Covidien Provides Update on Voluntary Recall of BIS™ Bilateral Sensors

BOULDER, Colo.--(BUSINESS WIRE)--Jan. 19, 2012-- On November 8, 2011, Covidien initiated a voluntary recall of certain lots of its BIS™ Bilateral Sensors, due to a modification which inadvertently reversed the reference and left eye electrode. This modification could potentially cause a change in the performance of BIS monitoring systems when these sensors are used, resulting in the inaccurate calculation and presentation of processed EEG information for Bispectral Index™ (BIS), Density Spectral Array (DSA), and Asymmetry (ASYM) values.

To date, there have been no reports of patient injury related to the recalled products.

The voluntary recall only affects lot numbers manufactured during a specific period of time. Only BIS Bilateral Sensors from the 58 lot numbers listed below are affected by this action.
