Masimo sent an Urgent Voluntary Medical Device Recall letter dated December 21, 2010, to all affected customers via FexEx on December 23, 2010. The Urgent Voluntary Recall Notice provides instructions on the actions that the customers and field personnel must take to correct the issue. Customers were instructed to choose any of the three options below. Option 1 would ensure accurate results are achieved when using the Pronto-7 rainbow 4D Reusable Sensor with the Pronto-7 Spot Check Pulse CO-Oximeter. (1) Option 1: Prior to performing an SpHb measurement, wait at least seven (7) minutes with the patient's finger inserted inside the Pronto-7 rainbow 4D Reusable Sensor. The seven minute wait will help ensure that the actual finger temperature and the sensor temperature are close to equalized. Masimo is working to quickly develop a revision to the Pronto-7 rainbow 4D Reusable Sensor that will address this issue and plan to have it available in early 2011. We will contact you when the new revision of the sensor becomes available to replace the current sensor; (2) Option 2: Return only the Pronto-7 rainbow 4D Reusable Sensor and request a loaner Pronto device with rainbow DCI sensor (part numbers 9167 and 2646) to be utilized until the new version of the sensor is available for use with the Pronto-7. Please let us know if you wish to try the Pronto or see the product brochure for Pronto. We will contact you when the new revision of the sensor becomes available; (3) Option 3: In addition, the Pronto-7 rainbow 4D Reusable Sensor and the Pronto-7 Spot Check Pulse CO-Oximeter may be returned for a refund. Customers were also instructed to complete the Tracking/Verification Form provided with the recall notice and fax it to Masimo at: 1-949-297-7499.
