Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balloon angioplasty inflation devices require a stopcock for fluid communication, which creates logistical difficulties and allows for user errors, especially when inflating two balloons simultaneously for the kissing balloon technique.
Innovation Solution
A balloon angioplasty inflation device with a barrel-shaped syringe body, a plunger, and a coupling member, featuring a port controller that allows selective fluid flow to one or both balloon ports, eliminating the need for a stopcock and enabling simultaneous inflation of two balloons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stopcock is used to control fluid communication between the inflation device and balloon, then the device can remove air and control inflation, but the device complexity increases and user error potential increases
Solution Approach 1:
The patent removes the stopcock component entirely from the inflation system. Instead of using a stopcock to control fluid communication, the invention uses a direct valve mechanism integrated into the syringe body that eliminates the need for separate stopcock control, thereby reducing device complexity while maintaining inflation control reliability
Solution Approach 2:
The patent combines the stopcock functionality directly into the syringe valve mechanism. The valve is integrated into the syringe body structure itself, merging what were previously separate components (syringe and stopcock) into a unified system, reducing the number of parts and potential failure points
2Adaptability or versatility
If two separate inflation devices are used for kissing balloon technique, then both balloons can be inflated simultaneously, but the logistical difficulty and user error increase
Solution Approach 1:
The patent creates a single inflation device with multiple ports that can inflate one or two balloons simultaneously. The syringe body includes a first port and second port that both communicate with the same fluid chamber, allowing the device to function as either a single-balloon or dual-balloon inflator, eliminating the need for two separate devices and the coordination complexity they create
Solution Approach 2:
The patent segments the fluid delivery system into separate ports while maintaining a unified fluid chamber. Each port can be independently connected to different balloons, but both receive fluid from the same pressurizable chamber, allowing simultaneous inflation through a single coordinated action
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
The device simplifies the inflation process, reduces user error, and allows for efficient simultaneous inflation of two balloons, improving the reliability and precision of balloon angioplasty procedures.
Implementation Method 1
drawing the plunger from the closed second end to the first open end to create a negative pressure throughout the balloon angioplasty system from the inflation device to the angioplasty balloon to withdraw any air present in the angioplasty balloon
Implementation Method 2
depressing the plunger from the first open end toward the second closed end to drive the contrast-saline solution from the fluid chamber to the angioplasty balloon

AI summary
A balloon angioplasty inflation device and method of inflating a balloon includes a syringe body having a fluid chamber, a plunger slidably disposed within the fluid chamber, and a coupling member coupling the plunger to the syringe body. The plunger includes a plunger valve and a seal including a pressure valve allowing air through the seal. The plunger valve is rotatable between an open position and a closed position to selectively allow air to escape the fluid chamber. The method includes connecting the inflation device to a balloon, drawing the plunger to create a negative pressure to withdraw air from the balloon to the fluid chamber, rotating the plunger valve to the open position to evacuate the air from the fluid chamber, rotating the plunger valve to the closed position to seal the fluid chamber, and inflating the balloon to a desired pressure with a contrast-saline solution.
