MDL-926 (RSP) Unique Identifiers
(Bristol / Baxter / 3M / McGhan Breast Implants)

Below is a list of unique identifiers that may be helpful in identifying your implants as a Bristol or Baxter product.  You may find, in your quest to determine your implant manufacturer, that these are helpful.  Occasionally, plastic surgeons make mention of these identifiers in operative reports.  They are also sometimes found in pathology reports.  We know of a specialist who uses these, and may other unique identifiers, along with years of experience to determine the maker of your implants.  Click here to learn how to have your implants professionally identified yourself.
