Aorto-Mitral Prosthesis Shaping for Low-Tension Valve Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical procedures for replacing the cardiac aorto-mitral curtain during valve replacements in the human heart often result in insufficient attention to the right and left fibrous trigons, leading to increased tension on sutures, potential disruption, and complications such as bleeding and aneurysms, while current solutions increase operation complexity and duration.
Innovation Solution
A pericardial patch designed as a cardiac aorto-mitral prosthesis that anatomically replaces the cardiac aorto-mitral curtain, including the left and right fibrous trigons, with a shaping that matches the natural anatomy, and can be implanted through various surgical approaches, reducing tension and complications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single pericardial patch is used to reconstruct the intervalvular fibrous body, then the surgical procedure is simplified, but the anatomical accuracy is insufficient and suture tension increases
Solution Approach 1:
The prosthesis is divided into multiple leaflets (first leaflet, second leaflet, third leaflet, fourth leaflet) that correspond to different anatomical regions of the intervalvular fibrous body. Each leaflet can be independently sized and shaped to match specific anatomical features, including the left and right fibrous trigons, thereby achieving accurate anatomical reconstruction while maintaining surgical simplicity.
2Loss of time
If the intervalvular fibrous body is inadequately reconstructed, then surgery time is reduced, but suture tension increases leading to complications
Solution Approach 1:
The prosthesis is pre-formed with the correct anatomical shape including all necessary contours for the left and right fibrous trigons before the surgical procedure. This preliminary preparation eliminates the need for complex intraoperative shaping and suturing, reducing surgery time while ensuring proper anatomical fit that distributes suture tension evenly, thereby preventing suture disruption and bleeding complications.
3Device complexity
If the fibrous trigons are not adequately replaced, then the surgical procedure is simplified, but postoperative cardiac function is compromised
Solution Approach 1:
The prosthesis incorporates specific structural features for the left and right fibrous trigons with distinct shapes and orientations that match the local anatomical requirements. The first leaflet addresses the left fibrous trigon while the second leaflet addresses the right fibrous trigon, ensuring that each critical region receives appropriate anatomical reconstruction tailored to its specific functional requirements, thereby optimizing postoperative cardiac function.

AI summary
The invention is directed to a cardiac aorto-mitral prosthesis for the human heart that replaces the cardiac aorto-mitral curtain during surgical operations to the human heart. The prosthesis is capable to anatomically replace the cardiac aorto-mitral curtain which may be affected during a replacement of the mitral valve or of the aortic valve. The cardiac aorto-mitral prosthesis offers a shaping that matches the anatomic shape of the intervalvular fibrous body including the left and right fibrous trigons between the mitral valve and the aortic valve. The cardiac aorto-mitral prosthesis can be implanted quickly during a surgical operation, thereby shortening the operation time and simplifying the surgical procedure. The cardiac aorto-mitral improves the recovery perspectives and the physical wellness of the patient after the surgical operation. The invention is also directed to a process for the production of the cardiac aorto-mitral prosthesis.
