Brief Summary:

ROSTRA is an international, prospective, non-randomized, single-arm, multi-center, and post-market study to collect real-world safety and effectiveness data on Abbott's IonicRF™Generator and compatible RFA accessories. This post-market study is intended to satisfy EU MDR requirements.

The study will enroll up to 180 subjects at up to 10 sites in Europe and the United States.

The total duration of the study is expected to be 19 months, including enrollment, data collection from all subjects, and study closeout.

Condition or disease Intervention/treatment
Pain Device: IonicRF Generator andcompatible accessories

Layout table for study information
Study Type : Observational
Actual Enrollment : 184 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Real-World Outcomes Study on Subjects Treated With Radiofrequency Ablation
Actual Study Start Date : June 29, 2021
Actual Primary Completion Date : March 8, 2023
Estimated Study Completion Date : April 21, 2023

Group/Cohort Intervention/treatment
IonicRF Generator and compatible accessories
IonicRF Radiofrequency Generator, along with any country-specific market-released accessory (i.e. electrode, cannula, grounding pad, and adaptor cable) compatible with the IonicRF Generator will be used.
Device: IonicRF Generator andcompatible accessories
Participants will recieve IonicRFRF lesion generator, along with any country-specific market-released accessory (i.e. electrode,cannula, grounding pad, and adaptor cable) compatible with theIonicRF Generator

Primary Outcome Measures :
  1. Primary effectiveness endpoint: Relative change in Numeric Rating Scale (NRS) from baseline to 3 months follow-up visit [ Time Frame: Baseline to 3 months ]
    The pain NRS consists of 1 question that will be asked by interviewing the subjects. Patients will be asked to rate, from 0 (no pain) to 10 (worst imaginable pain), their average pain over the past 24 hours specific to the area(s) of chronic pain being treated. A higher score indicates greater pain intensity.

  2. Primary Safety Endpoint: Incidence of device- and procedure-related serious adverse events [ Time Frame: At 3 months ]
    The device- and procedure-related serious adverse events will be summarized as frequency, proportion and number of events per patient years of follow-up.
