Abstract

The invention discloses an HVPG balloon catheter and a manufacturing method thereof. The HVPG balloon catheter comprises a first tubular body and a second tubular body; the first tubular body is a double-cavity tube, and the proximal end of the first tubular body is provided with a first connecting member; the second tubular body is a single-cavity tube, the proximal end of the second tubular body is provided with a second connecting member, and the distal end of the second tubular body is connected and communicated with the side wall of the proximal end of the first tubular body through a three-way member; a balloon sleeves the side wall of the distal end of the first tubular body, and the balloon is communicated with first tubular body; the first tubular body is provided with development marks respectively at positions of the two ends of the balloon; a plurality of side holes are formed in the head end of the first tubular body in the radial direction. By using the HVPG balloon catheter, more accurate monitoring results can be obtained, a doctor can better position the HVPG balloon catheter under X-ray, and the HVPG balloon catheter can better reach the lesion through tortuous blood vessels.

Description

technical field [0001] The invention relates to a HVPG balloon catheter used in interventional operations, which is used for monitoring the hepatic venous pressure gradient (HVPG), and is mainly used to solve the problem of difficult positioning of the balloon catheter, poor monitoring accuracy and poor passing performance when monitoring the hepatic venous pressure gradient. Good question, which can better meet the needs of clinical use. Background technique [0002] Portal hypertension is an important factor affecting the clinical prognosis of patients with liver cirrhosis, and its severity determines the occurrence and development of complications of liver cirrhosis (such as rupture and bleeding of esophageal and gastric varices, ascites, hepatorenal syndrome, etc.). According to reports, the number of patients with liver disease in my country has exceeded 400 million, which is the country with the heaviest burden of liver disease in the world. Among them, there are about...
