Abstract
Systems and methods for navigating a catheter and delivering a needle to a desired anatomic location are provided. The system includes an injection catheter that includes a needle slidably exposed from, or retracted into, the catheter lumen. The system further includes a first acoustic marker located at a distal end of the catheter and configured to generate an acoustic signal, and a second acoustic marker located at the distal end of the retractable needle and configured to generate an acoustic signal. The acoustic markers allow, in conjunction with a Doppler ultrasound imaging system, identification and navigation of an injection catheter and delivering a needle to a desired anatomic target location.
