Problems solved by technology

However, after medical stainless steel enters the human body, when the passivation layer or protective layer on the surface is damaged due to corrosion or abrasion, its metal ions are easily enriched in the tissues near the intervention, affecting the normal metabolism of the organism.

Embodiment Construction

[0018] Specific embodiments of the present invention are described in detail below in conjunction with accompanying drawing:

[0019] The PEEK balloon dilatation catheter used for endovascular interventional therapy in this embodiment includes a proximal tube 3 , a distal tube 2 and a balloon 1 as shown in the drawings.

[0020] The proximal tube 3 is made of PEEK (polyether ether ketone) resin as a main raw material, and glass fiber or carbon fiber is added as a reinforcing agent.

[0021] The proximal tube 3, the distal tube 2, and the balloon 1 are sequentially seamlessly welded to form a PEEK balloon dilatation catheter

[0022] The invention eliminates harmful metal ions entering the human body from the source to induce toxic effects, cell destruction and inflammatory reactions, improves the safety of human vascular devices, and has the advantages of repeated sterilization at high temperatures, excellent mechanical properties, good lubricity, Dimensional stability and ot...

Abstract

The invention relates to a PEEK balloon dilatation catheter for an intravascular interventional treatment operation, which comprises a balloon, a distal tube and a proximal tube, wherein PEEK (Polyetheretherketone) resin is adopted as the main raw material of the proximal tube, so that the PEEK balloon dilatation catheter not only has good high-temperature resistance, mechanical property, lubricating property and dimensional stability, but also prevents harmful metal ions from entering a human body to induce a toxic effect and generate cell damage and inflammation reactions from a source.

Description

technical field [0001] The invention relates to a medical instrument for intravascular intervention, in particular to a PEEK balloon expansion catheter. Background technique [0002] In the interventional operation for the treatment of vascular blockage, the balloon dilation catheter is sent to the lesion, and the dilation balloon is used to dilate the blood vessels in the lesion stenosis, expand the lumen, increase the blood flow, and improve the blood supply. [0003] The catheter part of the balloon dilatation catheter is made of different materials and seamlessly welded to form a proximal tube and a distal tube. The proximal tube is generally made of medical stainless steel. Medical stainless steel has good corrosion resistance and comprehensive mechanical properties, and is the most widely used and widely used material in biomedical metal materials. However, after medical stainless steel enters the human body, when the passivation layer or protective layer on the surfa...
