Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices for approximating and aligning tissue planes are cumbersome and costly, requiring complex parts and connectors, and often lead to increased wound tension and scarring due to inadequate force control.
Innovation Solution
A medical device with a pre-defined shape that can be deformed to load potential forces, applying directed force vectors across a tissue plane by reverting to its original state upon attachment, providing controlled approximation, alignment, distraction, or compression without complex parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex parts and connectors are used to approximate and align tissue planes, then the device can provide structural support and alignment, but the device becomes cumbersome and costly
Solution Approach 1:
The patent combines multiple functions (alignment, approximation, and force application) into a single integrated bridge structure. The bridge comprises a first portion, a second portion, and a connecting portion that work together as one unified component to approximate and align tissue planes without requiring separate connectors or multiple parts.
Solution Approach 2:
The bridge structure serves multiple functions simultaneously: it provides structural support, aligns tissue planes, applies controlled force through its curved configuration, and maintains tissue approximation. This multi-functional design eliminates the need for separate alignment devices, connectors, and force application mechanisms.
2Reliability
If traditional fixation devices are used to hold tissue planes, then alignment can be achieved, but wound tension increases leading to scarring
Solution Approach 1:
The bridge incorporates a curved connecting portion that distributes mechanical force across a broader area of the wound rather than concentrating tension at single attachment points. This curved geometry allows the bridge to flex and adapt to tissue movement while maintaining approximation, thereby reducing localized tension that causes scarring.
Solution Approach 2:
The bridge is designed with specific geometric parameters (curvature radius, portion lengths, connection angles) that are optimized to provide adequate fixation stability while minimizing tensile force on the wound edges. By carefully controlling these dimensional parameters, the device achieves reliable tissue approximation without excessive tension.
3Manufacturing precision
If rigid structures are used for tissue approximation, then alignment precision can be maintained, but flexibility and adaptability to tissue movement are reduced
Solution Approach 1:
The bridge is designed as a dynamic structure where the connecting portion can flex and deform in response to tissue movement while maintaining the overall alignment function. The curved geometry and material selection allow the bridge to adapt to physiological movements without losing its alignment capability or requiring rigid fixation.

AI summary
Medical devices disclosed herein include pre-defined structures for dispensing forces onto a tissue plane in a living organism and are utilized to adjust spatial relationships, orientations, and mechanical forces in a patient treatment area. The treatment area may be a wound, an incision, or a surgically accessed area within a patient that includes oppositely disposed sections that heal more efficiently and with less scarring when force vectors of a particular magnitude and direction are applied to the treatment area. The medical device provides a structure that may be pre-stressed through planned deformation that develops desirable spatial and mechanical relationships along the tissue plane for alignment, compression, advancement, eversion, inversion, distraction, rotation, angulation, and the control or modulation of tension across the treatment area.
