- heating a cartridge deck;
- and
- positioning a knitted elastically deformable, bioabsorbable scaffold against a surface of the cartridge deck, the scaffold comprising:
- first and second knitted layers each having fibers of a first type and fibers of a second type, wherein the first type of fibers being predominantly present, wherein the first type of fibers have a first glass transition temperature and the second type of fibers have a second glass transition temperature that is less than the first glass transition temperature;
- and
- a support layer disposed between the first and second knitted layers, the support layer being formed of the second type of fibers,
- wherein the cartridge deck is heated to a temperature of at least the second glass transition temperature.
