Abstract

Described are devices and methods for reinforcing a layer of living tissue, which when affixed to a tissue layer prior to surgical incision, reinforces the tissue to be incised, provides a fibro-conductive matrix to promote healing in a preferred plane, and provides for a subsequent closure and fluidic seal. A partially or entirely absorbable growth matrix is disclosed, comprising two adhesion-resistant layers enclosing a cellular conductive medium for promoting fibrosis in a preferred plane. The cellular conductive portion is partially or entirely sequestered from surrounding tissue. The device is constructed in a physiologic range of tensile strengths and elasticity suitable for closure of the pericardium, peritoneum, or other typically thin membranes enclosing organs in the body, whose function is to prevent adhesions between tissue surfaces normally in motion.
