Embodiment Construction

[0056] Below in conjunction with accompanying drawing, the present invention will be further described by specific embodiment:

[0057] See figure 1 , an embodiment of a balloon catheter system, including a balloon assembly that strengthens the cutting effect, and a catheter 4 and a buffer tube 5. The balloon assembly includes a balloon 1 and a metal mesh 2 wrapped outside the balloon 1, and the metal mesh 2 includes a connecting proximal end 21, a connecting distal end 22 and an action section 23 connected between the two. The connecting proximal end 21 and the connecting distal end 22 are both zigzag-shaped circumferential windings, and the circumferential windings The apex at the crest or trough is the connection point with the action section 23, and several auxiliary cutting elements 3 are arranged on the action section 23; the catheter 4 passes through the buffer tube 5 and is connected with the proximal end of the balloon 1, and the proximal end of the buffer tube 5 Con...

Abstract

Disclosed is a balloon catheter system. The balloon catheter system comprises a catheter, a buffer tube and a balloon assembly for enhancing the cutting effect, wherein the balloon assembly comprisesa balloon and a metal net wrapping the balloon; the metal net comprises a connecting near end, a connecting far end and an action section connected between the connecting near end and the connecting far end, wherein the connecting far end is connected with the far end of the balloon; a plurality of auxiliary cutting elements are dispersedly arranged on the action section; the catheter penetrates through the buffer tube and is connected with the near end of the balloon; and the near end of the buffer tube is connected outside the catheter, and the far end of the buffer tube is connected with the near end of the catheter. The device is accurate in positioning in the blood vessel, can provide expansion force far larger than that of a traditional structure, can effectively expand a highly calcified lesion part, improves the medicine utilization rate, reduces blood vessel damage, reduces the restenosis rate, and is worthy of application and popularization in the field.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon assembly and a balloon catheter system with enhanced cutting effect. Background technique [0002] The invasive use of percutaneous transluminal angioplasty represents a major advance in the treatment of vascular disease. After more than 20 years of development, balloon angioplasty has become a relatively mature technology recognized by the medical community. Balloon angioplasty is mainly aimed at the revascularization of narrowed and occluded blood vessels. By inserting a catheter with a dilated balloon into the vascular system, the balloon expands in the narrowed and occluded area of ​​the blood vessel under the pressure released from the outside, so as to Radial pressure is applied to the inner wall of the blood vessel, widening the narrowed, occluded area and allowing better blood flow. [0003] Traditional balloon angioplasty mainly introduces a balloon i...
