Graft Prosthesis Pocket for Removable Microsystem
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoluminal prostheses lack the capability to collect and monitor physiological data in real-time, limiting their effectiveness in managing vascular conditions such as atherosclerosis, aneurysms, and arterial dissections.
Innovation Solution
Integration of a microsystem within a pocket configuration on the medical device, allowing for the collection of physiological data and enabling the device to be remotely accessed for data retrieval and potential system updates, utilizing a tubular graft material with a magnetically coupled microsystem for secure and removable data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a microsystem is integrated into the endoluminal prosthesis for data collection and monitoring, then the capability to monitor physiological status is improved, but the device complexity increases
Solution Approach 1:
The prosthesis is divided into functional segments: the tubular graft material for structural support and the integrated microsystem for data collection. The pocket structure further segments the device by providing a dedicated compartment that can be accessed independently, allowing the microsystem to be removed or replaced without affecting the main prosthesis structure.
Solution Approach 2:
The microsystem is nested within the pocket of the prosthesis structure. The pocket cavity provides an enclosed space that houses the microsystem components, allowing the monitoring function to be integrated within the existing prosthesis framework rather than adding external complexity.
2Ease of repair
If the microsystem is made removable for in vivo removal and replacement, then the ease of repair and maintenance is improved, but the reliability of the connection may worsen
Solution Approach 1:
The traditional mechanical connection methods (screws, clips, or permanent adhesives) are replaced with magnetic coupling. The magnet embedded in the pocket provides a non-mechanical, yet reliable, attachment mechanism that allows the microsystem to be securely held during normal operation but easily removed when needed by applying external magnetic force or physical manipulation.
3Adaptability or versatility
If a pocket structure is added to house the microsystem, then the adaptability of the device is improved, but the device complexity increases
Solution Approach 1:
Rather than making the entire prosthesis complex and adaptable, the pocket structure is added only in the specific location where microsystem integration is needed. The pocket provides localized adaptability - a dedicated compartment with opening and closing capability - while the rest of the tubular graft material maintains its simple, proven structural design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous monitoring of patient physiological status and device performance, facilitating timely interventions and reducing the need for repeated surgeries by allowing in vivo removal and replacement of the microsystem.
Implementation Method 1
A portion of the graft material may include a magnet to removably couple to a microsystem when received within the enclosed cavity

AI summary
A medical device, such as a prosthesis, may include a graft material and a pocket disposed along at least one of luminal and abluminal surfaces of the graft material. The pocket may include a pocket opening leading into an enclosed cavity. The enclosed cavity may be sized to receive at least a portion of a microsystem, and the pocket may be accessible in vivo for removal of the microsystem from the pocket.
