Abstract
A laser is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. A feature of utilizing a laser to create the openings for tissue integration builds from its tunability. More particularly, the laser precisely places openings in any pattern and location, and on any textile that forms the graft material. Further, the power and focus of the laser is precisely adjusted to control the diameter and shape of the openings. All parameters of the openings can be controlled at will, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel.
