Beckman Coulter has received and confirmed reports of an intermittent and unexpected behavior when loading new panels into a WalkAway instrument using LabPro Data Management System version 4.42. The issue could cause workflow interruption with a potential of delaying reporting results due to the inability to begin processing new panels.

The LightCycler¿ 480 algorithm used for the LightMix¿ Zika rRT-PCR Test, EUA (catalog number 07987897001) occasionally (~1% of the time) calls a positive result for a negative sample if there is an inflection point in the fluorescence signal.

Customer complaint was received relating to a LifePak15 device that would power on then power down unexpectedly after a short period of use. When the LP15 powered down, power could be immediately restored by activation of the power button. The device was connected to a cellular modem from MultiTech systems for use with LIFE NET services. The corrective action was completed by Velocitor Solutions in December 2010.

The Drager Pendula spring arm device has a set of screws located on the spring arm that were not properly secured with Loctite and may become loose.

Software anomaly; an issue was found with the proton Pencil Beam Scanning (PBS) dose calculation in RayStation 4.0, 4.5, 4.7 and 5.0. For treatment plans with a combination of range shifter, large air gap and beams that enter the patient surface at an oblique angle, the dose calculation accuracy may be less than expected.

The kits contain Multi-Med Single Lumen Catheters that have a potential for excess material to remain at the tip of the catheter from the manufacturing process. It is possible that the excess material may separate from the catheter during use and pose a potential risk of embolism, which could result in serious injury or death.

The firm received complaints claiming the dental material failed to set up. As the dental material ages, the set time may increase.

Elana has issued this Field Action to voluntarily remove specific serial numbers of our Elana Surgical KitHUD due to potentially compromised integrity of the outer sterile packaging of the Elana Catheter 2.0.

There is a potential for stylet stiffening that is not accurately represented on the labeling. The label states that product includes a stylet with an outside diameter (OD) measuring 0.014, however, the product may contain a stylet with an outside diameter (OD) measuring 0.016.

Medline Industries, Inc. supplies Navilyst with sterile package gloves included in the tandem packing of the Maximal Barrier Nursing Kits. Medline has determined that specific lots of the gloves supplied to Navilyst contain an incorrect expiration date. Navilyst has confirmed that Medlines affected sterile gloves (Medline Part Number MSG1075/MSG3075) have been included in a limited number of kits.

An error may occur with the display of dose computed on images other than the planning CT (auxiliary CT) when using multiple patient cases in RayStation 5. If a CT image set with the same Frame of Reference as the displayed auxiliary CT set exists in another case, the dose display may be incorrect. When the error occurs, the display of dose in patient views, including the maximum dose position, the dynamic isodose lines and the dose grid may be incorrect. The dose value normally displayed in the upper left corner when pointing in the 2D view may be incorrect or missing.

3M is recalling Universal Electrosurgical Pads because a report of an unintended material (process liner) in the product. This may prevent or impede the safe return of electrosurgical current following Electrosurgical Unit (ESU) activation. This defect has the potential to increase the risk of a patient burn directly under the pad or at an alternate site of the body.

There is a potential for stylet stiffening that is not accurately represented on the labeling. The label states that product includes a stylet with an outside diameter (OD) measuring 0.014, however, the product may contain a stylet with an outside diameter (OD) measuring 0.016.

A product issues happens for RF projection images. If user measures on RF image, .cal (Calibration) is not displayed and measurement is not correct. The .cal label is not displayed on the projection images after calibration is performed which should be present if the measurement is presented based on Pixel Spacing.

Firm received reports about "acquisition errors" and the deterioration of material covering the articulating section of the Z6Ms transesophageal transducer.

Incorrect Urea results may be generated sporadically on cobas b 221<6>Roche OMNI S6 system and cannot be detected by QC. QC measurement results can be affected as well. This issue is only detectable if comparison result of a second measurement is available. The cause for this issue is an error in the software measurement procedure. In children, decreased urea results can point at inborn disorders or urea cycle. Therefore, false normal urea values could lead to delayed/incorrect diagnosis of such a disorder. Besides the patients most at risk, the risk for the overall patient population with falsely low or high values is considered remote. No severe adverse health effects are expected; but, unnecessary diagnostic measures may be initiated. Falsely normal results may result in further necessary examination not being carried out, with the possibility of a delay in the diagnosis and treatment. A medical risk cannot entirely be excluded.

The application may crash during the cath lab procedure.

Merit Medical Systems, Inc. announces a voluntary field action for various Merit Medical Procedure Kits due to a compromised sterile barrier.

It was reported by a customer that RadSuite images are not appearing as readable images. This product malfunction has the potential to result in delay in care and a possible re-exposure of the patient to radiation (x-ray).

Siemens determined that discrepant low calcium recovery of QC and patient samples can occur with Dimension Vista¿ CHEM 1 CAL lots 5GM081 and 5GM082.
