The invention relates to a
catheter for
endovascular treatment on hypertension, in particular to a medical
catheter for clinical endovascular
intervention treatment on hypertension. The
catheter has the functions of monitoring the temperature of the
vascular tissue of the
renal artery and measuring the local impedance of the tissue of the
renal artery, and is used for carrying out
feedback regulation on radio and
high frequency current intensity to block bilateral renal sympathetic nerves and interdict sympathetic nerves to excite the
kidney to generate and secrete renin-angiotensin, thereby achieving the purpose of reducing
blood pressure. The catheter provided by the invention is made by
compositing temperature plastic polymers and wire meshes, wherein the
hardness of a near end is larger, a far end is softer, and multiple channels are formed in a catheter body; a far-end
electrode is made from
platinum (or gold) composite materials at the front end of the catheter, and multiple leads and drawing wires of the
electrode are connected with a
handle and a joint through the channels in the catheter body; and high-efficiency
electrical isolation pipes and drawing pipes arranged in the channels of the catheter body ensure electrical
signal transmission and smooth traction, thereby finishing bending and stretching operations.
