Embodiment Construction

[0032] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the drawn drawings are only used to illustrate preferred embodiments of the present invention, and should not limit the protection scope of the present invention. The protection scope of the present invention should be limited only by the claims.

[0033] see Figure 1-3 , the transthoracic minimally invasive mitral valve balloon dilatation catheter of the present invention comprises a balloon 2, an inner catheter 3, an outer catheter 5, a four-way seat 7, an exhaust connecting tube 9, an inner catheter connector 10, a sealing ring 14 and Parts such as sealing cap 11. The balloon 2 has a three-layer structure, the inner and outer capsules are all medical latex materials, and the middle is a nylon mesh. The inner catheter 3 is a single-lumen catheter made of polypropylene material, and the outer catheter 5 is a single-lumen c...

Abstract

The invention provides a transthoracic minimally invasive balloon mitral valvuloplasty catheter. The transthoracic minimally invasive balloon mitral valvuloplasty catheter comprises a balloon (2), an inner catheter (3), an outer catheter (5), a four-way seat (7), an air exhaust connection pipe (9), an inner catheter connector (10) and a sealing body, and the four-way seat (7) is provided with an air exhaust port (8), a sealing port and a filling port (12). The transthoracic minimally invasive balloon mitral valvuloplasty catheter is smaller in size, wider in adaptive surface, smaller in operative wound, and easier and more accurate to operate.

Description

technical field [0001] The invention relates to a balloon dilation catheter of a medical device, in particular to a transthoracic minimally invasive mitral valve balloon dilation catheter. Background technique [0002] Rheumatic heart disease is a common disease in developing countries, and there are about 3 million patients with rheumatic heart disease in my country. Surgery is the main method for the treatment of rheumatic heart valve disease, including closed dissection, direct vision angioplasty and biological valve or artificial valve replacement, and the treatment effect is constantly improving. In 1984, Inoue and in 1985, Lock developed the percutaneous balloon mitral valvuloplasty (PBMV) successively, which gradually replaced closed dissection. After years of clinical verification, the effect is reliable and the patient suffers less pain. Complications are low and it has been accepted by cardiac surgeons. [0003] Although percutaneous balloon mitral valve dilatati...
