This study looks at how safe and effective the **ECHELON 3000 Stapler** is during certain surgeries. This stapler is a tool used to close cuts during surgery. The study focuses on people having either a laparoscopic sleeve gastrectomy (a surgery to help lose weight) or a lung resection (surgery to remove part of the lung). These surgeries can be done with a camera (video-assisted) or by opening the area.

Both adults and children can join the study if they meet specific criteria. For adults, they must agree to participate and follow all study rules. For children, their parent or guardian must agree, and the child must understand what's involved if they're old enough. However, people with certain medical conditions or those who need a repeated surgery at the same place cannot participate.

- The study requires participation in evaluations and visits according to a schedule.
- Only people whose primary procedure uses the ECHELON 3000 Stapler can join.
- There are risks if you have certain medical conditions or are taking specific medications.
