Balloon Sheath With Integrated Suction Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures lack an effective method to apply suction within body passageways, particularly in procedures requiring obstruction removal or bleeding control, where existing technologies do not adequately address the need for controlled fluid and suction management.
Innovation Solution
A balloon sheath system with a suction member and manifold configuration that allows for controlled inflation and deflation of a balloon member, enabling fluid and suction management through dedicated passages, facilitating obstruction removal and bleeding control by inflating to stop blood flow and applying suction to extract obstructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a balloon catheter is used to occlude blood flow, then bleeding control is achieved, but the ability to apply suction within the body passageway is lost
Solution Approach 1:
The device is divided into functionally distinct segments: a balloon portion for occlusion and a suction member with suction port for fluid removal. This segmentation allows each component to perform its specialized function independently while working together as an integrated system.
Solution Approach 2:
The patent combines the balloon catheter and suction member into a single integrated device. The suction member extends forward from the balloon portion, merging two previously separate functions (occlusion and suction) into one unified tool that can perform both bleeding control and fluid evacuation simultaneously.
2Productivity
If suction is applied through the balloon catheter, then fluid removal is achieved, but control over fluid and suction management becomes inadequate
Solution Approach 1:
The device incorporates dedicated passages that are functionally segmented: a first passage for fluid communication with the balloon and a second passage for suction communication with the suction member. This segmentation provides independent control pathways for fluid management and suction application.
Solution Approach 2:
The manifold serves as an intermediary component that coordinates between the fluid delivery system and suction system. It provides a centralized control point that manages both fluid injection into the balloon and suction application through the suction member, improving operational control.
3Device complexity
If a single catheter design is used, then device simplicity is maintained, but the ability to perform both occlusion and suction functions is compromised
Solution Approach 1:
The catheter is designed as a universal device that performs multiple functions: the balloon portion provides occlusion capability while the suction member provides fluid removal capability. This multi-functional design allows a single device to replace what would traditionally require separate instruments.
Solution Approach 2:
The suction member is nested within or integrated with the balloon catheter structure. The suction member extends forward from the balloon portion, creating a compact nested configuration that maintains relative simplicity while enabling dual functionality.
