Dual Channel Probe for Cerebral Spinal Fluid Volume Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for hydrocephalus, such as shunting, are not permanent solutions and do not effectively manage fluid volume within the brain, leading to issues with intracranial pressure, cerebral blood flow, and brain equilibrium.
Innovation Solution
A dual channel probe system that includes a drain element and a volume changing element, allowing for the controlled removal or addition of fluid within the brain, either as an open or closed system, to manage fluid volume and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If shunting is used to remove excess CSF, then fluid accumulation is reduced, but the solution is not permanent and does not effectively manage fluid volume
Solution Approach 1:
The shunt system is transformed from a static passive drainage device to a dynamic active control system. The pump device actively pumps CSF between the ventricle and the distal site, allowing dynamic adjustment of fluid volume based on physiological needs. The controller receives signals from sensors and adjusts pumping activity in real-time, enabling the system to adapt to changing intracranial pressure conditions and provide reliable long-term fluid volume management.
2Quantity of substance
If shunting alone is used, then fluid removal is achieved, but intracranial pressure and cerebral blood flow are not effectively managed
Solution Approach 1:
The pump device integrates multiple functions into a single system: it removes excess CSF, regulates intracranial pressure, and influences cerebral blood flow. The controller coordinates the pump's operation with physiological parameters detected by sensors, allowing the system to perform fluid removal, pressure management, and flow optimization simultaneously. This multi-functional approach replaces the need for separate shunting and pressure management interventions.
Solution Approach 2:
The system incorporates sensors that detect physiological parameters such as intracranial pressure and flow conditions. These sensors provide feedback signals to the controller, which adjusts the pump's operation in real-time. This closed-loop feedback mechanism enables the system to adaptively manage fluid volume, pressure, and blood flow, ensuring optimal physiological conditions are maintained throughout treatment.

AI summary
The present disclosure relates generally to controlling a volume of fluid within a portion of a patient's body. For example, the present disclosure can relate to the addition or removal of cerebral spinal fluid (CSF) from a portion of the patient's brain. The amount of fluid can be controlled by a system that includes a dual chamber probe and a volume control. One channel can include a drain element to drain the fluid from the portion of a patient's body. The other channel can include a volume changing element to facilitate the drainage of the fluid by changing a volume of the portion of the patient's body. The volume changing element can be coupled to a volume control, which can control the change of the volume of the portion of the patient's body (e.g., based on passive oscillation or active oscillation).
