Problems solved by technology

However, this method still has certain limitations. Because the vascular ultrasound catheter and the puncture guide wire are separated, it is difficult for the ultrasound catheter and the guide wire to enter the occluded blood vessel at the same time, and the operation is difficult.

Abstract

The invention provides a treatment catheter in the blood vessel. The treatment catheter comprises a catheter body, a guidance guide wire and a puncture guide wire, a guidance guide wire channel, a puncture guide wire channel and an imaging channel are formed in the catheter body, and an imaging unit is arranged on the head of the imaging channel; the puncture guide wire penetrates out of the puncture guide wire channel, and the guidance guide wire penetrates out of the guidance guide wire channel. According to the technical scheme, the imaging channel, the guidance channel and the puncture guide wire channel are integrated through the catheter, and the catheter is simple in structure, small in diameter, easy to operate, high in reliability, and wide in application range of interventional therapy; particularly, the problem is solved that the guide wire in the common surgery has difficulty in successfully penetrating through CTO lesion and then entering the true lumen, by using the catheter, a stent and the like in the lesion blood vessel false lumen are guided into the true lumen, so that the artery is opened again and the blood flow is unblocked, and the surgical success rate is further improved.

Description

technical field [0001] The present invention relates to a device for interventional treatment, in particular to a catheter for intravascular treatment, in particular to a catheter for treating chronic total occlusion (CTO). Background technique [0002] Coronary heart disease is the number one killer that endangers human health, and coronary artery CTO (Chronic Total Occlusion, chronic total occlusion) is the most serious type. CTO mostly refers to lesions with coronary artery occlusion for more than 3 months, with high morbidity and high mortality. The lesions account for about 1 / 3 of all coronary angiography, but less than 8% of them receive percutaneous coronary intervention (PCI). , accounting for about 15% to 30% of all PCI cases. The significance of successful PCI is that it can relieve the symptoms of angina pectoris, improve cardiac function, reduce the need for coronary artery bypass grafting (CABG), and prolong the life of patients. At present, interventional tre...
