Tissue graft prosthesis devices containing juvenile or small diameter submucosa

Abstract

Described are preferred tissue graft materials that incorporate juvenile submucosa tissue from a warm-blooded vertebrate. Preferred materials incorporate juvenile small intestinal submucosa tissue from a mammal such as a porcine mammal, and the constructs are preferably in tubular form and utilized the isolated submucosa tissue in its native, intact tubular form. More preferred devices are multi-laminate and include the juvenile submucosa tissue in addition to at least one, and preferably several other layers providing increased strength or other advantageous properties to the construct.
