Pre-stressing devices incorporating materials subject to stress softening |
摘要 |
A method and apparatus for pre-stressing devices incorporating materials subject to stress softening is disclosed, as well as the resulting device. The method includes fabricating a heart valve with an inflow side and an outflow side. At least a portion of the heart valve includes a material subject to stress softening. The material experiences stress when a pressure differential occurs between the inflow side and the outflow side of the valve. The method includes creating a stress in the material prior to implantation in order to stabilize the stress/strain response of the material prior to implantation.
