摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method of enrobing a product portion in polymer strands includes mounting at least one product portion on a holding device and passing the at least one product portion through a polymer enrobing zone. The polymer enrobing zone can include a flow of polymeric fibers produced by a polymer spray head. The polymer fibers can wraparound the at least one product portion to produce an enrobed product portion. The holding device can hold the at least one product portion by passing at least partially through the body of the product portion. At least a portion of the holding device is removed from the enrobed product portion. In some cases, the at least one product portion includes smokeless tobacco.

摘要： Embodiments of the invention generally include apparatus and methods for depositing nanowires in a predetermined pattern during an electrospinning process. An apparatus includes a nozzle for containing and ejecting a deposition material, and a voltage source coupled to the nozzle to eject the deposition material. One or more electric field shaping devices are positioned to shape the electric field adjacent to a substrate to control the trajectory of the ejected deposition material. The electric field shaping device converges an electric field at a point near the surface of the substrate to accurately deposit the deposition material on the substrate in a predetermined pattern. The methods include applying a voltage to a nozzle to eject an electrically-charged deposition material towards a substrate, and shaping one or more electric fields to control the trajectory of the electrically-charged deposition material. The deposition material is then deposited on the substrate in a predetermined pattern.
