The objective of this clinical study is to evaluate the safety of the Progel® PALS, including the Progel® Extended Applicator Spray Tips, in sealing or reducing intraoperative air leaks in patients undergoing video assisted or robotic assisted thoracoscopic (VATS/Robotic) surgeries.

The data collected in this clinical study will supplement the Approved PMA P010047 Progel® PALS product.

This is a prospective, open label, multi-center clinical study designed to assess the safety of the Progel® PALS product, including the Extended Applicator Spray Tip, when used in Video Assisted and Robotic Assisted Thoracoscopic Surgery. The study will treat approximately 105 evaluable subjects at up to 15 U.S. sites. All subjects will provide informed consent prior to enrollment in the study.

Patients who have met the initial screening criteria and who have a visible pleural air leak which requires treatment with a sealant, after standard closure techniques are used (standard sutures, staples or devices supplied by the hospital for thoracoscopic surgery) will be eligible for study participation. If the subject is treated, the surgeon will utilize Progel® PALS to the same sites originally treated with standard technique.

Inclusion Criteria:

• Subject is willing and able to provide written informed consent.
• Subject is scheduled for video assisted or robotic assisted thoracoscopic surgery for lung resection (i.e. lobectomy, bilobectomy, segmentectomy, and wedge resection/lung volume reduction), decortications or biopsy within 45 days of the screening evaluation.
• Subject is ≥18 years of age.
• Subject has a life expectancy ≥6 months.
• Following lung resection, subject has at least one or more visible intraoperative air leaks, after standard closure techniques are applied, that requires treatment with pleural sealant.
• Subject is willing and able to comply with the study procedures and complete the entire study as specified in the protocol, including the follow-up visits.

Exclusion Criteria:

• Subject has undergone previous lung resection or previous use of a sealant for air leaks.
• Subject has a serum creatinine ≥2.5 mg/dl at baseline or is currently on dialysis.
• Following lung resection, subject has intraoperative air leaks that require non-standard, visceral pleural closure (e.g. leak is too small or tissue is too fragile to use sutures/staples).
• Subject has any condition that, in the opinion of the Investigator, would preclude the use of the study device, or preclude the subject from completing the follow-up requirements.
• Subject has known allergy to human albumin or any component in the Progel® PALS product.
• Subject has an active or latent infection which is systemic or at the intended surgery site.
• Subject has necrotic or friable borders of the defect that will not support secure suture fixation if use of sutures is required.
• Subject is participating in another investigational drug or device trial.
• Subject is pregnant or has plans to become pregnant during the study period or is currently breastfeeding.
• Subject is part of the site personnel directly involved with this study.
• Subject is a family member of the investigational study staff.
