How the bipolar electrode works in biliary RFA

ELRA^TM is a bipolar RF electrode that enables RF energy delivery between two closely spaced electrodes. This configuration allows for targeted ablation of tissue within the biliary ducts, reducing thermal injury to surrounding structures. The electrode is often used in combination with an endoscopic biliary stent. The goal is to restore duct patency and ensure proper bile drainage.

Uncompromised treatment

Percutaneous approach

Dedicated generator

When paired with the VIVA combo RF Generator, ELRA ^TM confirms the completion of an endoluminal ablation. Further, it prevents the over-application of energy via real-time impedance monitoring.

Temperature sensing

The VIVA combo RF Generator’s unique Temperature Sensing System enables ELRA to detect temperatures. It will automatically shut off upon achieving successful ablation or in case of inadequate contact.

A portfolio of sizes

The ELRA ^TM electrode features a range of ablative lengths, including 11mm, 18mm, 22mm, and 33mm. This caters to diverse anatomies and stricture locations. Furthermore, it ensures versatile treatment options for various indications.

Easy navigation

With a 7FR catheter and conical tip, ELRA enables seamless navigation through narrow ducts. You’ll achieve easy navigation in even the most complex anatomies.

Frequently asked questions

What is a bipolar electrode?

A bipolar electrode delivers energy between two poles on the same catheter tip. This offers more precise ablation in small, delicate structures like the biliary ducts.

How is RFA used in biliary duct obstruction treatment?

RFA helps ablate malignant tissue within the bile ducts, which can restore ductal patency before placing a stent.
