Patent ID: 8613944

Claim:
A method for separating tissue comprising: providing a first composition comprising a polymerizable material; providing a second composition comprising a polymerization initiator; disposing the first composition at a first site beneath a first soft tissue layer, the first site comprising an interfacial region between the first tissue layer and an adjacent second soft tissue layer; disposing the second composition at the first site; and polymerizing the polymerizable material at the first site, thereby separating the first tissue layer from the second tissue layer and forming a gap between the tissue layers of about 1 mm to about 10 mm, the separation of the first and second tissue layers being at least partially caused by the polymerization of the polymerizable material at the first site, wherein the polymerizable material comprises a polymer or oligomer of Formula (I): wherein R 8 is R 9 is x and y are integers independently ranging from 1 to 100; and z is an integer ranging from 1 to 20.
