Intraosseous Basivertebral Nerve Ablation for the Treatment of Chronic Low Back Pain

Study Overview
=================
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.
