A Clinical Trial Evaluating the Pan-vascular Interventional Robotic System for Panvascularization Interventional Surgery

Inclusion criteria

• General Inclusion criteria:

• 18 years old ≤ age ≤85 years old;
• have a clinical indication for PCI (clinical evidence of ischemic heart disease or a positive functional study);
• Subject or guardian can understand the purpose of the experiment and sign informed consent voluntarily Book and willing to cooperate to complete the follow-up.

• Angiographic inclusion criteria:

• The stenosis degree of visual target lesion ≥50%;
• 2.5mm≤ Visual target vessel diameter ≤4.0mm;
• Visual target lesions ≤38mm in length, or successive small lesions that can be completely covered by a single stent;
• Target lesions to be treated intraoperatively cannot be treated in stages.

Exclusion criteria

• General exclusion criteria 1)A stroke occurred within 30 days prior to surgery; 2)Percutaneous coronary intervention was performed within 72 hours before surgery; 3)Acute myocardial infarction, cardiogenic shock, or infarction occurred within 48 hours before surgery Received CPR; 4)Other cardiac procedures (such as aortic valve placement) are scheduled within 30 days of surgery Coronary artery bypass grafting, etc.); 5)Pregnant or lactating female subjects; 6)Severe hepatic or renal insufficiency or bleeding tendency; 7)Known allergy to interventional device materials and their coatings, or allergy to contrast agents; 8)Severe stenosis, occlusion of blood vessels at the intended puncture site, or local skin infection and uncontrollable; 9)Are participating in other interventional clinical studies, and have not completed the evaluation of the primary endpoint of the relevant study; 10)Participants who had other contraindications for interventional therapy or were judged by the investigator to be unsuitable for participation in the study;
• Angiographic exclusion criteria 1)The TIMI blood flow grade of the target lesion was < 2; 2)Treatment requiring intrastent restenosis, or prior placement of a stent in the target vessel near both ends of the target lesion; 3)Severe tortuosity or severe calcification of blood vessels; 4)There's an intracavitary thrombus; 5)In addition to balloon forming and stent implantation, other treatments (such as atheromatectomy, rotary grinding, laser ablation, etc.) are also required at the same time; 6)The researchers determined that percutaneous coronary intervention was not suitable for robotic assistance or that there might be high risks in the process.
