What this research studies

Researchers are developing ultra-elastic hydrogel patches that stick immediately to the lung surface and stretch with breathing. In rat tests, they sealed holes by applying clotting proteins (fibrinogen and thrombin) on opposite sides of the patch so the clot closes leaks and the patch stays in place. The patches can carry medicines on both sides and could be placed over staple lines or injured lung areas during surgery. This grant supports refining the patch design and preclinical testing to move toward possible human trials.

Who could benefit from this research

Good fit: People having lung surgery such as lobectomy, segmentectomy, or wedge resection who are at risk for postoperative air leak.

Not a fit: People who are not undergoing lung surgery or whose air leaks come from deep internal lung problems not reachable by a surface patch may not benefit.

Why it matters

Potential benefit: If successful, the patches could prevent air leaks, reduce chest tube use and hospital stays, lower complications, and improve recovery after lung surgery.

How similar studies have performed: Some surgical sealants are already used clinically, but this ultra-elastic, adhesive hydrogel approach is new and so far has only shown success in animal studies.
