Abstract

Abstract Prosthetic tissue grafts formed of chemically cross-linked collagenous material wherein a first region of the graft (32) is cross-linked to a a first cross-link density and a second region of the graft (32) is cross-linked to a second cross-link density. The desired regionalized variations in cross-link density of the collageneous graft (32) may be accomplished by exposing specific portions or regions of the graft (32) to different fixative compositions and/or fixative concentrations and/or fixative reaction conditions (e.g., pH, temperature, pressure, exposure time).
