This study looks at how safe and effective the ECHELON 3000 Stapler is for surgeries. A stapler, in this case, is a tool used by doctors to close cuts made during surgery. The study involves people having a laparoscopic sleeve gastrectomy (a type of weight-loss surgery) or lung resection (removing part of the lung). These surgeries may be done using a camera and small cuts, or a more open method.

Adults and kids can join if they agree or have their parents' permission. People can't join if they have health issues that might affect their recovery, if they need a second surgery in the same area, or if they are taking medicines that could affect healing.

• The study checks the stapler's performance during surgeries.
• You must attend all appointments and follow the study plan.
• Some people might not be allowed to join due to health reasons or other studies.
