Summary
This study introduces a novel radiofrequency ablation (RFA) device allowing bipolar and multipolar applications without grounding pads. Clinical trials demonstrated its use in liver tumors, osteoid osteoma, and renal cell cancer.
Area of Science:
- Medical Devices
- Oncology
- Surgical Technology
Background:
- Monopolar radiofrequency ablation (RFA) necessitates grounding pads, complicating procedures.
- Bipolar RFA confines the electrical circuit within the probe, eliminating the need for grounding pads.
Purpose of the Study:
- To report the first clinical application of a new RFA device.
- To evaluate the device's capability for bipolar and multipolar ablation.
Main Methods:
- The new RFA device allows for both bipolar (single probe) and multipolar (up to 3 probes) ablation.
- Clinical applications were performed in patients with liver tumors, osteoid osteoma, and renal cell cancer.
Main Results:
- The study reports successful bi- and multipolar RFA applications.
- The device was utilized in 9 patients with liver tumors, 2 with osteoid osteoma, and 1 with renal cell cancer.
Conclusions:
- The novel RFA device offers versatile bipolar and multipolar ablation capabilities.
- This technology eliminates the need for grounding pads, potentially simplifying RFA procedures.
