Abstract
The present disclosure relates to a hydrogel composition and methods of using the same. The hydrogel composition may include precursors that react with each other upon contact as well as precursors that react upon contact with an initiator. In embodiments, the resulting hydrogels may have varying levels of crosslinking with both denser and less dense regions.

1-9. (canceled)
A method of attaching mesh to tissue comprising:
- contacting a mesh comprising an initiated precursor comprising at least one vinyl group with a first reactive precursor comprising a multi-arm polyether possessing electrophilic groups, and a second reactive precursor comprising nucleophilic groups;
- contacting the mesh to tissue;
- allowing the first reactive precursor and the second reactive precursor to react to form a first hydrogel;
- and
- contacting the initiated precursor with an initiator to form a second hydrogel, wherein the second hydrogel secures the mesh to the tissue.
