Foldable Absorbable Breast Support Matrix for Implant Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current support devices used in breast augmentation and reconstruction, such as acellular dermal matrices and surgical mesh, contribute to the risk of infection and other complications like capsular contracture, seroma, hematoma, and malposition of breast implants.
Innovation Solution
A support device formed from a matrix material, configured to provide tissue support during breast surgery, which includes a foldable sheet with templates for shaping into partial or full coverage around the breast prosthesis, and is designed to reduce the risk of infection and complications by stabilizing the implant and promoting tissue integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acellular dermal matrices and surgical mesh are used as support devices, then tissue support and implant stabilization are improved, but the risk of infection and complications increases
Solution Approach 1:
The patent extracts and removes the harmful components from traditional support devices. The support device is designed without permanent synthetic materials that cause infection risk, instead using temporary absorbable materials that eliminate the foreign body that harbors bacteria and causes capsular contracture.
Solution Approach 2:
The support device is designed to be temporarily functional and then discarded by the body through absorption. The matrix material is configured to provide support during healing and then gradually absorb, eliminating the need for permanent foreign materials that cause long-term complications.
2Duration of action of stationary object
If permanent support devices are used, then long-term structural support is improved, but the risk of capsular contracture and biofilm formation increases
Solution Approach 1:
The support device transitions from a permanent static structure to a dynamic temporary structure. The matrix material changes state over time from providing structural support to being gradually absorbed by the body, adapting its function to match the healing process stages.
Solution Approach 2:
The patent employs a disposable temporary support device made from absorbable materials instead of permanent expensive materials. The device performs its support function during the critical healing period and then naturally degrades, eliminating long-term complications associated with permanent implants.
3Reliability
If traditional support devices are used, then implant positioning is improved, but the risk of seroma and hematoma formation increases
Solution Approach 1:
The patent changes the material parameters of the support device from permanent non-absorbable materials to temporary absorbable materials. This parameter change maintains the positioning function during healing while eliminating the foreign body that causes seroma and hematoma formation long-term.

AI summary
Embodiments described herein relate to a support device configured to provide tissue support, during implant-based breast surgery. Embodiments described herein include a matrix sheet disposed in a foldable sheet including one or more templates including at least one of a partial support template and a full support template. The partial support template is configured for use in shaping the matrix sheet into a support device for partial coverage for a breast prosthesis. The full support template is configured for use in shaping the matrix sheet into a support device for full coverage for a breast prosthesis. In some embodiments, the support device is a bioabsorbable mesh substrate, a bioabsorbable polymer coating, and one or more active pharmaceutical agents for delivery at the surgical site. The support device may be provided in various shapes for coverage of the breast prosthesis or provided with templates for various coverage of the breast prosthesis. The support device forms a macroporous scaffold, and the macroporous scaffold may act as a lattice for new tissue ingrowth.
