Abstract
A needle lattice is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. The needle lattice may be disposed on, for example, a surface of a roller or press. The needle lattice precisely places openings in any pattern and location, and on any textile that forms the graft material. The needle lattice can be heated to fuse the surrounding material of the openings of the textile to prevent movement of the textiles and to prevent collapse of the openings. All parameters of the openings, including varying density, patterns, and size of each opening, can be controlled, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel. The needle lattice can quickly form multiple openings within a graft material, allowing for quick manufacturing of the prosthesis.
