AI Technical Summary
In percutaneous perfusion arterial intervention, the friction between the guidewire and the interventional device is relatively large, which can lead to guidewire displacement, increasing the complexity and time of the procedure, especially in narrow blood vessels where anchoring balloon catheters cannot be used for positioning.
A medical catheter is designed that combines the functions of a guiding catheter and an anchoring balloon. The guidewire is positioned by the balloon in the infusion channel, avoiding the need for additional anchoring devices. The guidewire is positioned by the balloon pressing against it when inflated.
No additional anchoring devices are needed, reducing surgical complexity, shortening surgical time, avoiding difficulties in guidewire positioning due to vascular stenosis, and improving surgical efficiency.
