For Physicians

Procedure Overview


“Our analysis indicates that Lap-RFA is associated with low complication rates, minimal EBL, and low reintervention rates. In addition, patients reported major improvement in their HRQL and symptom severity scores compared to reports of more traditional interventions, such as hysterectomy, myomectomy, and UAE.”

Outpatient laparoscopic procedure


Prep & Access — Outpatient, laparoscopic procedure that requires general anesthesia and two access points for a 5 mm standard laparoscope and a 10 mm laparoscopic intra-abdominal ultrasound probe. 1

Visualize — Physicians utilize both a laparoscopic and intra-abdominal ultrasound view to locate fibroids, visualize anatomy and confirm safety during the procedure.

Lap. Ultrasound & radiofrequency

Deploy — Physicians insert the Acessa handpiece tip into a fibroid and deploy 7 thin needle-like electrode arrays into the fibroid tissue, while confirming safe and proper placement with ultrasound guidance technology. Based on the length of the electrode array deployment, the system automatically calculates the dimensions of the treatment zone and the duration of the ablation.

Illustrative of tissue effect coagulative necrosis

Treat — Physicians treat the fibroids by pressing a footpedal which initiates radiofrequency energy to emit through the needle-like arrays. The steps are repeated with overlapping ablations. The physician repeats this process until every targeted fibroid is fully treated. The arrays are retracted into the handpiece shaft before the handpiece tip is withdrawn from the fibroid with coagulation.

The heat generated from the radiofrequency energy causes thermal destruction of the fibroid through coagulative necrosis. 1,24 The extracellular protein matrix of the fibroid is denatured and broken down into small fragments that are reabsorbed by the surrounding normal tissue, causing the previous fibroid mass to soften and shrink over time.

Finish — With visual and temperature cues, physicians can check that fibroids are fully treated before finishing the procedure.

Recovery & Post-Op — Postoperative pain is typically mild (NSAID, may include pelvic pain and cramping). 1,24 Most patients return to daily activities in 4- 5 days. 6,24

Symptom Relief — Fibroid symptoms, including heavy menstrual bleeding, urinary frequency, abdominal distension, and pelvic pain, typically resolve or significantly improve within 3 months and continue to improve over a year. 1, 8 Most patients experience long-term satisfaction and relief. 8
