20130110097 | METHODS OF CONDITIONING SHEET BIOPROSTHETIC TISSUE | 05-02-2013 |
20130116676 | METHODS OF CONDITIONING SHEET BIOPROSTHETIC TISSUE - Methods for the conditioning of bioprosthetic material employ bovine pericardial membrane. A laser directed at the fibrous surface of the membrane and moved relative thereto reduces the thickness of the membrane to a specific uniform thickness and smoothes the surface.
