Document Type and Number:
WIPO Patent Application WO/2023/191250
Kind Code:
A1
Abstract:
The present invention relates to a vascular clip for blood flow control, wherein the vascular clip is based on a shape-memory polymer and serves to partially occlude a vessel through which excessive blood flow passes due to the incomplete automatic regulatory function thereof so as to induce normal blood flow and release the occlusion when the automatic regulatory function recovers, the occlusion is released, whereby when applied as a device to substitute for the lost automatic regulatory function of the vessel, the vascular clip can prevent cerebral hyperperfusion syndrome in advance, thus solving problems caused by the syndrome and can eliminate the risks of removal surgery, thus providing safety and convenience for patients.
