Description

technical field [0001] The invention relates to a balloon size measuring device and method, in particular to a balloon size measuring device and a measuring method of a PTCA (percutaneous transluminal coronary angioplasty) balloon expansion catheter. Background technique [0002] PTCA is the English abbreviation of "Percutaneous Transluminal Coronary Angioplasty". That is to use a long and thin soft catheter, guide wire, balloon and other related equipment to dilate the significantly narrowed or even occluded coronary artery lesion under the guidance of X-ray fluoroscopy and contrast agent, so as to open and dilate the lumen , to improve and restore coronary blood flow. In order to further keep the lumen open and maintain normal blood flow, stent implantation is often performed after PTCA. Balloon size measurement refers to the measurement of the formed size of the balloon after expansion under the nominal use pressure. If the balloon is too long and the expansion is too ...
