Inclusion Criteria: 1. Signed Informed Consent 2. Patients greater or equal to 18 years of age 3. Performance status 0-2 (Eastern Cooperative Oncology Group classification \[ECOG\]) 4. Willing to fulfill all follow-up visit requirements 5. Medically inoperable and operable secondary soft tissue lesion(s) of the lung 6. A maximum of two ipsilateral soft tissue lesions less than or equal to 2cm in the outer two-thirds of the lung and not closer than 1cm to the pleura. Lesion size must be measured with at least 2-dimensional imaging. Exclusion Criteria: 1. Scheduled concurrent procedure for the target soft tissue lesion(s) other than those that are lung-related 2.

Patient count less than or equal to 50,000/mm cubed 9. ASA (American Society of Anesthesiologists) score of greater than or equal to 4 10. Inability to tolerate anesthesia 11. Expected survival less than 6 months 12. Clinically significant hypertension 13. Chronic, continuous ventilator support, which uses bi-level positive airway pressure (PAP) to improve lung function for severe conditions (however, intermittent PAP, for non-pulmonary conditions, such as sleep apnea, is permitted) 14. Endobronchial soft tissue lesions proximal to the segmental airways 15. Imaging findings of active pulmonary infection 16. The patient was judged unsuitable for study participation by the Investigator for any other reason.
