The primary objective of this trial is to demonstrate the effectiveness of the powered vascular stapler for transection of the pulmonary artery (PA) and pulmonary vein (PV) during Video-Assisted Thoracoscopic Lobectomy.

Inclusion Criteria:

1. Subjects with a confirmed or suspected diagnosis of stage IA to stage IIB non-small cell lung cancer scheduled for lobectomy (Lung Cancer Staging per American Joint Committee on Cancer,7th Edition)7;
2. Subjects scheduled for VATS lobectomy in accordance with their institution's SOC;
3. Performance status 0-1 (Eastern Cooperative Oncology Group classification);
4. ASA score < 3;
5. No prior history of VATS or open lung surgery (on the lung in which the procedure will be performed);
6. Willing to give consent and comply with study-related evaluation and treatment schedule; and
7. 18-75 years of age (inclusive).

Exclusion Criteria:

1. Active (subject currently receiving systemic treatment) bacterial infection or fungal infection;
2. Systemic administration (intravenous or oral) of steroids, including herbal supplements that contain steroids (within 30 days prior to study procedure);
3. Uncontrolled diabetes mellitus;
4. End stage renal or liver disease;
5. History of severe cardiovascular disease;
6. FEV1% <50% or severe COPD;
7. Prior chemotherapy or radiation for lung cancer;
8. Scheduled concurrent surgical procedure other than diagnostic wedge resection followed by lobectomy (central venous access - e.g., port placement, mediastinoscopy with lymph node sampling, and VATS lymphadenectomy are allowed);
9. Robotic-assisted procedure;
10. Women who are pregnant or lactating at the time of screening;
11. Physical or psychological condition which would impair study participation;
12. The subject is judged unsuitable for study participation by the Investigator for any other reason;
13. Participation in any other investigational drug (within 30 days or 5 half-lives of an investigational drug) or device study; or
14. Unable or unwilling to attend follow-up visits and examinations.

All enrolled subjects who had a procedure completed and provided data on the number of surgical interventions.

Adverse events were collected from the time informed consent was signed through the final study visit which occurred approximately four weeks after the surgery was performed.

This was a single arm study with a limited sample size.
