Embolectomy and thrombolysis device for visceral arterial embolism

Abstract

An embolectomy and thrombolysis device for visceral arterial embolism comprises a plurality of independent flexible-shaft-shaped balloon blocking catheters, a first guide wire with the diameter of 0.018 inches, a flexible-shaft-shaped balloon embolectomy catheter, a second guide wire with the diameter of 0.035 inches, and a flexible-shaft-shaped thrombolysis catheter with a drug injection cavity. The external diameter of each of the flexible-shaft-shaped balloon blocking catheters is 3F, each flexible-shaft-shaped balloon blocking catheter comprises a guide channel, a water injection channel and an expanding blocking balloon, wherein the guide channels penetrate through the catheters axially, and the expanding blocking balloons located at the distal ends of the catheters are communicated with the water injection channels. The external diameter of the flexible-shaft-shaped balloon embolectomy catheter is 4F or 5F, the flexible-shaft-shaped balloon embolectomy catheter comprises a guide channel and a water injection channel, wherein the guide channel penetrates through the flexible-shaft-shaped balloon embolectomy catheter axially, and an expanding embolectomy balloon located at the distal end of the flexible-shaft-shaped balloon embolectomy catheter is communicated with the water injection channel. The drug injection cavity penetrates through the flexible-shaft-shaped thrombolysis catheter axially. Through the cooperation of the balloon blocking catheters, the first guide wire, the balloon embolectomy catheter, the second guide wire and the thrombolysis catheter, the embolectomy and thrombolysis device can simplify operations, reduce injuries to patients due to the operations, lower the risk of the operations and increase the survival rate of the patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a thrombus removal and thrombolysis device for visceral artery embolism. Background technique [0002] With the gradual improvement of the level of medical diagnosis, more and more cases of acute embolism of visceral arteries are diagnosed early clinically. Acute embolism of visceral arteries mainly refers to acute embolism of celiac artery, superior mesenteric artery, and renal artery. Among them, the celiac artery originates from the abdominal aorta at almost right angles, so acute embolism rarely occurs, and even if acute embolism occurs in the celiac artery, because there are abundant anastomotic branches between the celiac artery and other visceral arteries, it is easy to establish collateral circulation. Therefore, severe clinical symptoms rarely occur; as for the superior mesenteric artery and bilateral renal arteries, since both the superior mesenteric artery and bilateral ...

AI Technical Summary

Problems solved by technology

At present, the clinical treatment of acute embolism of this type of artery is very difficult, mainly relying on laparotomy or retroperitoneal major surgery to remove the thrombus under direct vision. Many, heavy, so that the operation rate of the patient is low, and the damage to the patient is greater; at the same time, because one of the most important causes of acute arterial embolism is cardiogenic disease, most patients cannot bear the blow of this type of operation, resulting in The mortality rate of patients is very high, and the operation risk is high
