1. A surgical prosthesis comprising:
- a three-dimensional mesh comprising at least two types of yarn interlooped or intertwined to define at least two layers, wherein one of the at least two layers is substantially non-biodegradable and another of the at least two layers is substantially biodegradable; and
an adhesion barrier interconnected with the second, substantially biodegradable layer of the three-dimensional mesh.

20. A surgical prosthesis comprising:
-
a first layer formed substantially of a non-biodegradable yarn, the first layer defining a first outer surface of the surgical prosthesis;
a second layer formed substantially of a first biodegradable yarn, the second layer connected to the first layer with a second biodegradable yarn; and
an adhesion barrier embedded within the second layer, the adhesion barrier defining a second outer surface of the surgical prosthesis, wherein the first outer surface of the surgical prosthesis has a macroporous structure adapted to permit tissue ingrowth into the first layer and the second outer surface of the surgical prosthesis is adapted to minimize the formation of adhesion of tissue adjacent to the second outer surface. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of making a surgical prosthesis, the method comprising the steps of:
-
providing a fabric comprising a first layer formed substantially of non-biodegradable yarn and a second layer formed of biodegradable yarn;
providing a liquid formulation comprising macromers and an initiator;
placing the fabric within the liquid formulation such that the second layer is in fluid contact with the liquid formulation; and
exposing the liquid formulation to a light source. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A method of making a surgical prosthesis, the method comprising the steps of:
-
providing a fabric comprising a first layer formed substantially of non-biodegradable yarn and a second layer formed of biodegradable yarn;
providing a liquid formulation comprising a first polymer system, a second polymer system, and a photoinitiator;
placing the fabric over the liquid formulation such that the second layer is in fluid contact with the liquid formulation; and
exposing the liquid formulation to a light source to activate the photoinitiator so as to cause polymerization of at least one of the polymer systems in the liquid formulation. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48)
