Kidney RFA

Transform treatment of renal tumors with a major upgrade to RFA technology.

Targeted Energy for Renal Tumors

With lower peak tissue temperatures than microwave and faster treatment times than cryoablation, the CRF RFA system can produce large, targeted ablations using a single electrode, with temperature controls that help preserve surrounding nephrons.3-5

Real-Time Audiovisual Feedback

The CRF RFA System is easy to use, with real-time feedback that makes it easier to monitor the ablation process and focus on the patient during procedure.

Rapid Procedures

With high power output, a sharp and steerable probe, and a coaxial option for pre-ablation biopsy, the CRF System can reduce procedure time even when ablating larger tumors.

Reproducible Results

The CRF RFA System’s optimized pulsing algorithm helps to ensure predictable ablation volumes and to limit overheating and charring of tissue.

Cambridge Interventional generator

Cooled Radiofrequency Electrodes

Paired with the powerful CRF generator, the CRF electrodes efficiently ablate renal tissue using active tip lengths of up to 5 cm.

Engineered for access and comfort

Our unique, low-profile, lightweight electrode hub and cable reduce hand fatigue, probe sag, and interference with surrounding anatomy and imaging equipment.

Peak versatility

Multiple sizes and tip lengths allow physicians to choose the best tool for the specific case and application.

Maximized efficiency

Sequentially ablate via multiple introducers using a single electrode.

Streamlined biopsy capabilities

Biopsy through the electrode’s coaxial introducer to reduce punctures and keep imaging clear.
Various angled electrodes for Kidney
