Radiofrequency Probes

For many years, only early-stage haemorrhoids were considered suitable for minimally invasive therapies, while more severe cases usually required surgical excision—often accompanied by significant discomfort and extended recovery times.

Advances in radiofrequency (RF) technology have transformed this approach. Today, patients across nearly all haemorrhoid grades can benefit from targeted, minimally invasive treatment.

For early-stage internal haemorrhoids (Grades I and II), the Sphera probe provides gentle surface coagulation, while for more advanced cases (Grades II to early IV), the Rafaelo® probe (Rafaelo® procedure) enables controlled thermocoagulation deep within the tissue. Together, these radiofrequency probes provide safe, effective, and tissue-preserving options for a wide spectrum of patients—without the need for traditional surgery.

Rafaelo needle probe

Rafaelo® is performed using the Rafaelo needle probe, which is inserted directly into the pile and used to deliver targeted radiofrequency energy. Unlike electrocautery, radiofrequency ablation causes minimal lateral heat dispersion; the 2 mm-diameter Rafaelo needle probe has a thermal radius of just 3 mm, ensuring precise thermocoagulation and optimal tissue preservation.
Its chrome nitride coating ensures a smooth, non-stick interaction with the tissue, preventing adhesion and allowing for safer, more controlled application.

Sphera ball probe

Patients with early-stage internal haemorrhoids can now benefit from minimally invasive RF ablation as well: the new Sphera ball probe is compatible with the same generators as the Rafaelo probe, but its spherical tip is specifically designed for surface coagulation of Grade 1 and 2 internal piles. The electrode’s chromium nitride coating helps prevent it from sticking to the delicate tissue while delivering radiofrequency energy.
