Fixation may be unexpected.The density in the voxel can be both under- and overestimated

If the dynamic jaw mode is used and an optimization is continued after changing the dose grid or modifying the target ROI, the positions of the jaws may change unexpectedly for some control points. User must be aware to avoid unnecessary jaw openings during treatment planning

Shelf-life for the 8244 Pneumonia (33 Targets) Control Panel determined to be 6 months instead of 18 months.

Potential product mix where the size and/or offset of the Biolox delta Ceramic V40 Femoral Head inside the package does not match the package labeling

Siemens Healthineers has identified a software error in previous software version VB10 for the Ysio fully automated system. The unit may process incorrect internal values for the position of its ceiling tube stand. If the user activates a longitudinal or transversal movement at the time of the error, the system controls may initiate a correction of the tube stand position, resulting in an unintended movement. If the described error occurs, a potential for collision risk for objects or persons in the vicinity of the moving stand exists. This may result in minor to serious injuries to persons.

Transport company failed to stop at the border for required FDA inspection.

Recalled devices were packaged in convenience kits.

The photomultiplier tube, may have compromised functionality in some instruments. As a result, the user is likely to observe an increase in false-positive or indeterminate results.

The StO2 values may be inaccurately low when using either the FORE-SIGHT ELITE Tissue Oximeter Module or the FORE-SIGHT ELITE Absolute Tissue Oximeter Monitor with the Fore-Sight Elite large sensor in certain somatic locations (arms and legs). While the StO2 absolute values are impacted, the directional trend remains accurate, but may have a larger magnitude change. Low StO2 values may lead to unintended or inappropriate treatment

The finished device package did not contain the IFU.

An unreleased Version 4 Protocol Library was installed on Nimbus PainPro (H) infusion pumps in error that may impact patient safety if used on patients.

Devices distributed lacked regulatory clearance.

Dimension Vista Magnesium Flex reagent cartridge lots exhibiting imprecision and intermittent Abnormal Assay flags. When this issue occurs, there is a potential for QC failures or erroneous patient results which may lead to repeat and follow-up testing.

An incorrect center bolt was used in the assembly of the product which could result in a patient fall during use.

Roche has identified a small number of cobas Liat analyzer units that have consistently high noise levels (background signal) originating from the amber detector (used for Influenza B detection). This noise increases the probability of false positive Influenza B results.

Malfunction of the hand pendant controlling movement of the therapy couch and nozzle may result in unintentional motion. Patient injury is possible if they come in contact with the nozzle or other objects in the treatment room.

Retinal analysis system software has some features, based on artificial intelligence, that potentially lack appropriate market approval, so it is recommended to use a specific prior software version.

Instructions for Use (IFUs) updated to include use of a headband is now recommended for all patients and instructions for the application of the headband. Additionally, IFU updated to include warnings for risk of condensation build up depending on environmental conditions with instructions.
