A method for constructing high‐frequency pulsed Doppler ultrasonic microprobes is described. Such probes were constructed and implanted on the femoral arteries of 14 rats. All of the probes gave excellent signals during the early postoperative period and all probes were found to be functional when retrieved one month after implantation. We feel that high‐frequency pulsed Doppler microprobes have important advantages for microvascular monitoring.
