Title
(EN) MEDICAL DEVICES TO LIMIT MOVEMENT OF BREAST IMPLANTS
(FR) DISPOSITIFS MÉDICAUX POUR LIMITER LE MOUVEMENT D'IMPLANTS MAMMAIRES
Abstract
(EN)
Breast fixation devices for use in breast reconstruction and breast augmentation limit the rotation or movement of breast implants after implantation that results in an unnatural appearance of the breast. The breast fixation devices can include a thin-walled enclosure in the shape of a pouch. A breast implant is secured inside the pouch to limit movement by applying compression to the breast implants, or using a mating or interlocking mechanism between the pouch and breast implant. The pouches containing the breast implants are implanted in the breast. Tissue in-growth into the pouch limits movement of the pouch-breast implant assembly and thereby limits rotation, migration, and displacement of the breast implant. The pouches preferably comprise poly-4-hydroxybutyrate or copolymer thereof.
(FR)
Selon l'invention, des dispositifs de fixation de sein destinés à être utilisés dans la reconstruction mammaire et l'augmentation mammaire limitent la rotation ou le mouvement des implants mammaires après implantation qui conduit à une apparence non naturelle du sein. Les dispositifs de fixation de sein peuvent comprendre une enceinte à paroi mince sous la forme d'une poche. Un implant mammaire est fixé à l'intérieur de la poche pour limiter le mouvement par application d'une compression sur les implants mammaires, ou à l'aide d'un mécanisme d'accouplement ou de verrouillage entre la poche et l'implant mammaire. Les poches contenant les implants mammaires sont implantées dans le sein. La croissance tissulaire dans la poche limite le mouvement de l'ensemble poche-implant mammaire et limite ainsi la rotation, la migration et le déplacement de l'implant mammaire. La poche comprend de préférence du poly-4-hydroxybutyrate ou son copolymère.
