Abstract

The invention discloses a miniature inflatable balloon occluder for a coronary artery. Thevminiature inflatable balloon occluder comprises an elastic sheath; an elastic pad is fixedly connected to theinner wall of the elastic sheath; a sealing block is fixedly connected to the left side of an inner chamber of the elastic sheath; a catheter is embedded in the left side of the sealing block; the right side of the catheter penetrates into the right side of the sealing block and extends to the inner chamber of the elastic sheath; the right side of the surface of the catheter is fixedly sleeved with a micro balloon; a suture line is arranged at the top of the micro balloon; and a notch used in cooperation with the suture line is formed in the surface of the elastic sheath. By arranging the elastic sheath, the micro balloon, the suture line, the notch, the catheter, the elastic pad, the sealing block, the myocardium and the coronary artery which are cooperatively used,the miniature inflatable balloon occluder disclosed by the invention has the advantages of repeatability and safety, and solves the problems that an existing balloon occluder is large in balloon diameter, not suitable forsmall animals, used in arteries and not capable of being retained in the bodies of the animals for a long time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a miniature coronary artery inflatable balloon occluder, which is mainly used in the preparation of small animal coronary or main artery ischemia models. Background technique [0002] Medical devices refer to direct or indirect instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items, including the required computer software. Experiments. At present, most of the animal models of ischemic cardiomyopathy are prepared by thoracotomy and ligation of coronary arteries, or using balloon inflation to block the steel wire to directly injure the arterial intima to cause myocardial ischemia. The conventional method of preparing ischemic cardiomyopathy models requires many repetitions. One-time thoracotomy, complex operation, low reproducibility, large infection, long model making cycle, high mortality rate; while ...
