Surface structure for use as stent or fiber patch, has fibers adhered with one another and broken by ultrasonic treatment using ultrasonic generator, and stent drawn over arbor, where surface of arbor possesses small surface roughness

摘要

The surface structure has fibers that are adhered with one another, where the fibers are broken by an ultrasonic treatment using an ultrasonic generator (4), and broken lines are arranged in a statistically distributed manner. The surface structure exhibits an inner side, which is smoother than its exterior, and exhibits axial and tangential elasticity. A stent (1) is drawn over an arbor (2), and a surface (3) of the arbor possesses a small surface roughness. An independent claim is also included for a method for manufacturing a surface structure.
