  • Blood flow reestablishment determination
    Publication number: 20060106308
    Abstract: A method for monitoring a clot dissolution treatment in a patient's vasculature comprises positioning a catheter at a treatment site in the patient's vasculature. The method further comprises performing a clot dissolution treatment at the treatment site. The clot dissolution treatment comprises delivering ultrasonic energy and a therapeutic compound from the catheter to the treatment site such that a clot located at the treatment site at least partially dissolves. The method further comprises delivering a thermal measurement signal from a first portion of the catheter to the treatment site during the clot dissolution treatment. The method further comprises receiving the thermal measurement signal at a second portion of the catheter. The method further comprises comparing the delivered thermal measurement signal with the received thermal measurement signal to evaluate a blood flow rate at the treatment site.
