A guide catheter includes a tubular body having a proximal end and a distal end. A pressure or other sensor is disposed at or near the distal end of the body, preferably having an active surface thereof disposed away from the direction of blood flow when the catheter is present in a particular blood vessel, such as the aorta adjacent to a coronary ostium.

In a guide catheter having a distal end suitable for insertion into a vessel in the vasculature of a patient and a proximal end which remains outside the patient, wherein the distal end has a predetermined shape accessing a coronary ostium, the catheter having an outer wall and a lumen defined there

In a guide catheter having a distal end suitable for insertion into a vessel in the vasculature of a patient and a proximal end which remains outside the patient, wherein the distal end has a predetermined shape accessing a coronary ostium, the catheter having an outer wall and a lumen defined therein, said lumen being adapted for insertion of an interactive catheter and having an open distal end, the improvement comprising at least one pressure sensing element provided in the outer wall of the guide catheter, wherein an active surface of the sensing element faces away from the direction flow of blood when the catheter is positioned adjacent the coronary ostium.
