Technical Field
The utility model relates to the technical field of catheter devices, in particular to a high-strength radiography catheter device.
Background
Prosthetic heart valve implantation is currently a common means of treating valvular heart disease. Before performing a prosthetic heart valve implantation procedure, it is often necessary to measure the pressure differential across the valve and to image the aortic valve area to diagnose the valve operation, providing reference data for the procedure. It is also necessary to measure the valve-crossing pressure difference after the prosthetic heart valve implantation procedure and to visualize the aortic valve area to determine the recovery of the patient after the procedure. The transvalve pressure difference refers to the difference of blood pressure on two sides of a heart valve or a blood vessel valve, and is an index commonly used for evaluating valve stenosis in heart color Doppler ultrasound examination. The transvalve differential pressure is typically measured by ultrasonic imaging techniques and calculated. Since the ultrasound imaging measurements are indirect measurements, there is some error in the measured data from the actual data. On the other hand, in imaging the aortic sinus region, it is generally necessary to perform imaging by introducing a separate imaging catheter before or after the operation. In view of the difficulty in ensuring high strength of the catheter and minimizing injury to the human body, there is a need for an improvement in the current catheter devices to solve the above-mentioned problems;
