Pre-Shaped Acellular Tissue Matrix for Full Breast Implant Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acellular tissue matrices used in breast surgeries require time-consuming reshaping and resizing, are costly, and lack pre-formed shapes for complete coverage and attachment to anatomical structures, leading to inefficiencies and potential complications.
Innovation Solution
Development of pre-sized and pre-shaped acellular tissue matrix devices with flexible sheets having specific curvatures and attachments for complete coverage and support of breast implants, including features like preformed tabs, slits, and holes for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If surgeons reshape and resize tissue matrices during surgery, then the tissue matrix can be adapted to fit different patient needs, but the operative time increases and material waste increases
Solution Approach 1:
The tissue matrix is pre-shaped and pre-sized to match specific implant configurations before surgery. The patent describes tissue matrices with pre-formed curves, angles, and dimensions that correspond to standard implant shapes, allowing surgeons to implant them directly without time-consuming reshaping operations.
Solution Approach 2:
The tissue matrix is designed as a modular component that can be selectively combined with different implants. The patent describes a system where pre-shaped tissue matrices can be paired with various implant types (round, teardrop, anatomical) to create customized breast profiles, allowing adaptability without requiring intraoperative modification of the matrix itself.
2Adaptability or versatility
If surgeons reshape and resize tissue matrices during surgery, then the tissue matrix can be adapted to fit different patient needs, but the cost increases
Solution Approach 1:
The tissue matrix is pre-shaped and pre-sized to match specific implant configurations before surgery. The patent describes tissue matrices with pre-formed curves, angles, and dimensions that correspond to standard implant shapes, allowing surgeons to implant them directly without time-consuming reshaping operations.
Solution Approach 2:
By providing pre-shaped tissue matrices that fit standard implant configurations, the patent reduces the need to discard portions of expensive acellular dermal matrix material during intraoperative reshaping. The pre-formed shapes minimize trim waste while maintaining the ability to adapt to different patient anatomical requirements.
3Reliability
If tissue matrices are made larger to provide complete coverage, then coverage is improved, but the cost and complexity increase
Solution Approach 1:
The tissue matrix incorporates localized features such as pre-formed curves, angles, and dimensional variations that are specifically positioned to match the anatomical requirements of different implant types. The patent describes how the matrix has varying thicknesses, curvatures, and shapes in different regions to optimize coverage and fit for specific implant configurations without requiring the entire matrix to be oversized.
