Abstract
A method of sealing a resected surface of an organ includes applying a synthetic matrix to a resected surface of an organ, and applying an adhesive on the synthetic matrix so that the adhesive penetrates through interstices of the synthetic matrix for contacting an interface between the synthetic matrix and the resected surface of the organ. The method includes curing the adhesive for bonding the synthetic matrix to the resected surface of the organ. The synthetic matrix is a non-woven mesh made of polyglactin 910 or any other synthetic or non-synthetic fabric having a similar porosity or density. The adhesive is a biosynthetic or a synthetic adhesive. After penetrating through the pores of the synthetic matrix and curing, the cured biosynthetic or synthetic adhesive mechanically interlocks with the synthetic matrix for adhering the synthetic matrix to the tissue for creating a sealing barrier.
