Thermal Vascular Modulation for Localized Blood Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate for effectively treating hypertension or hypotension in localized parts of the vascular system, as they often lead to damage to blood vessels and do not address the root cause of blood pressure imbalances in specific regions like the pulmonary or renal arteries.
Innovation Solution
A system utilizing a constriction device with a cooling surface to reduce blood pressure in the pulmonary artery and a heating surface to dilate the renal artery, combined with a control unit and sensors to regulate temperature and mechanical or hydraulic mechanisms for precise blood vessel modulation, along with the option of electrical stimulation to treat aneurysms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to treat hypertension or hypotension in localized vascular regions, then blood pressure imbalances may be addressed, but damage to blood vessels occurs and the root cause is not effectively treated
Solution Approach 1:
The patent applies local thermal treatment to specific regions of blood vessels affected by hypertension or hypotension. The thermal element is positioned at the exact location of the vascular problem, allowing localized vasomodulation without affecting other parts of the vascular system, thereby treating the root cause while avoiding unnecessary damage to healthy vessels.
Solution Approach 2:
The patent changes the physical parameter of temperature to induce vasomodulation. By controlling the thermal element to deliver specific temperature ranges, the system achieves vasoconstriction or vasodilation effects that address blood pressure imbalances without the mechanical trauma associated with conventional surgical interventions.
2Manufacturing precision
If thermal elements are used to treat localized hypertension or hypotension, then precise blood pressure control in affected areas is achieved, but the system complexity increases
Solution Approach 1:
The patent employs a multi-functional device that integrates thermal elements, sensors, and control mechanisms into a single system capable of treating both hypertension and hypotension. The same device can adapt its function based on the detected condition, reducing the need for multiple separate treatments and simplifying the overall therapeutic approach.
Solution Approach 2:
The patent incorporates sensors that continuously monitor blood pressure or flow parameters and feed this information back to the control system. This closed-loop feedback mechanism enables automatic adjustment of thermal element activation, achieving precise blood pressure control while minimizing manual intervention and reducing operational complexity.
3Stress or pressure
If cooling surfaces are used to constrict blood vessels and reduce blood pressure, then localized hypertension is treated, but the risk of tissue damage from extreme temperatures increases
Solution Approach 1:
The patent implements protective measures by designing the cooling surface to operate within safe temperature ranges that prevent tissue damage. The system includes temperature monitoring and control mechanisms that activate before dangerous temperature levels are reached, cushioning against potential harm while still achieving the desired vasoconstriction and blood pressure reduction effects.
