Abstract
A medical probe such as a catheter comprises a flexible, elongated member having distal and proximal ends, with Doppler-type velocity measuring means carried within said probe adjacent said distal end, and electrical wires carried within the probe and communicating between the measuring means and the proximal probe end for connection to an electronic system for processing signals from the Doppler chip. By this invention, at least a portion of the probe, including the distal end and Doppler crystal has an ovoid cross-sectional shape. The portion has a maximum cross-sectional dimension and a minimum cross-sectional dimension substantially perpendicular thereto to provide lateral spaces for flow outside of the probe while the probe resides in a blood vessel.
