An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.

The invention further provides a method of making the non-woven fabric as well as a filtered container or beverage capsule formed with the non-woven fabric.

The present application discloses a method for preparing microporous PVA fiber comprising the following steps: Step 1: preparing spinning solution, calcium hydroxide solution, and sodium sulfate solution; Step 2: cooling the spinning solution to 40-60° C., and adding a foaming agent thereto to provide the PVA spinning stock solution; Step 3: spinning into the sodium sulfate solution so that the fiber containing the reaction product of the foaming agent and the mirabilite is dehydrated to provide a primary PVA fiber; Step 4: reacting the fiber with the calcium hydroxide solution to provide a secondary fiber; Step 5: foaming and pore forming; and Step 6: cleaning and drying to provide the final product of microporous PVA fiber.

A knitted fabric for promoting heat dissipation is to be an insole and covers a wearer's skin when in use, and has two surface layers, an intermediate layer, and multiple channels. The two surface layers are disposed at a spaced interval, and include a first surface layer and a second surface layer oriented to the wearer's skin when the knitted fabric is in use. The second surface layer has multiple braids disposed parallelly, and each one of the multiple braids is straight and extends in a widthwise direction. The intermediate layer is formed with multiple monofilaments knitted between the two surface layers and divergently stretch out from each braid toward the first surface layer. Each monofilament intercrosses with another at a point near the first surface layer. A channel is formed among the intermediate layer and adjacent two said braids and has a V-shaped cross section.

A bone implant for enclosing bone material is provided. The bone implant comprises a woven or knit mesh having an inner surface and an outer surface opposing the inner surface and configured to receive a bone material when the inner surface of the mesh is in an open configuration. A plurality of projections are disposed on or in at least a portion of the inner surface of the mesh, the outer surface of the mesh or both the inner and outer surfaces of the mesh, the plurality of projections extending from at least the portion of the inner surface, the outer surface or both the inner and outer surfaces of the mesh and are configured to engage a section of the inner or outer surfaces of the mesh or both in a closed configuration so as to enclose the bone material.

Disclosed are a wet non-woven fabric, the use of the wet non-woven fabric as a supporting layer of a water treatment membrane, a method for preparing the wet non-woven fabric, and a water treatment membrane containing the wet non-woven fabric. The wet non-woven fabric has an average pore size of no greater than 20 .Math.m, a maximum pore size of no greater than 40 .Math.m, and a maximum pore size/average pore size ratio of no less than 1 and no greater than 12.

A method of manufacturing a graphene fiber is provided. The method includes preparing a source solution including graphene oxide, supplying the source solution into a base solution containing a foreign element to form a graphene oxide fiber, separating the graphene fiber from the base solution and cleaning and drying to obtain the graphene oxide fiber containing the foreign element, and performing thermal treatment to the dried graphene oxide fiber containing the foreign element to form a graphene fiber doped with the foreign element. Elongation percentage of the graphene fiber is adjusted by concentration and spinning rate of the source solution.

A method of preparing a ceramic fabric and ceramic matrix composite components constructed from the ceramic fabric include transforming ceramic tows, or ceramic fabrics, to varying degrees from a first tow geometry to a second tow geometry, thereby reducing a first dimension of the ceramic tows and increasing a second dimension of the ceramic tows orthogonal to the first dimension. Plies constructed with flattened tows, or as-received tows, have various inter-tow pore sizes that are arranged with increasing inter-tow pore size towards exterior surfaces of the preform structure.

A moisture-response deforming fabric includes 40 parts by weight to 70 parts by weight of an ordinary yarn and 30 parts by weight to 60 parts by weight of a moisture-response stretching nylon yarn. A water-vapour permeability index (imt) of the moisture-response deforming fabric is greater than or equal to 0.35 under a measurement of the validation FTTS-FP-161.

A multiple-layer knitted fabric includes: an inner composite layer formed with hydrophilic yarn and hydrophobic yarn adapted to be contacted with a wearer's skin: an outer dissipating layer formed with hydrophilic yarn or hydrophobic yarn adapted for dissipating moisture and heat outwardly: and a spacer layer integrally formed between the inner and outer layers and formed with hydrophilic yarn for absorbing the moisture of the wearer's sweat from the inner layer and temporarily storing the moisture in the spacer layer, through which the moisture is gradually outwardly transported into the outer layer and then dissipated into the outside atmosphere: thereby keeping the wearer's cool in summer and warm in winter for enforcing his or her comfortable wearing.
