Solution Overview
Problem
Existing treatments for aortic aneurysms, such as stent implantation, are prone to complications like embolism and lack robustness in preventing aneurysm bursting.
Innovation Solution
A device comprising an implantable member that applies pressure on the aneurysm, adjustable postoperatively, with optional electrical stimulation to increase aneurysm wall tonus, and a control system for pressure regulation based on sensor feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stent implantation is used to treat aortic aneurysm, then the aneurysm can be reinforced and bursting prevented, but embolism complications occur and the procedure lacks robustness
Solution Approach 1:
The patent introduces a balloon catheter as an intermediary device that temporarily blocks the aneurysm sac during the procedure. This mediator prevents direct contact between foreign materials and the aneurysm wall, reducing embolism risk while enabling effective reinforcement through the balloon's blocking action
Solution Approach 2:
The patent replaces traditional mechanical stent implantation with a balloon-based system that uses inflatable pressure to block and reinforce the aneurysm. This substitution eliminates the need for permanent foreign material insertion, reducing embolism complications while maintaining reinforcement effectiveness
2Reliability
If surgical intervention is performed to treat aortic aneurysm, then the aneurysm can be addressed, but open surgery is required which increases procedural complexity and risk
Solution Approach 1:
The patent replaces open surgical intervention with a minimally invasive balloon-based system. The balloon catheter can be introduced through smaller incisions and guided to the aneurysm location, eliminating the need for large open surgeries while maintaining effective aneurysm treatment
Solution Approach 2:
The balloon catheter serves as a minimally invasive intermediary that can be introduced through peripheral vessels and guided to the aneurysm site. This mediator enables effective treatment without requiring direct surgical access to the aneurysm, reducing procedural complexity and surgical risk
3Reliability
If a device is designed to apply pressure to the aneurysm, then the aneurysm expansion can be prevented, but the device requires control systems and sensors increasing complexity
Solution Approach 1:
The patent implements a self-regulating balloon system that automatically adjusts pressure based on aneurysm response. The balloon incorporates sensors and control mechanisms that detect aneurysm expansion and autonomously modify the applied pressure, eliminating the need for complex external control systems while maintaining effective containment
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
Prevents aneurysm expansion and bursting by applying controlled pressure, reducing the risk of complications and allowing for non-invasive adjustment and monitoring.
Implementation Method 1
The member is adapted to be placed in connection with a blood vessel having the aneurysm and to exercise a pressure on the aneurysm
Implementation Method 2
an electrical pulse generator adapted to provide electrical signals for stimulation of the aneurysm wall via electrodes located on the inside of the implantable member

AI summary
A device for treating an aneurysm of a human or mammal patient, wherein the aneurysm may self-expand. The device comprising an implantable member adapted to be placed in around an outside of a blood vessel having the aneurysm to enable the implantable member to exercise a pressure on the outside of the blood vessel having the aneurysm. The device further comprising a measuring device or sensor for measuring or sensing an expansion of the aneurysm and a monitoring system adapted to monitor the expansion of the aneurysm based on a signal received from the measuring device or sensor.
