A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

An object of the present invention is to provide an apparatus and method for producing a nanofiber by using a melt blown method improving productivity.

A pellet-shaped raw material (resin) fed into a hopper 2 is supplied and melted in a heating cylinder 3 heated by a heater 4, and sent to a front part of the heating cylinder 3 by a screw 5 rotated by a motor 6. The heating cylinder 3 is provided with a head portion 7, and a high-pressure gas is ejected from the gas ejection hole 71 provided at a center of the head portion 7. The molten resin sent to an end of the heating cylinder 3 is discharged from a resin discharge hole 73 having six superfine tubes provided in a downstream side of the resin ejection hole 73 through inside of the head portion 7. The molten resin discharged from the resin discharge hole 73 is elongated and a fiber having nanometer-order diameter can be formed.

Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.

The present disclosure relates to a seat element, in particular, a headrest for a vehicle seat, the seat element comprising at least one support bar made of metal, a first layer provided at an exterior surface of the support bar, and a cushion made of an upholstery material. Hereby, the first layer is formed by blowing on first fibers made of plastics which are thermally welded directly or indirectly to the exterior surface. At least part of the first fibers extends away from the exterior surface and/or the first layer towards the outside into the upholstery material and is thermally cross-linked with the upholstery material, in particular, blown-on further fibers.

The present invention relates to a reinforcement material for textiles consisting of a non-woven support made of melt-spun polymer fibers and a hot-melt adhesive composition applied thereto, and to the use thereof.

Fluorine-free small molecule additives of structure where X.sup.1 and X.sup.2 are independently hydrocarbyl or heterohydrocarbyl; and Q and Q are independently Si(OSi(CH.sub.3).sub.3).sub.3 or (OSi(CH.sub.3).sub.2).sub.nOSi(CH.sub.3).sub.3 and where n is an integer from 0 to 30, inclusive for use in solid-state formulations, e.g., thermoplastic articles, for use in low hysteresis water repellent applications. Methods of preparing such compositions and additives.

A compressible adjunct is used with a surgical instrument. The compressible adjunct includes a hollow fibrous construct and a core fibrous construct housed within the hollow fibrous construct, wherein the hollow fibrous construct comprises at least one biocompatible material that has experienced at least one transition from a more ordered phase to a less ordered phase in response to heating the hollow fibrous construct to a predetermined temperature.

A surgical stapling instrument including staples and an implantable layer is disclosed. The implantable layer comprises fibers which have undergone a kinking process. The kinked fibers, once interwoven together, create a resilient body that can dynamically adapt to the thickness of the tissue captured within the staples.

A staple cartridge assembly is disclosed which comprises a cartridge body and an implantable layer. The implantable layer includes fibers comprised of a first material and a second material. The first material and the second material have different glass transition temperatures. After the fibers comprised of the first material and the second material have been intermixed or interwoven, the layer is exposed to a temperature which exceeds the lower of the two glass transition temperatures. This heating process causes the layer to constrict and increase in thickness. The layer, when implanted, can compensate for variations in tissue thickness within the staples.

A staple cartridge assembly is used with a surgical stapler. The staple cartridge assembly includes a staple cartridge including a cartridge body, a cartridge deck, and a plurality of staples deployable from the cartridge body through the cartridge deck. The staple cartridge assembly includes a compressible adjunct positionable against the cartridge deck. The compressible adjunct includes a plurality of unaltered fibers and a plurality of altered fibers that are melted and resolidified. The unaltered fibers include a first fiber including a first fiber portion and a second fiber including a second fiber portion extending over the first fiber portion. The compressible adjunct further includes a node which comprises the first fiber portion, the second fiber portion, and at least a portion of the plurality of altered fibers, wherein the at least a portion of the plurality of altered fibers affixes the first fiber portion and the second fiber portion.
