Porous tissue ingrowth structure
First Claim
1. A three-dimensional scaffold for a medical implant, the scaffold comprising a plurality of layers bonded to each other and each said layer having a top surface and a bottom surface, each of said layers having a plurality of pores extending through said top surface to said bottom surface, each said layer having a first pore pattern of said plurality of pores at said top surface and a different, second pore pattern at said bottom surface, said first pore pattern and said second pore pattern partially overlapping within each said layer, wherein adjacent said surfaces of at least three adjacent said layers having a substantially identical pore pattern aligning to interconnect said plurality of pores of said at least three adjacent layers and form a continuous porosity through said at least three adjacent said layers.

Abstract
A three-dimensional scaffold for a medical implant includes a plurality of layers bonded to each other. Each layer has a top surface and a bottom surface and a plurality of pores extending from the top surface to the bottom surface. Each layer has a first pore pattern of the pores at the top surface and a different, second pore pattern at the bottom surface. Adjacent surfaces of at least three adjacent layers have a substantially identical pore pattern aligning to interconnect the pores of the at least three adjacent layers to form a continuous porosity through the at least three adjacent said layers.

21. A method of manufacturing a scaffold for a medical implant, the method comprising the steps of:
-
providing a plurality of layers of a biocompatible material having a top surface and a bottom surface; creating a plurality of pores in said plurality of layers of biocompatible material such that each of said layers has a plurality of pores extending through said top surface to said bottom surface, a first pore pattern of said plurality of pores at said top surface of each of said layers being different than a second pore pattern of said bottom surface of each of said layers, and said first pore pattern and said second pore pattern partially overlap within each said layer; and bonding said plurality of layers together such that adjacent said surfaces of at least three adjacent said layers have a substantially identical pore pattern aligning to interconnect said plurality of pores of said at least three layers forming a continuous porosity through said at least three adjacent said layers.
