Abstract
A catheter and guide wire assembly for measurement of blood pressure in a living body, including a tubular shaft, which is connected to a tubular extension, which is connected to a permeable helical coil, which has a distal end that is secured in a distal tip, and a core member, which is attached in a distal portion of the tubular shaft and extends through the tubular extension and the helical coil, and is secured in the distal tip. The catheter and guide wire assembly has an outer diameter of about 0.35 mm and an open, inner lumen, which includes the tubular shaft, the tubular extension, the helical coil, and the core member. The catheter and guide wire assembly has a total flow-resistance index less than about 1.2×10mm, and more preferably less than about 1.0×10mm, and even more preferably less than about 0.7×10mm.
