Problems solved by technology
[0002] At present, percutaneous renal artery sympathetic nerve ablation is mainly performed through the femoral artery, and the main disadvantages are as follows: a. The structure of the catheter tip is fixed, and it cannot effectively cope with the anatomical structure of different renal artery openings during the operation, which increases the surgical cost. operation time and complexity, and reduce the safety of the operation; b. A single femoral artery approach increases the risk of peripheral arterial complications. Puncture in the femoral artery has the possibility of retroperitoneal hemorrhage and lower extremity arteriovenous fistula. After the sheath, the compression is more difficult and the process is cumbersome

The invention relates to a renal artery ablation radiography / guide catheter with a controllable bend head end. The renal artery ablation radiography / guide catheter comprises a handle (1), a pull rod (2), a catheter (3) and the controllable bend head end (4), wherein the handle (1) is of a hollow tubular shape; one end of the handle (1) is a connector and is connected with a contrast medium storage instrument; the other end of the handle (1) is connected with the catheter (3); the catheter (3) is a double-cavity pipe; one cavity of the double-cavity pipe is a contrast medium delivery pipe (5) which is communicated with the contrast medium storage instrument; the other cavity of the double-cavity pipe is a control pipeline (6). The renal artery ablation radiography / guide catheter with the controllable bend head end has the advantages that the head end of the catheter is of a controllable bend structure, different renal artery dissection structures are adapted to, the coaxial property of the catheter and the renal artery is increased, the time of operation is shortened, and the operation safety is improved.
Description
technical field [0001] The invention belongs to the technical field of renal artery angiography / guide catheter, in particular to a renal artery ablation angiography / guidance catheter with controllable bending at the head end.
