Clinical Trial Summary

The purpose of this study is to evaluate the safety and effectiveness of spinous process balloon dilation catheter (Plastic-Blade) in coronary vascular diseases, which is not inferior to the similar product on the market - coronary spinous process balloon dilation catheter (lacrosse NSE) produced by Goodman Co., Ltd..

Description:

This study is a prospective, multicenter, randomized, controlled and non inferiority designed clinical trial. A total of 160 subjects with CAD from 8 centers will be randomized 1:1 to each group. All subjects evaluated the immediate lumen acquisition immediately after operation and the MACE of 30 ± 7 days after operation. The primary endpoint is the acquisition of lumen immediately after operation. The effectiveness of balloon was evaluated. The safety of balloon was evaluated by adverse events during operation.Clinical follow-up will be conducted at operation, discharge and 30 ± 7 days after operation. The target lesions included the following : opening lesions, bifurcation lesions, calcification lesions and fibrosis lesions; Diameter stenosis ≥ 70% (visual) with evidence of ischemia; Localized lesions with TIMI ≥ 1; RVD=2.00 and 4.00mm , and the vascular segment is suitable for balloon dilatation in anatomical structure。

Secondary	Incidence of related complications	Including acute occlusion, vasospasm, vascular rupture, branch or collateral occlusion, subacute stent thrombosis, intimal tear, dissection, etc.	30 days after balloon dilatation
Secondary	% change of clinically meaningful laboratory tests	Record the change of clinically meaningful laboratory tests	30 days after procedure
Secondary	Number of adverse events	Adverse events occurred during balloon dilatation, after balloon dilatation to 30 ± 7 days after discharge	30 days
Secondary	Number of device related composite endpoint	Including TLF, Cardiac Death, TV-MI and ID-TLR	30 days
Secondary	Number of patient oriented composite endpoint	Including all cause death, MI, TLR, TVR, Revascularization of any coronary arteries and thrombus at the lesion.	30 days
Secondary	Total time of device operation performance	Push capacity, passing capacity and withdrawal capacity	30 days
