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.

Abstract
A method of manufacturing a tubular medical implant is provided. The method includes forming a hollow first tube with a first diameter and a first plurality of pores formed thereon and a hollow second tube with a second unstretched diameter and a second plurality of pores formed thereon. The second unstretched diameter is greater than the first diameter. At least a portion of the first tube slides within the second tube to create an overlapped area of the first tube and the second tube. The first tube and second tube are then bonded together in the overlapped area.
