The objective of this study is to collect collect real-world data for the Ion endoluminal system.

This is a prospective, observational, multi-center, single-arm study to collect real-world data evaluating procedural characteristics and short- and long-term clinical outcomes following the use of the CE-marked Ion endoluminal system for elective lung nodule biopsies and/or localization procedures. It is a post-market study using the device per the approved indications. All patients will be enrolled per the protocol eligibility criteria. Enrollment for this study will conclude when approximately 1,200 patients have had a nodule biopsy and/or localization procedure attempted or performed.
