METHOD FOR OBTAINING OF IMPLANTS OR INTERMEDIATE PRODUCTS OF SUCH IMPLANTS, AND IMPLANTS AND INTERMEDIATE PRODUCTS OBTAINED USING THIS METHOD Russian patent published in 2017 - IPC A61F2/12 

FIELD: medicine.

SUBSTANCE: methodis implemented for production of implants or intermediate products of such implants, in particular breast implants, which comprises: a) provision of an implant shell with a front side, a back side and an area connecting the said front and back sides and comprising unvulcanized silicone made of and containing several layers of unvulcanized silicone. Moreover, the implant shell does not terminate as it represents an intermediate product still containing unvulcanized reaction zones on the outer surface of the implant shell, and the implant shell is obtained by provision of a casting mould into which layers of unvulcanized silicone are applied stage-by-stage. At that, the unvulcanized silicone is substantially liquid or dissolved in a solvent. b) positioning of the first sheet of foam comprising or made from one layer of polyurethane to a portion of the front side, the area connecting the front and back sides and a back side portion of the unvulcanized implant shell as provided in step a). c) the step of vulcanization of the implant shell obtained in step b) to vulcanize the silicone from step a), thereby binding the first foamed plastic sheet to the implant shell. d) removal, in particular, trimming of an excess sheet of expanded plastic not bonded by vulcanization in step c) to the back side of the implant shell. e) application of a sheet containing partially or completely uncured silicone onto the back side of the implant shell, thereby in particular covering these parts not covered with the first foam sheet.

EFFECT: strengthening of the implant layers connection and excluded delamination.
