摘要

An imaging assembly comprises a catheter having a distal end and a proximal end, an ablation tip at the distal end of the catheter, and an imaging device disposed within the ablation tip. The catheter defines a catheter lumen that extends from the proximal end to the distal end. The catheter is configured and arranged for insertion into a body lumen such as a blood vessel or heart chamber. The ablation tip has a wall that defines a lumen in communication with the lumen of the catheter. The imaging device is disposed within the lumen of the ablation tip, and is configured to transmit pulsed acoustic waves for generating images of body tissue at a target ablation site within the body.
