Patient's question:
Married for 1 year without pregnancy, want a babyDoctor's answer:
The American COOK guidewire system used in clinical practice consists of 2 delicate catheters and 1 platinum guidewire. One catheter is approximately 30 cm long with an outer diameter of 1.0 mm and a lumen diameter of 0.7 mm. The front end of this catheter, about 3 cm long, forms a blunt angle curve with the catheter, with an angle of approximately 140 degrees. The distal end of the catheter is slightly conical and blunt, designed to press against the openings of the uterine and fallopian tubes. The platinum guidewire has a diameter of approximately 0.4 mm. The primary function of the guidewire is to facilitate insertion into the fallopian tubes to serve as a guide, while the catheter can also be used for fluid infusion.
