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.
Read MoreWe 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.
Read MoreBalloon 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.
