Petal-Shaped Acellular Matrix for Breast Prosthesis Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implantable tissue matrices for breast prosthesis in surgeries such as breast augmentation and reconstruction often require on-site tailoring, leading to inefficiencies, increased surgical time, and suboptimal aesthetic outcomes due to irregular shapes and sizes, as well as complications like ptosis and translocation of the prosthesis.
Innovation Solution
A support device for breast prosthesis based on acellular tissue matrix material, featuring petal-shaped planar biological matrix blanks with connected edges forming bowl-shaped or cup-shaped surfaces, and incorporating drainage holes, manufactured through decellularization and sterilization of human or animal-derived materials, allowing for pre-tailored fitting and integration with the breast tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tissue matrices are tailoring on-site during surgery, then the device can be customized to fit the patient's specific anatomy, but the surgical time increases and the shape may be irregular leading to suboptimal aesthetic outcomes
Solution Approach 1:
The tissue matrix device is pre-shaped into a cup shape before surgery, eliminating the need for on-site tailoring. This preliminary preparation reduces surgical time while maintaining the ability to fit patient anatomy through the pre-designed cup configuration that can accommodate breast prostheses
2Reliability
If autologous tissues are used for breast prosthesis support, then the integration with patient's body is excellent, but the surgery complexity increases and additional donor site wounds are introduced
Solution Approach 1:
The tissue matrix device serves as an intermediary between the breast prosthesis and the patient's body. This intermediate structure provides the necessary support and integration without requiring complex autologous tissue reconstruction, thereby reducing surgical complexity while maintaining reliable integration
3Ease of manufacture
If breast prosthesis is implanted without adequate support structure, then the surgical procedure is simpler, but the prosthesis may prolapse or translocate over time affecting aesthetic effect
Solution Approach 1:
The cup-shaped tissue matrix device acts as a flexible supportive structure that conforms to the breast prosthesis. This thin film-like structure provides adequate support to prevent prolapse and translocation while maintaining surgical simplicity, as the device is pre-formed and requires no complex assembly during surgery

AI summary
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.
