NOLA (NeuWave Observational Liver Ablation) Registry

This is a multicenter, observational registry that follows patients for a total of 5

years from the date of the first liver ablation procedure with the NEUWAVE Microwave

Ablation System. The data gathered from participating sites will be available to be

analyzed to develop ablation parameter guidance for ablation approaches under varying

patient liver tissue conditions and liver lesions.

This is an "umbrella registry," which was included as an optional component in other

NEUWAVE studies; hence, data from consenting patients who are or will be enrolled in

other NEUWAVE soft tissue liver lesion ablation studies will be included in this

registry. All other patients will be enrolled and followed prospectively, enrolled

retrospectively with prospective, longitudinal follow up, or enrolled retrospectively

with all retrospective follow up.

Enrollment for this study will include up to 1,500 patients throughout the world who

underwent or are scheduled to undergo microwave ablation of one or more soft tissue liver

lesions using the NEUWAVE Microwave Ablation System or the NEUWAVE Microwave Ablation

System with Ablation Confirmation.
