Intracranial Atherosclerotic Stenosis
Conditions
Keywords
Intracranial balloon, stenosis
Brief summary
This test took the target lesion restenosis rate 6 months after the operation as the main endpoint to verify the effectiveness of the intracranial balloon expansion catheter of Biolimus coating. After completing the follow-up 6 months after the operation, a clinical summary report was issued for the registration application of the product, and on this basis, 12 months of postoperative follow-up was carried out to evaluate the mid-term curative effect.
Interventions
Through the expansion after the balloon is in place,Release drugs on the surface of the balloon and improve the blood perfusion of nerve vessels to treat stenosis
Through the expansion after the balloon is in place, improve the blood perfusion of nerve vessels to treat stenosis.
