Problems solved by technology

The shape of the existing balloon after filling is generally cylindrical. Due to the extrusion of the balloon by the stenotic part of the blood vessel, it may cause the balloon to slide to the distal or proximal end during the filling process, that is, it cannot be guaranteed that the final expansion part is The exact position of the stenotic part of the blood vessel affects the expansion effect

Abstract

The invention discloses a balloon catheter. The balloon catheter comprises a balloon capable of dilating and deforming and a conveying tube used for conveying the balloon to a hemadostenosis part and communicated with an inner cavity of the balloon, wherein a groove used for being matched with the hemadostenosis part after the balloon is full is formed in the middle of the balloon. The hemadostenosis part is located in the groove, two ends of the balloon are well attached to blood vessel lumens at two ends of the hemadostenosis part, the stability of the balloon can be improved, axial limitation is increased, axial displacement is avoided, and positioning accuracy is realized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon catheter. Background technique [0002] Vascular stenosis is an important cause of ischemic diseases. Due to the reduction of blood supply, tissue ischemia and cell death result. At present, the commonly used treatment methods include drug treatment, surgical treatment and interventional therapy. Among them, endovascular interventional therapy is the most widely used, and interventional therapy can be used to treat vascular stenosis through balloon expansion. Balloon dilation is to extend the balloon at the end of the balloon catheter delivery tube into the stenotic part of the blood vessel, and expand the stenotic part of the blood vessel by inflating the balloon to improve the blood supply to the distal end. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of the position of the balloon filling state in the blood vessel in the prior art. The s...
