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.

A fiber with metal ions excited by luminous energy and a manufacturing method thereof are provided. The method includes: adding dry copper nanopowder with a particle size not more than 48 nm after mixing to a fiber slurry, to form a first mixed liquid; mixing and stirring the first mixed liquid and an additive, and performing an electrochemical reaction, to form a second mixed liquid, where the additive contains at least one of graphene, Ge ions, and Zr ions; performing energy exciting on the second mixed liquid, to form a mixed material; drying the mixed material, to remove moisture contained in the mixed material; extruding at least one fibril from the mixed material by using a spinning device; passing the at least one fibril through a plurality of rollers and performing stretching; and performing cooling and shaping on at least one stretched fibril, to form a final fiber product.

Fibers are clad with a responsive liquid crystal material and a polymer. The clad fibers may be useful for advanced textiles and wearable sensors.

A thermoplastic polyurethane coated yarn having excellent adhesive strength in which hydrophobic nano-silica is mixed. The nano-silica is contained in the range of 0.2-5 parts per hundred resin (phr) and the nano-silica having a primary particle size of in a range of 1-100 nm. The thermoplastic polyurethane coating yarn mixed with the hydrophobic nano-silica of the present invention is uniformly coated with a thermoplastic polyurethane resin containing nano-silica containing a hydrophobic functional group on the surface of the core yarn, whereby the core yarn is biased to one side. Since no coating or uncoating occurs, the product quality and productivity are excellent, in addition to excellent durability and wear resistance of the thermoplastic polyurethane, mechanical strength and chemical resistance are improved.

Bi— or multicomponent fibre (3) comprising a reinforcing core (1) of a first material and at least one sheath (2) of a second, thermoplastic or pre-polymerized thermoset material, for the manufacturing of composite parts, the matrix of which composite parts consists of the material of said sheath (2), wherein said first material has a degradation temperature, ignition temperature, glass transition temperature, melting temperature or liquidus temperature which is higher than the melting temperature, flowing temperature, r softening temperature of said second, thermoplastic or pre-polymerized thermoset material, wherein said reinforcing core (1) has a core volume fraction (v.sub.f) defined as the volume fraction of the reinforcing core (1) in the bi- or multicomponent fibre (3), which is in the range of 0.3-0.8, and wherein along a longitudinal axis (Z) of the bi- or multicomponent fibre outer surface (4) of the sheath (2) has a corrugated, preferably irregular corrugated shape.

The present invention implements a set of grooves/ridges created on Ti at the circumferential direction to increase surface area of implant in contact with bone. These grooves/ridges protect nanofiber matrix (NFM) made with Polycaprolactone (PCL) electrospun nanofiber (ENF) and collagen at the groove from physiological loading. Controlled fabrication of a ridge made with titanium nitride (TiN) around the circumference of Ti is provided using a plasma nitride deposition technique. PCL ENF may be deposited along the sub-micrometer grooves using the electrospin setup disclosed. The method provides for fabrication of microgroove on Ti using machining or TiN deposition and filling the microgrooves with the NFM. This method has proven through experimentation to be successful in increasing in vivo mechanical stability and promoting osseointegration on Ti implants. The immobilization of MgO NP and FN with the PCL-CG NFM on microgrooved Ti as provided in the invention optimizes biological performances of Ti.
