In Vitro Blood-perfused Bovine Liver Model: A Physiologic Model for Evaluation of the Performance of Radiofrequency Ablation Devices

In the in vitro blood-perfused bovine liver model, the size of ablations produced by an RF ablation device are closer in size to those seen in porcine liver in vivo compared with the lesions produced in KH solution-perfused or nonperfused bovine liver.
