ABSTRACT:
A method of producing a biocompatible microporous membrane comprising the steps of providing a biocompatible membrane and using an energy beam to form a set of pores having a minor axis of less than 15 μm through the biocompatible membrane. One embodiment includes the steps of producing a first layer of material, defining a first set of pores; producing a second layer of material, defining a second set of pores and wherein the second set of pores is defined so as to cooperatively engage the first set of pores; and aligning and joining the first layer of material to the second layer of material to form a laminated membrane, having through-passageways formed by the first set of pores at least partially aligned with the second set of pores.
