Medical Devices Recalls

Medtronic neurostimulators (used with pain and deep brain stimulation therapy) have a cycling feature that, when enabled, allows stimulation output to be toggled on and off based on the programmed settings. The use of this feature is determined by the physician and set using the clinician programmer. Current labeling indicates the use of cycling improves device longevity and recharge interval

Extremely low absorbance readings.

GE Healthcare has recently become aware of a potential safety issue with certain GE MRI Products. Patient egress from the system can be delayed or impeded if the cradle release handle and/or cradle release block mechanism malfunctions or becomes misaligned. This could make the safe removal of the patient from the system difficult.

There are two situations that may occur when using the GemStar Docking Station, List Number 13075-XX-XX, in conjunction with the GemStar infusion pump: 1) when the Docking Station is used in conjunction with a GemStar Phase 3 pump (List 13000-XX, 13100-XX, or 13150-XX) the potential exists for the GemStar Phase 3 pump to fail to power up while connected to the Docking Station, and 2) when either a GemStar Phase 3 (List 13000-XX, 13100-XX, or 13150-XX)or GemStar Phase 4 pump (List 13086-XX, 13087-XX, or 13088-XX) is used in conjunction with both a Docking Station and an External Battery Pack accessory (List 13073-XX) there exists a possibility that the GemStar pump will display error code 11/003 and give an audible alarm indicating excessive input voltage from the external sources. If the GemStar pump detects what is perceived to be more than 3.6 Volts measured on the external voltage input, the pump will stop the infusion and alarm both with an audible sound as well as a visual alarm.

Manufacturing of these devices with a grade of stainless steel that is not within specifications.

Ortho Clinical Diagnostics (OCD) confirmed the potential for lower than expected C-Reactive Protein (CRP) results only to be generated when using VITROS Chemistry Products Specialty Diluent (Lot F3168) or VITROS Chemistry Products FS Diluent Pack 3 (Lot 01-3266). The VITROS Instructions for Use states that if the if a C-reactive protein concentration exceeds the systems measuring (reportable or dynamic) range, dilute the sample with VITROS Specialty Diluent or a patient sample containing a low concentration of CRP. An initial threefold dilution is recommended. Internal testing determined that results using VITROS CRP Slides have the potential for approximately 51% bias using a 3x dilution factor.

A customer reported the presence of an organism in a lot of Calcium Alginate Fiber Tipped Wood Applicator Swab.

Siemens Healthcare Diagnostics confirmed over-recovery of samples with concentrations greater than 5.5 ng/mL with the IMMULITE/IMMULITE 1000 and IMMULITE 2000/IMMULITE 2000 XPi Androstenedione assays (LKAO1, L2KAO2). Siemens has determined that these lots are linear up to a concentration of 5.5 ng/mL, instead of 10 ng/mL as stated in the Instructions for Use (IFU). Quality Control materials at concentrations between 5.5 and 10 ng/mL will detect this issue.

Two lots of Anti EpCAM PE-Analyte Specific Reagent are mislabeled - the actual antibody present in the vial is CD9 PE.

Slippage of the radius drive belt in the relative 180 degree orientation of the superior positioned detector head will allow the detector head to drift down and potentially come in direct contact with the patient.

If screws are not properly tightened with a torque wrench they may become loose over time.

Siemens confirmed an overall average positive bias of 23% against the WHO 2nd IRP 75/502 with the IMMULITE Systems Total IgE assays.

When using multiple radiation treatment targets within a single plan, the ExacTrac v.6.0.3 might position the patient to an unintended radiation treatment point. As a result, there is a possibility that the radiation treatment dose may be delivered to the unintended target position.

Certain lots of Acumed Tension Band Pins are being recalled because the implantable product was manufactured with a grade of stainless steel that is not within specifications.

The reciprocation mechanism in the PolypVac Microdebrider may turn off prematurely due to a component failure in the device handle.

Quality Control materials at concentrations between 5.5 and 10 ng/mL will detect this issue.

Some 23 kHz Torque Wrenches were incorrectly assembled and contained a 36 kHz Hex Wrench Insert instead of the 23 kHz Hex Wrench Insert.

A reagent contained within the product may return false negative results.
