the present invention relates to a support device for breast prosthesis based on an acellular matrix material of a biological tissue . the support device for breast prosthesis is formed by tailoring a membranaceous material into a petal - shaped planar biological matrix blank and by connecting adjacent edges thereof . the support device can match with the breast prosthesis ; and provide a support , fixation and coverage for the breast prosthesis in various surgical operations such as mammoplasty and breast orthopedics , to avoid the ptosis and translocation of the breast prosthesis , thereby achieving desirable effects of plastic surgery . once being implanted , the matrix material of a biological tissue can be integrated into the surrounding breast tissue of the subject , and thus transformed into new tissues in human body without the retention of foreign bodies . the present invention further relates to a method for manufacturing a support device , and a membranaceous biological matrix material .
