Pressure monitoring guidewire.

摘要

Pressure monitoring guidewire (10) and method of using the same for a coronary procedure such as angioplasty, angiography, or valvuloplasty. The guidewire (10) has a hollow tubular member (13) with a pressure monitoring port (31) toward the distal end thereof. The distal end portion of the guidewire (10) is advanced beyond the distal end of the dilatation catheter, with the pressure monitoring port (31) in a portion of the coronary anatomy where pressure is to be monitored. With the guidewire (10) so positioned, the pressure in the desired portion of the coronary anatomy is measured at the proximal end of the guidewire through the luminal opening (14) in the hollow tubular member (13).
