A method is disclosed for altering an implantable layer for use with a surgical instrument which includes the steps of obtaining an implantable layer comprised at least partially from a material including a glass transition temperature and a melting temperature, wherein the implantable layer includes a first shape, heating the material to a temperature higher than the glass transition temperature and lower than the melting temperature, manipulating the implantable layer to a second shape different than the first shape, allowing the material to cool below the glass transition temperature, and releasing the implantable layer.
1. A method for altering a tissue thickness compensator for use with a surgical instrument, said method comprising the steps of: obtaining a tissue thickness compensator comprised at least partially from a material including a glass transition temperature and a melting temperature, wherein said tiss
1. A method for altering a tissue thickness compensator for use with a surgical instrument, said method comprising the steps of: obtaining a tissue thickness compensator comprised at least partially from a material including a glass transition temperature and a melting temperature, wherein said tissue thickness compensator comprises a first shape;heating said material to a temperature higher than said glass transition temperature and lower than said melting temperature;applying a modifying member to a tissue-facing side of said tissue thickness compensator;manipulating said tissue thickness compensator with said modifying member to a second shape different than said first shape by inducing a localized change in a portion of said tissue thickness compensator in contact with said modifying member;allowing said material to cool below said glass transition temperature; andreleasing said modifying member from said portion of said tissue thickness compensator. 2. The method of claim 1, wherein said step of obtaining said tissue thickness compensator comprises the steps of: obtaining a biocompatible polymer comprising a glass transition temperature and a melting temperature;dissolving said biocompatible polymer in a solvent to produce a solution; andlyophilizing said solution. 3. The method of claim 1, wherein said step of manipulating said tissue thickness compensator comprises applying at least one compressive force to said tissue thickness compensator. 4. The method of claim 1, wherein said step of manipulating said tissue thickness compensator comprises applying at least one tensile force to said tissue thickness compensator. 5. The method of claim 1, further comprising the step of actively cooling said manipulated tissue thickness compensator below said glass transition temperature. 6. A customized tissue thickness compensator for use with a surgical stapler, wherein said customized tissue thickness compensator is prepared by a process comprising the steps of: obtaining a tissue thickness compensator comprising a first shape;transitioning at least a portion of said tissue thickness compensator from an original state to a glassy state;applying a modifying member to a tissue-facing side of said tissue thickness compensator;manipulating said at least a portion of said tissue thickness compensator with said modifying member to a second shape by inducing a localized change in a portion of said tissue thickness compensator in contact with said modifying member;allowing said at least a portion of said tissue thickness compensator to return from said glassy state to a non-glassy state; andreleasing said modifying member from said at least a portion of said tissue thickness compensator. 7. The customized tissue thickness compensator of claim 6, wherein said step of obtaining said tissue thickness compensator comprises the steps of: obtaining a biocompatible polymer comprising a glass transition temperature and a melting temperature;dissolving said biocompatible polymer in a solvent to produce a solution; andlyophilizing said solution. 8. The customized tissue thickness compensator of claim 6, wherein said step of manipulating said at least a portion of said tissue thickness compensator comprises applying at least one compressive force to said at least a portion of said tissue thickness compensator. 9. The customized tissue thickness compensator of claim 6, wherein said step of manipulating said at least a portion of said tissue thickness compensator comprises applying at least one tensile force to said at least a portion of said tissue thickness compensator. 10. The customized tissue thickness compensator of claim 6, wherein said process comprises the step of actively cooling said at least a portion of said tissue thickness compensator to remove said at least a portion of said tissue thickness compensator from said glassy state to said non-glassy state. 11. The customized tissue thickness compensator of claim 6, wherein said process comprises the step of maintaining said manipulation of said at least a portion of said tissue thickness compensator for a period of time sufficient to permit said at least a portion of said tissue thickness compensator to maintain said manipulation. 12. The method of claim 1, wherein said second shape has a greater density than said first shape. 13. The customized tissue thickness compensator of claim 6, wherein the density of said second shape of said tissue thickness compensator is greater than the density of the first shape of said tissue thickness compensator.
