Abstract

The invention discloses an intervention catheter which comprises a catheter body (1), wherein a side hole (3) communicated with a catheter cavity of the catheter body (1) is formed in a catheter wall (2) of the catheter body (1); the intervention catheter also comprises a strengthened layer (4) arranged on the catheter wall (2); the distribution area of the strengthened layer (4) corresponds to that of the side hole (3). After the intervention catheter provided by the technical scheme of the invention is adopted, the problems that in the background art, the intervention catheter provided with the side hole is easy to break and insufficient in strength at the part of the side hole can be solved.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and more specifically to an interventional catheter. Background technique [0002] In recent years, with the advancement of imaging equipment, the introduction and improvement of new interventional devices have enabled the rapid development of intravascular interventional diagnosis and treatment as a minimally invasive treatment. Intravascular interventional diagnosis and treatment allow doctors to deal with more and more complex lesions, more and more cases are used in clinical practice, and the types of diseases involved are more and more extensive. [0003] At present, interventional catheters with side holes are used for a large part of the disease types, such as when operating catheters in blood vessels or delivering guide wires, balloons, stents or occluders for interventional therapy, when the catheter is placed in the stenosis of the blood vessel Sometimes it will cause blood vessel blo...
