Abstract:
1. A method for closing a passageway in a body of a patient, comprising: providing a closure device suitable for delivery to the body passageway, said closure device comprising a remodelable collagenous extracellular matrix sheet material, the extracellular matrix sheet material being isolated as a sheet material from a collagenous-based tissue source, the remodelable collagenous extracellular matrix sheet material being rolled or folded to provide a closure device construct in which the remodelable collagenous extracellular matrix sheet material spans the entirety of the length of the closure device construct and provides extracellular matrix material extending across the full width of the closure device construct prior to delivery with adjacent layers of the extracellular matrix sheet material contacting one another in the construct, the closure device construct being sized to occlude the passageway and the remodelable collagenous extracellular matrix sheet material being effective upon implantation of the closure device construct to provide new tissue growth in the body passageway for filling the passageway with tissue of the patient, wherein the isolated extracellular matrix sheet material has not been subjected to crosslinking; and inserting the closure device in the passageway.
