It really depends on the patient. What we've done for these implants--there are six different implants--is we've published what we call a summary basis of decisions. So in that summary basis of decisions, it actually lists all the common adverse events that you see with the products, and it actually gives you, whether it's for a primary surgery or a subsequent surgery, what the percentage risk is for those occurrences. Again, depending on what the adverse event is, they will be different for different devices.
In general, beyond the fact that no medical device is 100% safe, these are not intended to be lifetime devices. We think the average lifetime of a silicone gel-filled implant is between seven and ten years. So they will require replacement, and that's a surgical process.
In terms of other adverse events, it really depends on what the adverse event is and what the reaction is in the person as to whether or not that would require additional surgery or some other form of medical treatment.
