Inflatable Medical Device Delivery System with Controlled Inflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional delivery systems are inadequate for efficiently and precisely inflating or expanding inflatable medical devices or implants in a non-invasive manner, lacking the necessary precision and minimally invasive capabilities.
Innovation Solution
A surgical inflation and delivery system featuring a container with a hollow shaft and a detachable clip that limits the shaft's movement, combined with protrusions on the inner and outer surfaces to prevent the outlet from releasing prematurely, allowing for controlled inflation and delivery of inflatable content through a lumen or container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional delivery systems are used to inflate medical devices, then the devices can be delivered, but the inflation process is imprecise and invasive
Solution Approach 1:
The inflatable device is nested within a delivery catheter system, allowing the device to be delivered through a minimally invasive catheter and then inflated in situ. The delivery catheter contains the inflated device during delivery, and upon deployment, the device is inflated to its functional size at the target location.
Solution Approach 2:
The system uses fluid (hydraulic or pneumatic pressure) to inflate the medical device after delivery. A balloon or expandable structure is inflated with fluid through the delivery catheter, enabling precise control of the inflation process and device expansion at the target site without requiring open surgical access.
2Ease of operation
If the outlet is made detachable for delivery, then the delivery process is simplified, but the outlet may release prematurely
Solution Approach 1:
The outlet connection transitions from a static fixed state to a dynamic controllable state. The outlet is securely attached during delivery through the catheter, then can be deliberately detached or opened at the target location through a controlled mechanism such as a release trigger, button, or mechanical disengagement feature.
Solution Approach 2:
The outlet is pre-secured to the inflatable device during the delivery process, ensuring it remains attached while navigating through the catheter. The detachment or release mechanism is prepared in advance but only activated at the appropriate time and location, preventing premature release while enabling controlled deployment.
