Abstract:
A method for polishing surfaces of a cylindrical radially expandable surgical stent including the steps of:selecting an abrasiveness for particles within a fluid abrasive media; providing a source of the fluid abrasive media; orienting the radially expandable surgical stent with a central axis thereof extending in an axial direction; subjecting the fluid abrasive media to elevated pressure substantially between 300 and 800 p.s.i.; and flowing the abrasive media past the radially expandable surgical stent in an axial direction with the abrasive media coming into physical contact with the surface of the radially expandable surgical stent, wherein the step of flowing includes maintaining the flowing past an inner stent surface for a length of time sufficient to abrade the edges of the inner stent surface until said edges are streamlined in shape, and maintaining the flowing past an outer stent surface for a length of time sufficient only to polish the outer stent surface.
