Endoluminal Radiofrequency Ablation: Biliary RFA

A safe alternative to endoluminal surgery for unresectable endoluminal structures

Automatic temperature-controlled endoluminal ablation machine for biliary RFA

STARmed has taken RFA to the next level by introducing ELRA^TM. Our Endoluminal Radiofrequency Ablation machine & catheter helps patients with unresectable endoluminal hepatic, biliary, or pancreatic lesions. It is a flexible RFA electrode with an automatic Temperature Sensing System. Ultimately, ELRA^TM offers interventional radiologists a minimally invasive palliative care option to enhance patients’ quality of life.

of patients will have stent occlusion in the first 6 to 8 months.

A percutaneous approach to endoluminal ablation

The ELRA Electrode is an innovative RFA catheter inserted over the wire (OTW). It’s used to ablate tissues in the hepatopancreatobiliary ducts. ELRA was designed to effectively clear obstructions and tumor growth through a percutaneous approach.

Complete biliary endoluminal ablation

Under fluoroscopic guidance, the ELRA electrode is advanced into the targeted segment of the duct to achieve endoluminal ablations.⁴ With 4 varying exposure lengths, ELRA completes ablations for varying lengths of stricture safely and effectively.⁵

Clinically proven results

According to multiple prospective single or multicenter studies, temperature-controlled intraductal RFA using the ELRA platform appeared feasible and safe with acceptable biliary patency. Temperature-controlled RFA avoids excessive heating and significant vessel or bile duct injury. ^6,7

Versatile applications

RFA produces promising results in patients with a variety of gastrointestinal and hepatopancreatobiliary pathologies. Thus, physicians have been exploring different applications of ELRA to enhance palliative care for patients. This includes its role in the treatment of biliary strictures, a key focus in hepatobiliary lesions radiology.
