Not Applicable

Withdrawn

• Conditions: Chronic Low Back Pain
• Interventions: Device: Intracept System Ablation

• Registration Number: NCT03658018
• Lead Sponsor: Relievant Medsystems, Inc.

Brief Summary

Objective of study is to evaluate the procedural success rate, clinical effectiveness, and heath-economic profile using the Intercept Intraosseous Nerve Ablation System in adult subjects with chronic low back pain in the post-market setting

Detailed Description

This is a prospective, open-label, single-arm, single-center study. There is no randomization or blinding. Subjects will receive the Intercept System procedure to treat one or two motion segments at L3/L4, L4/L5, or L5/S1 as identified by Modic Type 1 or 2 changes.
