Sealed Working Chamber for Isolated In-Body Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical procedures face challenges in creating a working space within the body that is free from interference by extraneous anatomical structures or substances, particularly in areas where continuous functioning or normal materials may interact and hinder the procedure, such as in endoscopic gastrointestinal procedures where inadequate bowel preparation leads to incomplete or rescheduled procedures.
Innovation Solution
A chamber device with proximal and distal sealing members is used to create a working space within the body, isolating the target area from surrounding anatomy and substances, allowing for procedures to be performed without extensive cleaning of the entire bowel by sealing the chamber with flexible elongate elements that conform to the anatomical structure and allow access through defined openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the entire bowel is thoroughly cleaned through dietary restrictions and medication, then the working space is free from interference by fecal materials, but the procedure time and resource consumption increase significantly
Solution Approach 1:
The bowel is segmented into a treated working space and an untreated surrounding space using the chamber device. The chamber isolates only the specific target area requiring intervention, allowing fecal clearance to be limited to this small segment rather than the entire bowel, thereby reducing preparation time and resource consumption while eliminating harmful interference in the working area.
Solution Approach 2:
Instead of uniformly cleaning the entire bowel, the invention applies cleaning only locally to the specific target area within the chamber. The chamber device creates a localized working space where fecal materials are removed, while the rest of the bowel maintains its normal state, optimizing the balance between clearance effectiveness and procedure efficiency.
2Object-affected harmful factors
If the entire bowel is thoroughly cleaned through dietary restrictions and medication, then the working space is free from interference by fecal materials, but the complexity of preparation procedures increases
Solution Approach 1:
The preparation procedure is simplified by segmenting the bowel into a treated working space and untreated portion. The chamber device enables focused cleaning of only the necessary target area, eliminating the need for complex systemic bowel preparation protocols and reducing the overall complexity of the preparation process.
Solution Approach 2:
The chamber device acts as an intermediary that creates a isolated working space, allowing the procedure to be performed in a controlled environment without requiring extensive pre-procedure bowel preparation. This intermediary structure simplifies the preparation requirements by providing a physical barrier that confines the working area.
3Object-affected harmful factors
If the chamber device seals the working space from surrounding anatomy, then interference from extraneous materials is eliminated, but the device complexity increases
Solution Approach 1:
The chamber device utilizes flexible sealing members that can conform to the anatomical structures, creating an effective seal without requiring complex rigid mechanisms. The flexible nature of the sealing members allows them to adapt to the bowel's shape and movement, providing reliable isolation from extraneous materials while maintaining device simplicity.
Solution Approach 2:
The sealing members are designed to be dynamic and adaptable, capable of adjusting to the anatomical structures they contact. This dynamic design allows the chamber to maintain an effective seal against extraneous materials while accommodating natural anatomical movements, reducing the need for complex fixed sealing mechanisms.

AI summary
Devices, systems, and methods configured to form a chamber along or adjacent a target area within a patient at or along which a procedure is to be performed. The chamber is sealed with respect to the target area to form a sealed enclosed working area sealed from external anatomical structures, materials, substances, processes, etc. The target area is thus isolated so that a procedure may be limited to the working area without influence or interference of surrounding anatomical structures, materials, substances, processes etc.
