1. A method of manufacturing a tubular medical implant, comprising the steps of:

  • forming a hollow first tube having a first diameter and a first plurality of pores formed thereon;

    forming a hollow second tube having a second unstretched diameter and a second plurality of pores formed thereon, said second unstretched diameter being greater than said first diameter;

    sliding at least a portion of said first tube within said second tube to create an overlapped area of said first tube and said second tube;

    aligning at least one of said first plurality of pores with at least one of said second plurality of pores to form at least one implant pore;

    placing a non-porous support rod within said first tube; and

    compressing said first tube and said second tube toward said support rod at a bonding temperature to form a bonded tube such that said second tube is unstretched after bonding and said at least one implant pore extends completely through a formed tube wall of said bonded tube.
