New Study Found Neuwave With Ablation Confirmation Software Demonstrated Improved Procedural Outcomes


New Data Presented at CIRSE Expands Support for The Use of NEUWAVE™ Ablation Confirmation Software to Help Improve Microwave Ablation Procedure Outcomes

CINCINNATI – September 30, 2020 A new study found the use of the NEUWAVE™ System with Ablation Confirmation software demonstrated improved procedural outcomes during liver tumor ablation procedures. In this study, the information provided by the NEUWAVE Ablation Confirmation software resulted in probe repositioning in 20-23% of the procedures, 100% technical success and improved overall procedural outcomes.1

The study was published online in mid-September as part of the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) 2020 Summit. The study was sponsored by Ethicon*, a Johnson & Johnson Medical Devices** Company, and the manufacturer of the NEUWAVE Microwave Ablation System, a minimally invasive technology that uses heat transmitted through image-guided needle-like probes to destroy targeted soft tissue lesions in the liver, kidneys and lungs.  Read the study summary for more details.

“The NEUWAVE Ablation Confirmation helps improve precision and accuracy in ablation procedures, which is critical to achieving technical success. I believe this software will become standard practice as we seek to improve outcomes,” said Paul Laeseke, MD, PhD4, study co-author and an interventional radiologist at the University of Wisconsin - Madison.

The NEUWAVE Ablation Confirmation software is the only integrated in-procedure confirmation software on the market. The software assists physicians by improving visualization throughout the procedure and by helping define and lock target tumor volume, evaluate the exact proximity of the probe to the target and verify technical success to ensure full tumor and margin coverage. 

Previously, researchers from Memorial Sloan Kettering Cancer Center presented studies at both annual meetings for the Society of Interventional Oncology (SIO) and the Society of Interventional Radiology (SIR) highlighting their experience with the NEUWAVE Ablation Confirmation software. The studies demonstrated the software was superior at detecting margins of 5mm or less (38.5% detected) in ablated tumors versus standard CT scans alone (0% detected). In addition, the study found that the software had high sensitivity and specificity for predicting local tumor progression (100% / 92.3%).2

The NEUWAVE System is already the leader in Microwave Ablation in the United States and is growing rapidly throughout Europe and Asia.3 The addition of NEUWAVE Ablation Confirmation software is predicted to accelerate adoption.

With the promising results shown in this emerging evidence, Ethicon continues to invest in evidence to support the NEUWAVE Microwave Ablation System. Last year, the company launched a prospective study on NEUWAVE Ablation Confirmation as well as a global registry to collect and analyze real-world data on patients with soft tissue liver lesions ablated with the NEUWAVE System.
