Breast Implant I.D. List of the "Official" Unique Product Identifiers for Dow Corning Implants reprinted from Appendix A of the Dow Corning Revised Settlement Documents
D. Unique Product Identifiers. The following unique product identifiers of a Dow Corning Breast Implant(s) shall be considered as acceptable proof where the removed implants are examined by a physician who identifies the manufacturer or brand. See paragraph 7 of Section B
B.7 Medical records of the explanting physician (or other physician or appropriate professional who examined the Claimant's implant during or after removal surgery) - written at the time of the examination of the Breast Implant - if that physician or other appropriate professional points out a specific characteristic of the Breast Implant that is on the list of characteristics unique to Dow Corning implants as specified at Section D. below.
1. For implantations or implants manufactured between 1969 and 1973 a high profile contour "ski slope" design implant with Dacron fixation patches on the posterior with the upper portion of the implant being concave and the bottom portion convex. If the fixation patch has detached from the implnat, then the Claims Office shall accept and shall deem as acceptable proof a photograph of the implant showing an impring consisting of 3-4 linear impressions of the Dacron mesh embedded in the elastomer shell.
2. An implant with fixation patches where white Dacron knit mesh loops were either sewn or bonded to the elastomer patch surface with the fixation patches in turn bonded to the envelope posterior. Products with the following configurations of fixation patches are acceptable:
(i) For implants implanted or manufactured between 1963 and 1965, a single large Dacron mesh-reinforced fixation patch covering all or almost all of the posterior implant surface of a silicone gel-filled implant with a prominent non-everted peripheral seam where the fixation patch is constructed of Dacron mesh-reinforced silicone elastomer sheeting to which non-embedded Dacron mesh had been sewn with Dacron sutures. (1963-1965)
(ii) For implants implanted or manufactured between 1963 and 1969, four (4) Dacron mesh-reinforced fixation patches, one in each quadrant on the posterior implant shell, asymmetric or symmetric, with a distinct peripheral seam everted or non-everted, where the fixation patches are constructed of Dacron mesh-reinforced silicone elastomer sheeting to which non-embedded Dacron mesh has been sewn with Dacron sutures.
(iii) For implants implanted or manufactured between 1968 and 1982, two (2) to five (5) circular Dacron mesh fixation patches on the posterior implant shell of the embedded/pleated design, consisting of a clear elastomer disc about 22-25 mm diameter, with a pattern of embedded Dacron mesh in a pleated pattern, with the actual Dacron mesh present or absent.
(iv) For implants implanted or manufactured between 1968 and 1976, a dumbbell-shaped Dacron mesh-reinforced fixation patch on the posterior implant shell, together with one, three, or four additional round fixation patches on the implant shell. Internal to the dumbbell-shaped fixation patch are either two round shell holes (one larger than the other) separated by a slit in the shell, or a single round shell hole.
3. For implants implanted or manufactured between 1971 and 1975, an eccentrically placed racetrack (oval) shaped posterior shell patch, Dacron mesh-reinforced, outside the implant shell. Internal to the patch are either two round shell holes (one larger than the other) separated by a slit in the shell, or a single round shell hole.
4. A leaflet valve consisting of a proximal round part, attached to which is a distally rounded leaflet valve. The junction of the proximal and distal parts of the valve is also rounded (flared). (This identifier applies to Saline implants implanted or manufactured between 1979-1984; and to gel/saline implanted between 1981-1992.)
5. An implant having one of the following as an imprinted logo on the posterior (for double-lumen implants such markings are only present on the inner lumen patch):
(i) DOW CORNING (1978-1992)
(ii) SILASTIC II (1981-1992)
(iii) DOW CORNING WRIGHT (1989-1992)
6. An implant with both (a) Mandrel Code and (b) Designation Number imprinted together on the posterior centered or near the patch of the implant envelope. These shell markings consist of a single letter or one or two numerals approximately 4mm height with a close-by series of three or four approximately 2mm height numerals. For double-lumen implants such markings will be on both shells. The following Mandrel Codes and Designation Numbers are acceptable:
(i) Mandrel Codes (numbers 1-16, 20,30,40,50,60 or single uppercase letters A-R) (1969 to 1992) and
(ii) Mandrel Designation Numbers (three, or rarely four digit numbers where the characters are between 1/16 inch and 5/64 inch (1.5 mm to 2.0 mm ) in height (1974 to 1992)
7. An implant with a 1.7 inch-long orientation bar (a linear raised strip of elastomer permanently bonded to the posterior of the shell of contour shaped implants) aligned with the long axis of the implant (1975 to 1986).
8. An implant (SILASTIC MSI) with a surface covered by tiny micro pillars (1989 to 1992)
