PTCA balloon dilatation catheter is a percutaneous balloon dilatation catheter for the treatment of coronary artery stenosis and blockage. It consists of a tip, balloon, marker, hub, etc, and is usually inserted into the body through a vessel puncture point for treatment.During surgery, the doctor i
The Octoparms® Vena Cava Filter, initiated for development in 2014, entered the National Medical Products Administration's "Green Channel" for innovative medical devices in May 2020, and received approval for market launch in August 2021, filling the market gap for domestically produced umbrella-typ
Introduction:The Peripheral Vascular High-Pressure Balloon Dilatation Catheter represents a cutting-edge solution in the field of peripheral vascular interventions. Specifically designed to address peripheral vascular diseases and conditions, this innovative catheter offers enhanced capabilities for
The vena cava filter is a medical filter. It can be used for percutaneous placement in inferior vena cava of people with high risk of pulmonary embolism, and can prevent pulmonary embolism. The appearance of vena cava filter is a milestone in the history of venous thrombosis treatment.
We all know that catheter-based surgical procedures need to guide the catheter to the target area for treatment or to obtain tissue samples for diagnosis. However, due to the anatomical structure and the interaction between human soft tissues and the catheter, the operator usually needs to push and retreat the catheter repeatedly to change the direction. At this time, if the catheter is manipulated to bend, the movement track of the catheter can be limited to make it reach the target position as soon as possible and correctly.
Balloon dilatation catheter is a flexible catheter with an inflatable balloon at its head, which is used to expand narrow hollow organs in human body, such as blood vessels, digestive tract, urinary tract, etc. under the guidance of images. Under the condition of no inflation, the balloon catheter enters the target lesion, and after successful treatment, the balloon can be retracted to withdraw the balloon catheter to the outside of the body. Several basic characteristics of vascular dilation balloon are as follows: balloon compliance and dilation force. From the strictest point of view, compliance refers to the change value of volume every time a unit pressure is changed. For most PTA balloon catheters, increasing the pressure length does not change. Therefore, the change of volume is mainly reflected in the change of balloon diameter.
As a minimally invasive technique, vena cava filter implantation index has become one of the preferred treatment methods for VTE patients. Nowadays, interventional radiology has become the third largest clinical diagnosis and treatment means after medical treatment and surgical treatment, and is widely used in clinic. Pulmonary embolism is the most serious complication of deep venous thrombosis of lower limbs, and inferior vena cava filter is one of the most effective prevention methods. What is the vena cava filter for? Generally speaking, vena cava filter is an instrument used to prevent pulmonary embolism caused by deep venous thrombosis of lower limbs falling off and returning to the heart. This article will introduce the history of inferior vena cava filter.
The main purpose of PTCA balloon dilatation catheter is to dilate patients' narrow coronary artery diseased vessels and improve myocardial blood flow through minimally invasive interventional surgery. It can also be used to deliver the release stent to the coronary artery stenosis of patients.
