Abstract
Sheet materials for cardiovascular and other prosthetic implants are fabricated of synthetic elastomers. These materials are characterized by molecular configurations that produce a nonlinear tensile modulus characteristic similar in shape to that of natural tissue. Selected elastomers, when formed as sheet material of appropriate geometrical configuration, promote the formation of natural tissue thereon which is appropriate for the mechanical characteristics desired.
