A method of addressing a condition of a living body comprising the steps of using an energy beam to form a set of pores in a work piece biocompatible membrane. The pores should have a mean area of less than 500 &#x3bc;m through the biocompatible membrane, thereby producing a microporous membrane adapted to facilitate tissue in growth. This membrane is placed at least partially about an article that is adapted to be implanted in a living body, which is implanted into the living body, thereby addressing the condition.

Neovascularization promoting membrane for bioimplants

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 &#x3bc;m 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.
