Abnormal calibration signals and control recovery issues on the Homocysteine Enzymatic (HCYS) Assay can produce erroneous patient results (positive or negative bias)

To better define the drying procedures described in the IFU to improve the instructions for easier understanding of each drying step after human errors and concerns were identified when completing a Human Factors evaluation of the GIF-1TH190.

A software issue affecting Philips Vue PACS may cause incorrect ischemic map and table value calculations when using the export function in the Perfusion Application for a Siemens CT perfusion study, resulting in misdiagnosis due to incorrect ischemic map and table values.

The Venclose" RF Ablation Catheters may have been manufactured with internal wiring error. The red and yellow signal wires were soldered on swapped ports of the catheter PCB. This error in wire configuration would lead to power being applied through the proximal 3/4th of the heating coil, bypassing the thermocouple, which will then cause the generator to overdrive the catheter in an attempt to reach desired temperature set point. The wire attachment error causes the device to reach temperatures exceeding the levels intended for therapeutic efficacy, while the console is falsely indicating that temperature has not yet been reached, thus increasing the risk of harm due to excessive temperature.

The overlay of visual field test locations on a probability map, as presented in IMAGEnet 6 in the so-called "Hood Report", is not appropriate as it can imply a structure/function correlation for which clinical evidence is not provided

There is the potential for exam files being assigned duplicate Unique Identifiers (UIDs),. If the system receiving the DICOM file (e.g., Picture Archiving and Communication System (PACS)) relies solely on the UID to accept exams, this could lead to a mismatch of the patients identification with their physiological data.

When PET-CT system is executing reconstruction, if PET acquisition for another patient is performed (or PET reconstruction for another patient is performed from raw data processing), PET reconstruction control processing may hang up and PET reconstruction may stop as a result, which may necessitate repeat PET/CT examinations.

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.

Siemens Healthcare Diagnostics Inc. has confirmed that a negative sodium bias may exist in one lot of epoc BGEM BUN Test Cards approximately 2 months prior to expiration. The observed maximum negative bias from internal testing is -10 mmol/L. No positive bias has been observed. Quality Control (QC) fluid may or may not detect the issue depending on the bias magnitude and the frequency of QC testing. One customer complaint has been associated with this issue. No adverse events have been reported. All affected lots have recently expired before the issuance of the recall.

X-ray R/F system software with certain versions of the control board may occasionally fail to display images when switching from Fluoroscopy mode to Radiography mode, which may lead to the possibility of delay or cancellation of the examination.

The High and Low Control acceptance ranges in the Certificate of Analysis (CofA) did not match the acceptance range information on the High and Low Control Component labels. Due to the defect, the device failed to provide results, which may result in a delay in obtaining test results and a remote chance of an adverse health risk.

Due to oximeters not having FDA market approval or clearance to distribute in the U.S.

The patient label stickers may have the wrong expiration date recorded. The contract manufacturer entered the manufacturing date (2024-04-01) as the expiration date. The actual expiration date of the product is 2027-04-01. This is reflected on the carton label and sterile pouch label correctly.

This recall was initiated due to customer complaints of false negative of hCG test results when running patient urine samples. Use of the above listed product lot may result in false negative results. An end user reported that the OSOM Ultra hCG Combo Test, lot 563L13, produced false negative test results from 2 patient urine samples as confirmed by quantitative hCG and ultrasound. During further root cause testing and investigation, an additional 6 devices were found to produce false negative test results from hCG positive samples.

Values used to calibrate whole blood oximeter instruments were observed to be higher than normal, which may result in incorrect patient results where oxygen levels are higher than actual results, which may lead to patient care mismanagement requiring medical intervention.

Epoxy used to seal the edge of the transducer into its paddle exceeded specification. This variability could attenuate the ultrasound signal with a potential impact on the quality of images obtained from the probes.

Due to an out of tolerance tool being used on monitor/defibrillator systems.
