Abstract
A method is disclosed for changing the spring rate of an implantable layer for use with a surgical instrument which includes the steps of obtaining an implantable layer having a first spring rate, wherein the implantable layer is at least partially comprised of a material having a glass transition temperature and a melting temperature, heating the implantable layer to a temperature higher than the glass transition temperature and lower than the melting temperature, deforming the implantable layer to change the first spring rate to a second spring rate, wherein the second spring rate is different than the first spring rate, allowing the implantable layer to cool below the glass transition temperature, and releasing the implantable layer.
