Clinical trials

This prospective, multi-center clinical trial evaluates the safety and efficacy of the Coronary Laser Atherectomy System for the pretreatment of coronary artery stenosis. The study consists of two phases: a first-in-human (FIM) phase enrolling 5 subjects in a single center, and a pivotal phase, which is a prospective, multi-center, randomized controlled, non-inferiority trial enrolling 218 subjects across approximately 10 centers in China. Subjects are randomized 1:1 to receive either the investigational laser system or the control Philips CVX300 laser system for lesion pretreatment prior to PCI. The primary endpoint is clinical success, defined as successful PCI with residual stenosis \<30%, TIMI flow grade 3, and no death, myocardial infarction, or target lesion revascularization through 7 days post-procedure. Secondary endpoints include device success, procedural success, MACE, target lesion failure, and target vessel failure at 30 days and 6 months. An OCT sub-study is planned for 40 subjects.

This study is a prospective, multicenter, randomized controlled clinical trial designed to evaluate the safety and efficacy of the coronary sinus balloon pump (manufactured by Shanghai MicroPort Rotapace Medical Technology Co., Ltd.) as an adjunctive therapy during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). As a pivotal study, it aims to support the product registration application to the National Medical Products Administration (NMPA).

This is a prospective, multicenter clinical investigation aiming to evaluate the safety and efficacy of the coronary sinus balloon pump in its first application in patients with acute ST-segment elevation myocardial infarction (STEMI).
