Evaluate the Safety and Efficacy of Intracoronary Lithotripsy Balloon Catheter and Intracoronary Lithotripsy Apparatus

Coronary Artery Disease Clinical Trial

Official title:
Evaluate the Safety and Efficacy of Intracoronary Lithotripsy Balloon Catheter and Intracoronary Lithotripsy Apparatus for Preconditioning of Coronary Calcified Lesions in a Prospective, Multi-center, Single-group Clinical Trial

Clinical Trial Summary

This is a prospective, multi-center, single-group target value clinical trial, which will be carried out in many clinical trial institutions in China. A total of 184 subjects (70 of them are OCT subgroups) are planned to be enrolled, all subjects were treated surgically with intracoronary lithotripsy using a balloon dilatation catheter and intracoronary lithotripsy apparatus after a single-group registration, clinical follow-up was carried out within 7 days after operation or before discharge, 1 month and 6 months after operation. The success rate of operation was taken as the main end point to verify the effectiveness of balloon dilatation catheter and intracoronary lithotripsy apparatus.

Clinical Trial Description

This is a prospective, multi-center, single-group target value clinical trial to recruit patients with coronary artery calcification, coronary artery calcification was pretreated with balloon dilatation catheter and intracoronary lithotripsy apparatus made by Shanghai Blusail Boyuan Medical Technology Co. , Ltd. , to verify the safety and efficacy of balloon dilatation catheter and intracoronary lithotripsy instrument for intravascular preconditioning of coronary artery calcification lesions. This trial will be carried out in many clinical trial institutions in China, and a total of 184 subjects (70 of them are OCT subgroups) are planned to be enrolled, all subjects were treated surgically with intracoronary lithotripsy using a balloon dilatation catheter and intracoronary lithotripsy apparatus after a single-group registration, clinical follow-up was carried out within 7 days after operation or before discharge, 1 month and 6 months after operation. In this study, the success rate of operation was taken as the main end point to verify the effectiveness of balloon dilatation catheter and intracoronary lithotripsy apparatus. A clinical summary report was issued for registration of the product 1 month after completion of postoperative follow-up, based on which a 6-month postoperative follow-up was performed to assess its safety. The secondary end points were angiographic success, device success, target lesion failure at 1 and 6 months, severe angiographic complications, MACE events at 1 and 6 months, serious adverse events and adverse events, and device defects. In the OCT Subgroup, the secondary end points were the minimum stent area (MSA), the minimum stent lumen diameter (MLD), the lumen acquired diameter, the lumen acquired area, and the lumen acquired rate of the immediate postoperative, the expansion rate of the stent, and the incomplete adherence rate of the stent beam. ;
