Problems solved by technology

Due to the long distal section of the catheter, this type of angiography catheter needs to be rotated into a loop in the aortic arch and super-select blood vessels on the arch.
In addition, this type of contrast catheter is easy to be discounted during the loop forming and untwisting process, which increases the risk of surgery

Abstract

The invention discloses a trans-right radial artery III type aortic arch cerebral angiography catheter. The catheter comprises an inner tube and an outer tube, wherein the inner tube comprises a firsttube section, a second tube section, a third tube section and a fourth tube section; an included angle of 135-145 degrees is formed between the first tube section and the second tube section, and a first bend bent towards the outer side is formed; an included angle of 40-55 degrees is formed between the second tube section and the third tube section, and a second bend bent towards the inner sideis formed; an included angle of 130-140 degrees is formed between the third tube section and the fourth tube section, and a third bend bent towards the outer side is formed; the outer tube is coaxially arranged on the outer side of the inner tube in a sleeving mode; and the hardness of the outer tube is smaller than that of the inner tube, so that the outer tube can move along the inner tube. According to the angiography catheter, a loop does not need to be formed in the aortic arch, blood vessels on the arch can be directly super-selected, and the loop forming step of a Simmons catheter is omitted.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a type III aortic arch total cerebral angiography catheter through the right radial artery. Background technique [0002] Total cerebral angiography via the right radial artery is currently an important method explored by many cerebrovascular intervention centers. Compared with the conventional transfemoral artery approach, the complications at the puncture point are significantly reduced. The position of the radial artery is superficial and the inner diameter is small. It is easy to pinpoint the arterial breach and stop bleeding. Puncture site bleeding complications requiring surgical intervention were as low as 0.06%. After interventional treatment via radial artery approach, the patient has a higher degree of comfort, no strict bed rest is required, the hospital stay is significantly shortened, and the hospitalization cost is low. [0003] However, most of the angiography cath...
