Interventional Brain Electrode Implant via Vascular Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for implanting electrodes into the brain, especially deep in the brain, often result in nerve cell damage due to the invasive nature of traditional surgical procedures.
Innovation Solution
An interventional device is developed to implant electrodes into the brain via a blood vessel, utilizing a first guide member, a second guide member, and a puncture kit to establish support points in the vascular channel and puncture the blood vessel wall in a target area, allowing for precise electrode implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional surgical methods (bone removal and window opening) are used to implant electrodes into the brain, then electrodes can be implanted into the brain including deep brain areas, but nerve cell damage in non-target areas and brain damage may occur
Solution Approach 1:
The patent uses a blood vessel as an intermediary pathway to reach the brain. Instead of directly accessing the brain through bone removal, the electrode is delivered through the vascular system (carotid artery → intracranial artery → target brain area), which serves as a natural corridor that avoids damage to cortical nerve cells while enabling deep brain access.
Solution Approach 2:
The patent divides the electrode implantation process into multiple segments: (1) accessing the blood vessel through a puncture in the neck area, (2) navigating through the vascular tree using guide members, (3) delivering the electrode through the vessel lumen, and (4) positioning the electrode at the target site. This segmentation allows each step to be performed with minimal trauma.
2Adaptability or versatility
If traditional surgical methods are used to implant electrodes, then electrodes can be placed in the brain, but the surgical procedure is complex and traumatic
Solution Approach 1:
The patent employs a multi-functional interventional device system that combines: (1) a puncture needle for vascular access, (2) guide members for navigation and support, (3) an electrode delivery catheter, and (4) positioning mechanisms. This universal system can access various brain regions through a single vascular entry point, simplifying the overall surgical approach compared to multiple separate procedures.
3Ease of operation
If bone removal and window opening are performed, then direct access to the brain is achieved, but significant trauma is caused to the patient
Solution Approach 1:
The blood vessel serves as a natural intermediary that provides a pre-formed pathway to the brain. By utilizing the existing vascular anatomy (carotid artery and its branches), the procedure avoids the need to create new access paths through bone and tissue removal, thereby eliminating the associated trauma while maintaining ease of access to deep brain structures.

AI summary
The present disclosure relates to an interventional device for implanting an electrode into the brain via a blood vessel, the blood vessel having a blood vessel channel and a blood vessel wall, characterized in that the interventional device comprises: a first guide member, the distal end of which can move distally in the blood vessel channel and establish a first support point in the blood vessel channel; a second guide member, the distal end of which can pass through the first guide member to move distally in the blood vessel channel and establish a second support point in the blood vessel channel, so that the second guide member extends in an arc shape between the first support point and the second support point; and a puncture kit, the puncture kit being used to carry the electrode, and the distal end of the puncture kit being able to pass through the first guide member to move distally in the blood vessel channel and puncture the blood vessel wall in a target puncture area between the first support point and the second support point, thereby implanting the carried electrode into the brain. Furthermore, the present disclosure relates to a medical apparatus.
