During surgery, a catheter is often inserted into the patient as an aid for guiding. What characteristics should medical guiding catheters boast for use effectiveness?
1. Good physical performance
Guiding catheter is an essential tool in the medical field and should be of good physical properties, such as durability, bending resistance, sliding, propulsion, and trackability. Only with these properties, the catheter is less likely to break, wear or lead to other types of accidents.
2. Chemical stability and x-ray contrast
Medical guiding catheters are inevitably affected by different environments after they are manufactured. In order to ensure the use of catheters, catheters should be made from materials with better chemical stability and drug resistance, sterilization resistance, etc. In addition, the catheter should be of good x-ray contrast for better observation during use.
3. Biological adaptability and blood compatibility
Catheters should be of good biological adaptability since many of them are intended to be implanted in human body. And only with better aging resistance, decomposition resistance, no adsorption and no sediment generation, with good anti-coagulant and anti-thrombotic properties, catheters will not cause adverse effects on human body.
In summary, guiding catheters should meet the above-mentioned characteristics in order to function better and meet the needs of clinical medicine. Therefore, this catheter has high requirements for material and use effect, and thus catheters are of important significance in medical development.
