Problems solved by technology

Moreover, when the guide wire retrograde technique needs to be applied, the outer diameter of the outer tube is relatively large, which is easy to limit the selection of small-diameter blood vessels such as the septal branch that the balloon catheter passes through, which affects the implementation of the surgical method.

Embodiment Construction

[0055] In the following, the present invention will be described in detail and specifically through specific examples, so as to better understand the present invention, but the following examples do not limit the scope of the present invention.

[0056] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0057] see figure 1 , the present invention provides a balloon catheter 10 . Usually, the end of the balloon catheter close to the operator is the proximal end, and the end away from the operator is the distal end. The balloon catheter includes a needle hub 11 , a heat shrinkable tube 12 and a hypotube 13 arrange...

Abstract

The invention discloses a balloon catheter, which comprises: a hypo tube with an expansion cavity; an inner tube with an expansion cavity, and an outer tube with an outer diameter, wherein the inner tube is located in the outer tube and is coaxial on the longitudinal axis Arranged in a shape, the distal end of the hypotube is located between the proximal end of the outer tube and the proximal end of the inner tube; a balloon with only a cone, wherein the proximal end of the balloon is connected to the distal end of the outer tube, and the distal end of the inner tube Located in the balloon and connected with the distal end of the balloon; and several guide wires located between the inner tube and the outer tube, the proximal end of each guide wire is fixed to the distal end of the hypotube. The balloon catheter of the present invention can ensure the pushability and bending resistance of the above-mentioned distal guide wire, that is, ensure the flexibility of the distal guide wire, and at the same time, enable the balloon catheter to pass through the small lesion smoothly, and improve the performance of the above-mentioned balloon catheter. Catheter penetration.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a balloon catheter. Background technique [0002] In the balloon catheter, the guide wire in the balloon catheter is mainly used to increase the pushability and bending resistance performance, and the comprehensive index of these two performances can be expressed by deflection. [0003] The pushing force of the guide wire is the ability of the guide wire to pass through the lesion under the action of the operator manipulating the push rod outside the body. In the case of guidewires of the same material, pushability depends on the bending stiffness of the guidewire. The bending stiffness of the guide wire is related to the diameter of the guide wire, the thicker the guide wire, the better the pushability. However, the larger the diameter of the guide wire, the larger the inner diameter of the outer tube of the balloon catheter, so the outer diameter of the outer tube is also lar...
