ULTRASONIC LESION FEEDBACK, ANTIPOP MONITORING, AND FORCE DETECTION |
摘要 |
An ablation catheter comprises: an elongated catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis; a distal member disposed adjacent the distal end, the distal member including an ablation element to ablate a biological member; one or more acoustic transducers disposed in the distal member and each configured to direct an acoustic signal toward a respective target ablation region and receive reflection echoes therefrom; and an acoustic redirection member disposed in the distal member to at least partially redirect the acoustic signal from at least one of the acoustic transducers toward a tissue target. The distal member includes a most-distal portion, a proximal portion, and a deflectable portion between the most-distal portion and proximal portion to permit deflection between the most-distal portion and proximal portion of the distal member. The transducers and redirection member are mounted on opposite sides of the deflectable portion. |
