Abstract
A hernia repair prosthesis with an occlusive member for inserting into and/or backing the herniated tissue. The occlusive member is convertible from a first configuration with a first axial length and first major radial extent to a second configuration with a second axial length and a second major radial extent. The second axial length is less than the first axial length and the second major radial extent is larger than the first major radial extent. The occlusive member has a pair of subsections, each having an apex, lands and pleats and each flaring outwardly therefrom towards a terminal end. The apexes are disposed at opposite ends of the occlusive member with the terminal ends overlapping. The pair of subsections are conjoined proximate the overlapping terminal ends. The terminal end of one or both of the subsections may be in the form of a conic flange mimicking the lands and pleats of the other subsection providing automatic alignment and nesting to aid in the attachment of the two subsections. In accordance with methods for forming the subsections, a surgical fabric is thermoset on a male die and may be stretched or heat shrunk to aid in conforming the surgical fabric to the…
