Abstract: A device for sinus lift following a tearing of the Schneiderian membrane, comprising a biodegradable, multi-lumen balloon. The balloon comprises a first lumen and a second lumen. The first lumen, when inflated, forms a separation barrier and a posterior layer which are substantially perpendicular to one another and extend along a length of the balloon. The second lumen defined by an inferior layer comprising perforations to enable a bone graft formed in the second lumen to mesh with the bony floor of the maxillary sinus. The balloon comprises an inlet cannula in fluid communication with the first lumen, to enable inflation of the first lumen. The balloon comprises at least one connector attached to or integrally formed with the balloon, and adapted or configured to anchor the balloon medially to a rim of a preformed lateral opening in the maxillary sinus.
