    Abstract: A method of assembling a prosthetic valve using sheets of material, such as pericardium material, polymer or bioengineered film, or other material. The method provides an accurate and repeatable system of making pericardial valves in which sheets or pieces of material are held securely in place relative to each other throughout the steps of assembling the valve. In addition, methods of the present invention include maintaining consistent alignment of the fixtures and pericardium material throughout the valve assembly process and utilize features that make the tooling components easy to assemble and handle. Certain aspects of the invention can be used to help establish a repeatable sewing and cutting technique for creating a pattern shape for valve leaflets, establishing stitch lengths, and determining the exact placement of stitches.

    Abstract translation: 使用诸如心包材料,聚合物或生物工程薄膜或其他材料的材料片组装人造瓣的方法。 该方法提供精确和可重复的制造心包瓣膜的系统,其中片材或片材在组装阀门的整个步骤中相对于彼此牢固地保持在适当的位置。 此外,本发明的方法包括在整个阀门组装过程中保持固定装置和心包膜材料的一致的对准,并利用使加工组件易于组装和处理的特征。 本发明的某些方面可以用于建立可重复的缝合和切割技术,以创建用于瓣叶的图案形状,建立针迹长度以及确定针迹的确切位置。
