Abstract
A catheter having a mechanism for positioning a doppler shift transducer carried by the catheter against a side wall of a blood vessel. A portion of the catheter near the distal end is adjustable for movement between a first position in line with the axis of the catheter and a second position in which such catheter portion is in the shape of an arc extending outward from the axis of the catheter such that the arcuate portion will wedge the body of the catheter against the other wall of the blood vessel. The adjustable portion can be manipulated using a mechanism near the proximal end of the catheter outside of a patient's body.
