Abstract

The invention relates to a transradial renal artery ablation guide catheter. The transradial renal artery ablation guide catheter includes a handle, a main catheter section and a control bending catheter. The main catheter section is communicated with the far end of the handle. The control bending catheter is communicated with the far end of the main catheter section. Woven reinforcement threads are arranged in the catheter wall of the main catheter section. Pulling thread cavities are correspondingly formed in the catheter wall of the main catheter section and the catheter wall of the controlbending catheter. An adjusting disc is arranged in the handle. A control rod is connected to the adjusting disc. Pulling threads sliding backwards and forwards are arranged in the pulling thread cavities. The far ends of the pulling threads are fixed to the catheter wall of the control bending catheter, and the near ends of the pulling threads are fixed to the adjusting disc. The control rod controls the adjusting disc to rotationally adjust the pulling threads to extend or contract in order to control the bending shape of the control bending catheter. According to the transradial renal artery ablation guide catheter, the head end of the catheter can control the bending shape, a radiography passage of the renal artery is the radial artery, a traditional arteria femoralis path is avoided,and complications of artery arteriopuncture can be reduced.

Description

technical field [0001] The invention belongs to the technical field of renal artery ablation, in particular to a renal artery ablation guiding catheter through radial artery. Background technique [0002] The existing renal artery angiography and ablation path is mostly the femoral artery, and there is no dedicated renal artery ablation catheter with the radial artery as the path, and femoral artery puncture is prone to complications. The bending of the front end of the existing renal arteriography and ablation catheter is not easy to control, and it is not convenient to operate the opening of the renal artery, which is easy to cause damage and increases the risk of the operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a catheter for renal artery ablation through the radial artery, which facilitates the bending control of the front end of the catheter and reduces the complications of femoral artery punct...
