20170275783 · 2017-09-28 ·

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.

A method for producing a balloon for a balloon catheter includes providing the balloon that has an outer surface. A solution including a solvent and a polymer is used to deposit the polymer onto the surface and form a surface coating of the polymer.

Small diameter, high strength, low elongation, creep resistant, abrasion resistant braided structure

A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.

WOVEN RETENTION DEVICES, SYSTEMS AND METHODS

A woven retention device for interfacing with a bone surface includes a sleeve body that can surround a fastener, a proximal end receiving the fastener, and a distal end. The sleeve body includes interwoven monofilaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. In a first state of the sleeve body, the protuberances are arranged in a predetermined spatial relationship and each protuberance has a thickness measured in a radial direction of the sleeve body. In a second state when a fastener is inserted into the tubular lattice, pressure from the fastener is transmitted to the tubular lattice such that the spatial relationship of the protuberances changes according to a function of bone density and according to a function of an interfacing surface shape of the fastener.

MEDICAL PROTECTIVE CLOTHING FABRIC
20220049390 · 2022-02-17 ·

A medical protective clothing fabric includes a Teflon fabric and a petrochemical synthetic filament fabric bonded to the Teflon fabric, where the Teflon fabric and petrochemical synthetic filament fabric are heated and bonded together with high frequency and high pressure, and the fabric hole density of the Teflon fabric is 0.05 μm to 0.1 μm. Whereby, the infectious substances can be prevented from penetrating through the Teflon fabric, and since the Teflon fabric has high temperature resistance, it is not easy to melt, deform or break in a high temperature environment. With the bonding processed with high frequency and high pressure, the processing is simple, the processing cost is significantly reduced, pinholes can further be prevented from being produced, and infectious substance is prevented from penetrating through pinholes. Furthermore, the petrochemical synthetic filament fabric improving wearing comfort allows the medical protective clothing fabric to be waterproof and air permeable.
