Re: New Draft FDA Guidance to distinguish b/w Recall and Product Enhancement & Report
If you can put permanent labeling on an instrument itself, it can carry an End of Life Date. Assuming that labeling is sufficiently prominent, I think clinicians can reasonably be expected to understand that use of the instrument beyond that date is not permitted.
If some durable means of clinician-communicated life definition is not used, the Forever problem eventually may become overwhelming if the number of units in service is large.
