Problems solved by technology

However, the material of the metal development point is harder and less flexible than the inner tube. When the distal tortuous lesion is encountered, the inner tube is likely to be discounted and the pushing performance will be deteriorated.
In addition, the presence of metal development points increases the passing outer diameter at the balloon, making it impossible for product to pass through stenotic lesions or heavily calcified areas

Embodiment Construction

[0023] The core idea of ​​the present invention is to provide a balloon catheter, the inner tube of the balloon catheter can be developed at the position where the balloon body is fixed, and the position that can be developed will not increase the passing outer diameter of the balloon body, and It will not reduce its own flexibility.

[0024] In order to make the purpose, advantages and characteristics of the present invention clearer, the following in conjunction with the attached Figure 1~4 The balloon catheter proposed by the present invention is further described in detail. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. It should be noted that the "near end" mentioned in this application refers to the end close to the product operator, and the "distal end" refers to the end away from the product operati...

Abstract

The invention provides a saccule catheter comprising a saccule body and an internal pipe fixing the saccule body. The saccule body has a work section; a part of the internal pipe in the saccule body and forming a cavity is provided with a developing section; and the developing section is manufactured by macro-molecular polymer containing a metal developer. Compared with a way of arranging a metal developing mark on the internal pipe, one part of the internal pipe is made of macro-molecular polymer containing the metal developer, so a via-external diameter of the part of the saccule body and forming the cavity can be reduced when a developing function is provided; and the saccule body can smoothly get to a narrow lesion position. Besides, with the developing section on the part of part of the internal pipe in the saccule body and forming the cavity, the internal pipe has great flexibility compared with the whole section developing, so the saccule catheter can be bent and overall saccule catheter pushing performance is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon catheter for dilating blood vessels. Background technique [0002] Balloon dilatation is an important technology in the field of interventional surgery, which has been studied and widely used in the treatment of coronary heart disease, cerebral thrombosis and other diseases. However, with the improvement of living standards and the reduction of exercise, the diseased blood vessels in the human body are becoming thinner and the lesions are becoming more and more complicated. In order to face complex lesions, the balloon catheter and its stent delivery system are correspondingly endowed with many functional requirements. Among them, the visualization of the balloon catheter is an important functional indicator, and the location of the balloon can be precisely positioned through visualization to ensure the accuracy of balloon dilatation. [0003] The current ball...
