Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The iRF System is a percutaneous, catheter-based device which uses RF energy to circumferentially denervate the sympathetic nerves surrounding the common hepatic artery (CHA) and the renal arteries while minimizing injury to the arterial wall. The iRF System consists of the following components:
1. Single-use, monopolar, iRF Catheter that contains four (4) electrodes; provided sterile
2. Reusable, Radiofrequency Generator (RFG) with an Integrated Syringe Pump
3. Single-use, Generator Accessory Kit that contains a Syringe Cassette, two (2) tubing sets, and a waste collection bag, provided sterile
4. Single-use, Extension Cable, provided sterile

This procedure will be completed by an Interventional Cardiologist/Radiologist that has been trained on the device. It will occur in a catheterization laboratory or appropriate surgical setting. Up to 2 ablations will be administered during one procedure which will last no more than 2 hours.

Clinical observation and monitoring by the treating physician of the iRF system will be conducted throughout the procedure. The generator will also display system progress.
Each denervation cycle will provide 6 Watts of energy for 150 seconds to the common hepatic artery. Up to 2 cycles can be administered per procedure.
