Abstract
Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.
Claims21
A method for manufacturing a scaffold for use in a surgical staple cartridge, the method comprising:
- forming a first knitted layer that comprises fibers of a first polymer, the first knitted layer being configured to mate with a cartridge deck;
- forming a second knitted layer that comprises the first polymer fibers;
- and
- interknitting spacer fibers with the first and second knitted layers so as to connect the first and second knitted layers together in a spaced parallel relation, the spacer fibers being formed of only a second polymer that is different than the first polymer, wherein the spacer fibers are integrated with and extending between the first and second knitted layers,
- wherein the first polymer fibers have a diameter that is different than a diameter of the second polymer fibers, and
- wherein the first polymer fibers have a first glass transition temperature and the second polymer fibers have a second glass transition temperature that is less than the first glass transition temperature.
